Abstract: Novel trophic associations have sometimes resulted in fortuitous and significant biological control. After the invasion of North America by the South American cactus moth, Cactoblastis cactorum (Berg) (Pyralidae: Phycitinae), it is pertinent to characterize the assemblage of local natural enemies that could utilize this moth in new host-parasitoid associations. Herein we report on Apanteles mimoristae Muesebeck (Braconidae: Microgastrinae), a North American gregarious endoparasitoid wasp attacking the caterpillar of the phycitine cactus moth Melitara cf. nephelepasa (Dyar) (Pyralidae: Phycitinae, also known as zebra worm), also native to North America; both collected in Opuntia ficus-indica (L.) Mill. (Cactaceae) cultivated fields at rural areas of Mexico City. We provide an updated morphological account for A. mimoristae visualized with light microscopy and scanning electron microscope (SEM); a fragment of its cytochrome oxidase subunit I (COI) gene sequence data is reported for the first time. Additionally, we analyze its taxonomical position relative to other Apanteles species from the Americas including those attacking cactus-feeding moths. Our analyses place A. mimoristae (from Mexico) in a clade with A. esthercentenoae Fernández-Triana (from Costa Rica), a parasitoid of both Cromarcha stroudagnesia Solis (Pyralidae) and Palpita venatalis (Schaus) (Crambidae) (non cactus-feeding), and in a sister clade to A. opuntiarum Martínez & Berta (from Argentina) and A. alexanderi Brèthes (from Argentina and Uruguay), parasitoids of the cactus-feeding phycitines Cactoblastis and Tucumania respectively. Finally, we provide an updated key for the identification of Apanteles species recorded parasitizing cactus moth caterpillars in the American continent.

A new species of Uscanoidea Girault (Hymenoptera, Trichogrammatidae), an egg parasitoid of Monalonion dissimulatum Distant (Hemiptera, Miridae) https://jhr.pensoft.net/article/111008/ Journal of Hymenoptera Research 97: 191-206

DOI: 10.3897/jhr.97.111008

Authors: Jean Gamboa, Lucía Pérez-Benavides, Esaú Ospina-Peñuela, Francisco Serna, Gennaro Viggiani

Abstract: A new species of Uscanoidea Girault (Hymenoptera: Trichogrammatidae), Uscanoidea ricoi Viggiani, Gamboa & Pérez-Benavides, sp. nov., is described and illustrated. The species is a solitary egg parasitoid of Monalonion dissimulatum Distant (Hemiptera: Miridae), the main insect pest on cocoa crops. An identification key for the described Uscanoidea species of the world is provided. The new species has a high potential for the biological control of the true bug M. dissimulatum in cocoa plantations in the Neotropical region.

Limited phylogeographic structure in a flightless, Appalachian chalcidoid wasp, Dipara trilineata (Yoshimoto) (Hymenoptera, Diparidae), with reassessment of the male of the species https://jhr.pensoft.net/article/115001/ Journal of Hymenoptera Research 96: 1061-1072

DOI: 10.3897/jhr.96.115001

Authors: Michael S. Caterino, Nathan C. Arey

Abstract: Dipara trilineata (Diparidae) is a widespread eastern North American parasitoid with apterous females and winged males. Despite its seemingly limited dispersal capabilities, phylogeographic analysis over southern Appalachia reveals little structure, with only limited population level isolation. DNA barcoding surveys also definitively associate the male of the species, which had previously been misattributed, and a description of the correctly associated male is provided.

The wing interference patterns (WIPs) of Parapanteles (Braconidae, Microgastrinae): demonstrating a powerful and accessible tool for species-level identification of small and clear winged insects https://jhr.pensoft.net/article/111382/ Journal of Hymenoptera Research 96: 967-982

DOI: 10.3897/jhr.96.111382

Authors: Shuyang Jin, Kyle S. Parks, Daniel H. Janzen, Winnie Hallwachs, Lee A. Dyer, James B. Whitfield

Abstract: Wing interference patterns (WIPs) are color patterns of insect wings caused by thin film interference. Thin film interference is the same phenomenon responsible for the refracted spectral colors sometimes visible on soap bubbles. Insect WIPs are static patterns due to the variable thickness of wing membranes and the colors produced depend on the thicknesses of wing membranes. While WIPs have been studied in several taxa of small insects, they have not been broadly adopted by insect taxonomists. We surveyed WIPs in one moderate-sized genus of parasitoid wasps, Parapanteles (Braconidae: Microgastrinae). Using an inexpensive microscope camera set-up and free imaging and analysis software, we detected consistent WIP differences between Parapanteles species. In some cases, WIPs can be used to diagnose sibling species that would otherwise require SEM images to differentiate or DNA barcodes. Wing interference patters are an underemployed character that may be similarly useful in many other taxa of small clear-winged insects.

On the specific epithet “vaccinii” of Ashmead, 1887 and Burks, 1979 (Hymenoptera, Cynipidae) https://jhr.pensoft.net/article/110687/ Journal of Hymenoptera Research 96: 955-965

DOI: 10.3897/jhr.96.110687

Authors: Juli Pujade-Villar, Y. Miles Zhang, Matthew L. Buffington, Denis J. Brothers, Irene Lobato-Vila, Victor Cuesta-Porta

Abstract: Ashmead (1887) provided descriptions of two species of Cynipidae with “vaccinii” as the specific epithet: Solenozopheria vaccinii Ashmead, 1887 and Acraspis vaccinii Ashmead, 1887. There are numerous nomenclatural issues that have arisen from these descriptions. To resolve them, we have examined all relevant primary types and provide images of these specimens, as well as their labels. We recognize as valid the two “vaccinii” species, Loxaulus vaccinii (Ashmead, 1887) and Zopheroteras vaccinii (Ashmead, 1887), and list their synonyms. We also include the following new nomenclatural and taxonomic acts: Acraspis vaccinii Ashmead, 1887: lectotype by present designation; Callirhytis vaccinii Burks, 1979: species incertae sedis; Andricus impositus Beutenmüller, 1918: revalidated status; Andricus verifactor Kinsey, 1922: new status.

First record of the pine sawfly Neodiprion warreni (Hymenoptera, Diprionidae) in the state of Tennessee and on Pinus virginiana https://jhr.pensoft.net/article/112395/ Journal of Hymenoptera Research 96: 937-947

DOI: 10.3897/jhr.96.112395

Authors: Ryan D. Ridenbaugh, Ashleigh N. Glover, Catherine R. Linnen

Abstract: Pine sawflies in the genus Neodiprion Rohwer are widely distributed across the Northern Hemisphere and are pests of commercially important conifer trees. While sampling for Neodiprion species in eastern North America, two colonies of Neodiprion warreni Ross were discovered in Tennessee feeding on Pinus virginiana Mill. These are the first records of N. warreni in Tennessee and on the host P. virginiana. Here, we use a combination of larval and adult female morphology to confirm species identification. We also discuss two potential explanations for these observations: N. warreni was always present in Tennessee and feeding on P. virginiana but, until now, has gone unreported or these new records are attributable to a recent range expansion and host shift. We also discuss potential economic and evolutionary implications of range expansions and host shifts in plant-feeding insect pest species.

An updated molecular phylogeny of the stingless bees of the genus Trigona (Hymenoptera, Meliponini) of the northern Peruvian forests https://jhr.pensoft.net/article/105311/ Journal of Hymenoptera Research 96: 751-760

DOI: 10.3897/jhr.96.105311

Authors: Marilena Marconi, Daniel Ushiñahua Ramírez, Agustín Cerna Mendoza, Carlos Daniel Vecco-Giove, Javier Ormeño Luna, Liliia Baikova, Andrea Di Giulio, Emiliano Mancini

Abstract: Stingless bees (Hymenoptera, Meliponini) are a large and diverse group including 59 extant groups, representing the main pollinators of Amazon forests. Among those, Trigona is one of the largest endemic genera of Neotropical Meliponini. In this work, we updated the molecular phylogeny of Trigona proposed by Rasmussen and Camargo (2008), including data from 59 new specimens collected in 2020 in the forests of northern Peru, through a multigene phylogenetic approach combining sequences from four gene fragments (16S, ArgK, EF-1a, opsin). Our results confirmed the monophyly of Trigona and of all proposed subgenera, except Aphaneura. In addition, most Trigona species-groups resulted monophyletic but the ‘spinipes’ and ‘pallens’ groups appeared paraphyletic and polyphyletic, respectively. Moreover, the cohesion of the “fulviventris” species group was hindered by the inclusion of T. williana (previously included in the “pallens” group) within this clade. Finally, we provided further evidence for a subdivision into two (geographically) distinct clades within T. guianae in northern Peruvian Amazon, which highlighted the importance of Neotropical biogeographical barriers in Meliponini divergence and evolution. Finally, to avoid misidentifications of Trigona specimens, the need for a robust taxonomic revision based on a cladistic approach of the whole genus is discussed.

A new compression fossil, Eotriadomeroides abjunctus Huber, gen. & sp. nov. (Hymenoptera, Mymaridae), in Eocene shale from the Kishenehn Formation, USA https://jhr.pensoft.net/article/107379/ Journal of Hymenoptera Research 96: 657-666

DOI: 10.3897/jhr.96.107379

Authors: John T. Huber, Dale E. Greenwalt

Abstract: A new fossil genus and species of fairyfly, Eotriadomeroides abjunctus Huber & Greenwalt, gen. and sp. nov. (Hymenoptera: Chalcidoidea: Mymaridae), is described and illustrated from a female preserved as a compression fossil in middle Eocene shale from the Kishenehn Formation, Montana, USA. It is compared to extant species of Neotriadomerus Huber, known only from Australia, and Triadomerus Yoshimoto, a Cretaceous amber fossil from Canada. It is suggested that these three genera, classified together in Triadomerini, likely the most ancestral lineage of Mymaridae, are evidence of the Middle or perhaps Late Jurassic origin of the family.

Resident parasitoids associated with Drosophilidae in Michigan tart cherry orchards and woodland edges https://jhr.pensoft.net/article/103160/ Journal of Hymenoptera Research 96: 485-494

DOI: 10.3897/jhr.96.103160

Authors: Juan Huang, Heather Leach, Matthew Buffington, Nikki Rothwell, Julianna K. Wilson

Abstract: Knowledge of the distribution and abundance of resident parasitoid species of Drosophila flies constitutes an important base for developing and implementing a biological control program for Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), an invasive pest that attacks ripening thin-skinned wild and cultivated berries and stone fruits. For this purpose, a field survey was conducted to identify the parasitoid community associated with D. suzukii infested sites in tart cherry orchards and woodlots in west, northwest, and central Michigan. Sentinel traps baited with D. suzukii larvae and pupae in banana slices were deployed in the center of tart cherry orchards, in woodlots adjacent to tart cherry orchards, and in woodlots isolated from any known commercial host of D. suzukii. Traps were placed from the beginning of July to the end of October 2021. Three parasitoid species that are known to use drosophilids as hosts were recovered from these traps. Pachycrepoideus vindemiae (Rondani) (Hymenoptera: Pteromalidae) and Leptopilina boulardi Barbotin, Carton & Keiner-Pillault (Hymenoptera: Figitidae) emerged from the infested bananas. Leptopilina heterotoma (Thomson) was collected as an adult in a sentinel trap. Among these wasps, only P. vindemiae successfully parasitized D. suzukii pupae in the laboratory. This pupal parasitoid was abundant and widely distributed in both cherry orchards and woodlots. The highest number of P. vindemiae was collected from orchards, followed by woodlots adjacent to orchards, with woodlots without nearby cultivated fruit having the lowest detections. These findings suggest that future release of augmentative or classical biological control agents for D. suzukii could be successful in orchards post-harvest to control late-season populations of this pest.

Synopeas maximum Awad & Talamas (Hymenoptera, Platygastridae): a new species of parasitoid associated with soybean gall midge, Resseliella maxima Gagné (Diptera, Cecidomyiidae) https://jhr.pensoft.net/article/102865/ Journal of Hymenoptera Research 96: 181-205

DOI: 10.3897/jhr.96.102865

Authors: Gloria Melotto, Jessica Awad, Elijah J. Talamas, Robert L. Koch, Amelia R. I. Lindsey

Abstract: Synopeas maximum Awad & Talamas, sp. nov., the first reported parasitoid associated with the soybean gall midge, Resseliella maxima Gagné, is described based on morphological and molecular data. Parasitoids were reared from soybean stems infested by R. maxima in Minnesota. A phylogenetic reconstruction of the genus Synopeas Förster was performed with COI sequences (n=2412) available on the Barcode of Life Data System (BOLD). Phylogenetic and barcode gap analyses suggest 279 Synopeas species in this dataset, with S. maximum sequences forming a monophyletic clade that is distinct from relatives. The Synopeas maximum clade was close to specimens from Canada and the United States, suggesting it is native to North America. We present a taxonomic treatment of S. maximum to facilitate its identification, including comparison to morphologically similar species. This project provides baseline data for further ecological study of R. maxima parasitism, and its management in soybean.

Revision of Bethylinae from Dominican amber, with description of a new genus (Hymenoptera, Bethylidae) https://jhr.pensoft.net/article/100862/ Journal of Hymenoptera Research 96: 167-180

DOI: 10.3897/jhr.96.100862

Authors: Diego N. Barbosa, Gabriel A. R. Melo

Abstract: Fossil species of bethyline wasps from Dominican amber are revised. Based on a cladistic analysis of female morphological data we recognize a new genus and species, †Crassibethylus dominicanus gen. et sp. nov., which came out as sister group of the clade Odontepyris + Prosierola. We also transfer to Bethylidae a fossil taxon originally described in Sclerogibbidae, placing †Pterosclerogibba Olmi as a new junior synonym under Goniozus Förster, in the new combination †Goniozus antiquus (Olmi). Additionally, the third species of Bethylinae known from Dominican amber, †Goniozus respectus Sorg, is diagnosed and illustrated with color images of the holotype. An identification key to the species of Bethylinae from Dominican amber is provided.

Melipona beecheii (Hymenoptera, Apidae) foragers deposit a chemical mark on food to attract conspecifics https://jhr.pensoft.net/article/98127/ Journal of Hymenoptera Research 96: 155-166

DOI: 10.3897/jhr.96.98127

Authors: Karen Espadas-Pinacho, Julieta Grajales-Conesa, Julio C. Rojas, Leopoldo Cruz-López

Abstract: Stingless bees have a sophisticated system of chemical communication that helps conspecifics find food sources. In this study, we investigated whether Melipona beecheii foragers deposit a chemical mark on food to recruit conspecifics. Our results showed that foragers preferred to visit the feeders visited previously by conspecifics over clean feeders. We also found that foragers preferred visiting feeders baited with labial gland extracts over those baited with mandibular extracts or hexane. Labial gland extracts elicited higher forager antennal responses compared with those evoked by the mandibular gland extracts or hexane. Labial gland extracts and extracts from feeders visited by foragers contain a mixture of unsaturated hydrocarbons, followed by straight chain hydrocarbons and small quantities of esters. The main component is a mixture of alkene isomers C27:1.

Sexual dimorphism in excess power index of four North American native bees (Hymenoptera, Andrenidae, Apidae, and Halictidae) https://jhr.pensoft.net/article/98652/ Journal of Hymenoptera Research 96: 121-128

DOI: 10.3897/jhr.96.98652

Authors: Patrick A. Vigueira, Cynthia C. Vigueira, Joshua W. Campbell, Samia Ladner, Gabrielle Hayes, Elizabeth Riser

Abstract: A multitude of hymenopteran species exhibit sexual dimorphism for simple traits, such as color, size, or antennal segment number. These differences can reflect selection for specialized biological roles, many of which have not been documented for the majority of bee and wasp species. The excess power index (EPI) is an estimate of insect flight performance that is inferred by the combination of several morphological characteristics. We compared the female and male EPIs in four species of native bees: Agapostemon virescens Fabricius, Andrena carlini Cockerell, Melissodes bimaculata Lepeletier and Xylocopa virginica L.. While females of each species had a significantly larger whole body mass, males had a significantly larger EPI. A larger body mass for females is associated with egg laying abilities and foraging behavior. Male fitness may be dependent on EPI; males that have greater flight capacity can travel further or remain in flight for longer time periods in search of mates.

Detection and description of four Vespa mandarinia (Hymenoptera, Vespidae) nests in western North America https://jhr.pensoft.net/article/99307/ Journal of Hymenoptera Research 96: 1-20

DOI: 10.3897/jhr.96.99307

Authors: Chris Looney, Brant Carman, Jenni Cena, Cassie Cichorz, Vikram Iyer, Jessica Orr, Nathan Roueché, Karla Salp, Jacqueline M. Serrano, Landon Udo, Paul van Westendorp, Telissa M. Wilson, Rian Wojahn, Sven-Erik Spichiger

Abstract: Vespa mandarinia Smith 1852 is a semi-specialized predator of other social Hymenoptera and one of the two largest species of Vespa. Several individuals of this predatory wasp were detected in Canada and the United States in 2019, including an entire nest that was located and destroyed on Vancouver Island, British Columbia. The Washington State Department of Agriculture and the United States Department of Agriculture’s Animal and Plant Health Inspection Service have collaborated to survey Washington State for V. mandarinia since 2020, using traps staffed by agency personnel, collaborators from local governments and nongovernmental organizations, and the general public. Trap data and public reports were used to select sites for live-trapping or net surveys, and live hornets captured in these efforts were subsequently collected and fitted with radio tags to locate nests. The survey ultimately led to the discovery of a V. mandarinia nest in October 2020, and three nests in August and September 2021. All of the nests were located within in red alder trees (Alnus rubra), with one just above the ground in a standing dead tree, and the other three in cavities ~2 to 5 meters above the ground in living trees. The number of combs in each nest varied between four and ten, cells between 418 and 1,329, and total hornets per nest between 449 and 1,474 (including immature and mature stages). Together, the four nests indicate an incipient population of V. mandarinia in the Cascadia region, and ongoing action by local, state, provincial, and federal governments, and residents of both countries is required to avoid the establishment of this exotic species in the region.

The North American bees of the genus Ptilothrix Cresson, 1878 (Hymenoptera, Apidae, Emphorini), with the description of two new species https://jhr.pensoft.net/article/96025/ Journal of Hymenoptera Research 95: 275-293

DOI: 10.3897/jhr.95.96025

Authors: Nathalia Flórez-Gómez, Bryan Danforth

Abstract: Ptilothrix Cresson is a genus of New World bees with an amphitropical distribution. Like other genera in the tribe Emphorini, Ptilothrix have narrow pollen preferences. These solitary ground-nesting bees exhibit a remarkable nesting behavior in which females carry water from ponds to facilitate the excavation of the hard soil where they nest. With 16 described species, there are few taxonomic studies and, before this work, a lack of taxonomic treatments for the species in North America. Thus, in this study we revised and recognized four species for the region: Ptilothrix bombiformis Cresson, Ptilothrix sumichrasti Cresson, Ptilothrix chiricahua Florez-Gomez & Danforth, sp. nov. and Ptilothrix zacateca Florez-Gomez & Danforth, sp. nov. We describe and illustrate males and females of the two new species. We also present diagnoses for the four species, a key to identify them, and a map of their geographic distributions.

Taxonomy of the genus Peucobius Townes (Hymenoptera, Ichneumonidae, Sisyrostolinae) https://jhr.pensoft.net/article/98222/ Journal of Hymenoptera Research 95: 245-260

DOI: 10.3897/jhr.95.98222

Authors: Andrey I. Khalaim, Enrique Ruíz-Cancino, Juana Maria Coronado-Blanco

Abstract: The genus Peucobius Townes previously comprised two species occurring in the Nearctic region: P. fulvus Townes and P. piceus Townes. In the current study we revise this genus, transfer it to the subfamily Sisyrostolinae (comb. nov.), and describe two new species – P. bennetti Khalaim & Ruíz-Cancino, sp. nov. from Central Mexico and P. shimizui Khalaim, sp. nov. from Japan. The genus Lygurus Kasparyan occurring in Russian Far East and Taiwan is morphologically similar to Peucobius; characters for distinguishing these two genera are provided for the first time with the use of colour photographs. Identification keys to four world species of Peucobius, and to species of Lygurus and Peucobius occurring in the East Palaearctic region, are provided. We suggest that species of Peucobius are associated with xyelid sawflies (Xyelidae) whose larvae feed in staminate pine cones.

Niche modeling of bumble bee species (Hymenoptera, Apidae, Bombus) in Colombia reveals highly fragmented potential distribution for some species https://jhr.pensoft.net/article/87752/ Journal of Hymenoptera Research 95: 231-244

DOI: 10.3897/jhr.95.87752

Authors: Laura Rojas-Arias, Daniel Gómez-Morales, Stephanie Stiegel, Rodulfo Ospina-Torres

Abstract: Insect population decline has been reported worldwide, including those of pollinators important for ecosystem services. Therefore, conservation actions which rely on available rigorous species distribution data are necessary to protect biodiversity. Niche modeling is an appropriate approach to distribution maps, but when it comes to bumble bees, few studies have been performed in South America. We modeled ecological niches of nine Colombian Bombus species with MAXENT 3.4 software using bioclimatic variables available from WorldClim. This resulted in maps for each species that show the potential distribution area at the present time. Modeled species maps accurately represent potential niches according to the description of bioclimatic conditions in the species’ habitat. We grouped the species into three clusters based on our results, as well as on distributional information from literature on the topic: High Mountain, Mid- Mountain and inter-Andean, and the Amazon and Eastern Plains Basin. Niche modeling depicted bumble bee species’ distribution in Colombia, the results of which can serve as a useful tool for conservation policies in the country.

Taking care of the enemy: egg predation by the Darwin wasp Tromatobia sp. (Ichneumonidae) on the cobweb spider Chrysso compressa (Araneae, Theridiidae) https://jhr.pensoft.net/article/97029/ Journal of Hymenoptera Research 95: 103-112

DOI: 10.3897/jhr.95.97029

Authors: Brenda Kelly Souza-Santiago, Yuri Fanchini Messas, Diego Galvão de Pádua, Adalberto J. Santos, João Vasconcellos-Neto

Abstract: Some wasp species use spiders as food resources, overcoming several anti-predator barriers that are exerted by spiders. Tromatobia ichneumonid wasps are spider egg predators that usually attack Araneidae species, although there are few records of predation on Clubionidae, Philodromidae, Linyphiidae, Tetragnathidae, and Theridiidae spiders. Here, we describe the interaction between Tromatobia sp. and Chrysso compressa, a subsocial theridiid spider that exhibits extended maternal care, in the Atlantic Forest of southeastern Brazil. We observed that the larva of Tromatobia sp. develop inside the egg sacs of C. compressa, preying on the entire egg mass and building cocoons that change the color and morphology of the egg sacs. Despite these structural modifications, we registered an adult female of C. compressa guarding and caring for the cocoons (attacked egg sac) of the predators as if they were offspring (non-attacked egg sac). To the best of our knowledge, this study represents the first record of Tromatobia preying on Chrysso eggs.

Ovipositor characteristics differ between two parasitoids (Hymenoptera, Figitidae) of Drosophila suzukii (Diptera, Drosophilidae) in an adventive landscape https://jhr.pensoft.net/article/89678/ Journal of Hymenoptera Research 95: 13-30

DOI: 10.3897/jhr.95.89678

Authors: Nathan G. Earley, Paul K. Abram, Robert G. Lalonde, Chandra E. Moffat

Abstract: Different ovipositor characteristics among parasitoid species that share similar niches are associated with different wasp life histories and selective pressures. The length of wasp ovipositors, for example, can determine the accessibility of hosts that feed at different depths within food substrates. Two parasitoids, Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera, Figitidae), which attack Drosophila suzukii (Diptera, Drosophilidae) in their native range, have been investigated for their suitability for the global biological control of the small fruit pest. Despite their sympatry in microhabitat, the parasitoids have differing host ranges, and D. suzukii parasitism rates by each parasitoid species appear to depend on the fruit species occupied by the host species. Adventive populations of both parasitoids have been detected in the Pacific Northwest of Canada and the United States where they can be found parasitizing D. suzukii larvae in crop and non-crop fruits. We dissected and measured the ovipositors of parasitoids reared from three species of fresh fruits at three sites in southwestern British Columbia, Canada, and investigated the influence of parasitoid species, fruit type, and collection site on ovipositor characteristics. We found that ovipositor length differed markedly between the two parasitoid species and between sites while ovipositor width, and stoutness, differed only between the two parasitoid species, but did not vary among sites or fruit hosts. We discuss how ovipositor morphology traits could be associated with differences in life history and host ranges in the two parasitoid species.

Abstract: Several bumble bee species (Bombus Latreille) are declining and efforts to conserve populations will be strengthened by an improved knowledge of their geographic distribution. Knowledge gaps exist, however, especially in central portions of North America. Here we report 29 species of bumble bees from South Dakota in the north-central USA, based on 130 years of records from 1891 to 2021. Specimens or observations were available for >90% of the 66 counties, though they were not distributed evenly as most records came from Pennington, Lawrence, Custer, Brookings, and Day Counties. The five most commonly collected or reported bumble bee species were B. griseocollis (54 counties), B. pensylvanicus (41 counties), B. fervidus (39 counties), B. huntii (27 counties), and B. bimaculatus (25 counties). Twenty species were recorded from 10 or fewer counties. Despite differences in occurrence, 66% of the Bombus species in South Dakota were collected or observed since 2020, including six of the nine species of conservation concern (B. fraternus, B. pensylvanicus, B. fervidus, B. occidentalis, B. terricola, and B. morrisoni). However, the critically endangered B. affinis, B. variabilis, and B. suckleyi have not been collected or observed for over 50 years. While this checklist is the first for South Dakota bumble bees in nearly 100 years, data are still lacking as ~55% of counties had fewer than five species reported. We suggest future efforts should focus on these under-sampled areas to fill in baseline knowledge of the wild bee fauna towards completing a more holistic view of bumble bee distributions across the Great Plains.

Integrative approach resolves the taxonomy of Eulaema cingulata (Hymenoptera, Apidae), an important pollinator in the Neotropics https://jhr.pensoft.net/article/91001/ Journal of Hymenoptera Research 94: 247-269

DOI: 10.3897/jhr.94.91001

Authors: Tamires de Oliveira Andrade, Kelli dos Santos Ramos, Margarita M. López-Uribe, Michael G. Branstetter, Carlos Roberto F. Brandão

Abstract: Species delimitation is a rich scientific field that often uses different sources of data to identify independently evolving lineages that might be recognized as species. Here, we use an integrative approach based on morphometrics, COI-barcoding, and phylogenomics using ultraconserved elements (UCEs) to investigate whether the orchid bee species Eulaema cingulata (Fabricius, 1804) and E. pseudocingulata Oliveira, 2006 represent a single variable taxon or two different species. We analyzed 126 specimens across the geographical range of these nominal species to test species hypotheses using the general lineage concept. We found substantial overlap in wing and head morphometrics, and both taxa form one phylogenetic lineage based on COI mitochondrial and UCE data. Our results support the recognition of both forms as members of the same evolutionary unit and E. pseudocingulata is herein recognized as a junior synonym of E. cingulata.

Encarsia hera Lahey & Andreason (Hymenoptera, Aphelinidae): a charismatic new parasitoid of Aleurocybotus Quaintance & Baker (Hemiptera, Aleyrodidae) from Florida https://jhr.pensoft.net/article/94677/ Journal of Hymenoptera Research 94: 89-104

DOI: 10.3897/jhr.94.94677

Authors: Zachary Lahey, Alvin M. Simmons, Sharon A. Andreason

Abstract: A new, biparental species of the genus Encarsia Förster (Hymenoptera: Aphelinidae), E. hera Lahey & Andreason, sp. nov., is characterized based on morphological and molecular data. The parasitoid was reared from the puparia of its host, an undescribed species of the grass-feeding aleyrodine genus Aleurocybotus Quaintance & Baker (Hemiptera: Aleyrodidae) collected in Gainesville, Florida. The same whitefly is newly recorded from Charleston, South Carolina, where it is a pest of ornamental Muhly grass [Muhlenbergia capillaris (Lam.) Trin. (Poaceae)]. A phylogenetic analysis based on a fragment of 28S ribosomal DNA in 34 Encarsia species placed E. hera, sp. nov., within the E. luteola-group, a result concordant with its morphology. A key to the Encarsia species reared from Aleurocybotus is provided.

Host plant and immature stages of Setabara histrionica (MacGillivray) (Hymenoptera, Tenthredinidae) https://jhr.pensoft.net/article/93555/ Journal of Hymenoptera Research 94: 1-11

DOI: 10.3897/jhr.94.93555

Authors: Quinlyn Baine, David R. Smith, Bill Zakopyko, Sapphitah Dickerson, Chris Looney

Abstract: The North American sawfly Setabara histrionica (Tenthredinidae: Heterarthrinae) is previously known only from adult collections but has been hypothesized to feed upon trees in the genus Prunus. We discovered a population of leaf-mining sawflies in Washington on Prunus emarginata and identified it as S. histrionica using combined morphological and molecular analysis. We observed preference in oviposition site selection on the host plant, with most eggs deposited on the margin of the basal third of the leaf, and on leaves growing within 1 meter of the ground. We include a description of the egg, larval stages, mine and phenology of S. histrionica, and an update to Smith’s (1971) key to Heterarthrinae larvae.

Nesting of the keyhole wasp Pachodynerus nasidens (Latreille, 1812) (Vespidae, Eumeninae) in a nest of a paper wasp (Vespidae, Polistinae) https://jhr.pensoft.net/article/91298/ Journal of Hymenoptera Research 93: 125-130

DOI: 10.3897/jhr.93.91298

Authors: Gabriel de Castro Jacques, Wellington Donizet Ferreira, Paola Aparecida Moura, Gabriel Teofilo-Guedes, Marcos Magalhães de Souza

Abstract: Potter wasps (Hymenoptera, Vespidae, Eumeninae) adopt different substrates for nesting, including other wasp nests. Nevertheless, such behavior rarely occurs with abandoned nests of the paper wasps (Hymenoptera, Vespidae, Polistinae). In this study, we report the occurrence involving the nesting of a potter wasp on a paper wasp’s nest. Such a record occurred in November 2021 in a segment of a deciduous forest, at Mata Seca State Park, Southeast Brazil. An abandoned Polistinae nest was found, with 14 cells sealed with mud, from which four male Pachodynerus nasidens individuals emerged. This record of P. nasidens reusing a Polistinae’s nest increases our knowledge of Eumeninae nesting strategies and on possible associations between different groups of vespid wasps.

Cecinothofagus Nieves-Aldrey & Liljeblad (Hymenoptera, Cynipidae) is likely an endoparasitoid of the gall-maker genus Aditrochus Rübsaamen (Hymenoptera, Pteromalidae) https://jhr.pensoft.net/article/89507/ Journal of Hymenoptera Research 93: 33-42

DOI: 10.3897/jhr.93.89507

Authors: Jean-Yves Rasplus, José-Luis Nieves-Aldrey, Astrid Cruaud

Abstract: Paraulax Kieffer and Cecinothofagus Nieves-Aldrey & Liljeblad (Cynipidae: Paraulacini) were long supposed to be gall-makers on southern beeches (Nothofagus, Nothofagaceae). Dissections of galls on Nothofagus Blume, suggested that Cecinothofagus could be instead either endoparasitoid or inquiline of Aditrochus larva (Chalcidoidea). We sequenced the universal COI barcode and Ultra-Conserved Elements (UCEs) from young larvae of Aditrochus collected from galls on Nothofagus and highlighted that one of them also contained DNA from Cecinothofagus ibarrai Nieves-Aldrey & Liljeblad. So far, when galls attributed to Aditrochus were dissected in early development stages they all contained only a single larva and no remains of other larvae. Conversely, when Cecinothofagus ibarrai was reared from galls on Nothofagus, remains of the host larva were observed inside the larval chamber. Altogether, biological observations and molecular results suggest that Cecinothofagus ibarrai is likely an endoparasitoid of Adritrochus. This result confirms the tribe Paraulacini as being entomophagous and supports the hypothesis of an ancestral parasitoid lifestyle for Cynipoidea.

Host-specific demography of Utetes anastrephae (Hymenoptera, Braconidae), a native parasitoid of Anastrepha spp. fruit flies (Diptera, Tephritidae) https://jhr.pensoft.net/article/86860/ Journal of Hymenoptera Research 93: 53-69

DOI: 10.3897/jhr.93.86860

Authors: María Dina Estrada-Marroquín, Jorge Cancino, Daniel Sánchez, Pablo Montoya, Pablo Liedo

Abstract: The braconid Utetes anastrephae (Viereck, 1913) (Hymenoptera: Braconidae) is a larva-pupal parasitoid of fruit flies of the genus Anastrepha Schiner, commonly associated with Anastrepha obliqua (Macquart, 1835) (Diptera: Tephritidae), the most important pest of mango (Mangifera indica L., 1753) in Mexico. This parasitoid was established in a laboratory colony using larvae of Anastrepha ludens (Loew, 1873) as host. Here we describe a demographic study to compare the reproductive and population parameters of this parasitoid reared on A. obliqua and A. ludens under laboratory conditions. Two U. anastrephae cohorts of 30 individual pairs each were set up, one was reared on A. obliqua larvae and the other one on A. ludens. Every day, 30 third instar larvae of each host species were exposed to an adult pair through the lifespan of the female. Daily mortality and fecundity were recorded. Life tables were constructed and sex ratios, parasitism rates, survival, reproductive and population parameters were estimated. Higher survival of U. anastrephae females was observed in females from A. obliqua (mean live expectancy of 22.4 days), but higher fecundity and parasitism occurred in females from A. ludens (net fecundity of 62.61 daughters/ female and 16.72% parasitism rate). The intrinsic rate of increase (r = 0.128 and r = 0.134 for A. obliqua and A. ludens respectively), mean generation time (27.88 and 28.30 days) and population doubling time (5.42 and 5.16 days) were similar in both cohorts, as well as the sex ratio (73 and 69% of females). These results suggest that A. ludens as host increase the production rates; however, any one of these two species could be used as host for mass rearing purposes.

Hygienic behavior and antimicrobial peptide expression of the leaf-cutting ant Atta cephalotes (Hymenoptera, Formicidae) to Metharhizium anisopliae https://jhr.pensoft.net/article/82381/ Journal of Hymenoptera Research 91: 335-356

DOI: 10.3897/jhr.91.82381

Authors: Juan Sebastián Gómez-Díaz, Andrea Niño-Castro, Sandra Milena Valencia-Giraldo, Karent Mariana Cotazo-Calambas

Abstract: Leaf-cutting ants depend on mutualisticfungi to survive. An infection that massively affects the workers compromising the proper maintenance of the fungus, or that can attack the fungus garden, can be fatal to the colony. Thus, leaf-cutting ants have evolved a complex defense system composed of both innate individual immunity and collective immunity to protect the colony against potential threats. To characterize the collective and individual immunity of Atta cephalotes workers to Metarizhium anisopliae we assessed the hygienic behavior and the expression of antimicrobial peptides of A. cephalotes workers triggered by Metarizhium anisopliae spores. As a control challenge, workers were treated with water. Regardless of whether the challenge was with water or spore suspension, A. cephalotes workers displayed an immediate response characterized by an increase in time spent both self-grooming and collective grooming along with a reduction in time spent fungus-grooming. The individual immunity triggered the expression of abaecin as early as 24 hours post-infection, exclusively in workers challenged with M. anisopliae. In contrast, the level of expression of defensin remained constant. These results suggest that upon being challenged with a suspension of M. anisopliae spores, A. cephalotes workers deploy both collective and individual immunity to produce a response against the invader. However, when the spores of M. anisopliae are applied as liquid suspension collective immunity deploys a generic strategy, while individual immunity shows a specific response against this entomopathogen.

Review of adult diapause in ichneumonid wasps (Hymenoptera, Ichneumonidae) https://jhr.pensoft.net/article/83618/ Journal of Hymenoptera Research 91: 185-208

DOI: 10.3897/jhr.91.83618

Authors: Fons Verheyde, Donald L. J. Quicke

Abstract: The mechanisms and ecological circumstances of adult diapause in Ichneumonidae are poorly studied. An overview is presented of what observations and research have been carried out on ichneumonid diapause to date, and new ecological and distributional data are presented. The new data primarily concerns species that hibernate in association with trees, based on observations made in Belgium and the Netherlands. A preliminary checklist of the 50 species that are now known to hibernate is provided for both these countries. Auberteterus alternecoloratus (Cushman, 1929), Dicaelotus montanus (de Stefani, 1885), Dicaelotus pictus (Schmiedeknecht, 1903) and Orthocentrus sannio Holmgren, 1858 are reported as adult hibernators for the first time. Four species are newly recorded for the Belgian or Dutch faunas.

Detection of Centistes sp. (Hymenoptera, Braconidae) from intercepted Diabrotica undecimpunctata (Coleoptera, Chrysomelidae) using CO1 DNA barcodes and larval morphology https://jhr.pensoft.net/article/84139/ Journal of Hymenoptera Research 91: 69-81

DOI: 10.3897/jhr.91.84139

Authors: Christina R. Wilson, Crystal Cooke-McEwen, Todd M. Gilligan, Luke R. Tembrock

Abstract: Globalized trade has resulted in the incidental translocation of numerous insect species, some of which have become invasive in their expanded ranges. While rigorous inspection programs are a regular part of commodity importation, rarely if ever are the internal contents of intercepted insects examined. As part of a genetic diversity project on intercepted Diabrotica undecimpunctata beetles, we detected CO1 DNA that closely matched sequences from Centistes parasitoid wasps in 9% of our samples. The presence of internal parasitoids was confirmed through dissections and imaging, wherein the samples were morphologically consistent with Centistes larvae. Such a discovery suggests that insect translocation as part of trade can be more diverse than initially thought. The case of Centistes in imported Diabrotica may present a positive benefit specifically to agroecosystems through the biological control of pest beetles like Diabrotica. However, drawbacks from such introductions include off-target parasitism of non-pest beetles and resultant impacts to insect populations in undisturbed ecosystems. Thus, examination of intercepted insects beyond the initial species identification is warranted to better understand the potential impacts of human mediated insect translocations. Methods employing high-throughput sequencing and metabarcoding are well suited for such broad-scale identification projects where Diabrotica would be an excellent candidate for this work.

Resurrection of Neocardiochiles Szépligeti, 1908 (Hymenoptera, Braconidae, Cardiochilinae) with descriptions of five new species from the Neotropical region https://jhr.pensoft.net/article/84937/ Journal of Hymenoptera Research 91: 41-68

DOI: 10.3897/jhr.91.84937

Authors: Ilgoo Kang, James B. Whitfield, Brittany E. Owens, Junyan Chen

Abstract: Neocardiochiles Szépligeti, 1908, is a rare Neotropical genus of the subfamily Cardiochilinae Ashmead, 1900. The genus was previously synonymized with Heteropteron Brullé, 1846 by Dangerfield et al. (1999). In this study, we examined multiple specimens of Heteropteron-related genera: Heteropteron, Neocardiochiles, and Wesmaelella Spinola, 1851, and resurrect Neocardiochiles as a valid genus based on morphological data. As a result, five new species, N. alexeyi Kang, sp. nov. from Ecuador, N. franki Kang, sp. nov. from Costa Rica, N. braeti Kang, sp. nov., N. chriscarltoni Kang, sp. nov., and N. victoriae Kang, sp. nov., from French Guiana are included as members of Neocardiochiles and described based on morphological and molecular data. Additionally, four species previously included in Heteropteron are transferred to Neocardiochiles: Neocardiochiles fasciipennis Szépligeti, 1908, comb. nov., Neocardiochiles hasegawai (Dabek & Whitfield, 2020) comb. nov., Neocardiochiles kidonoi (Dabek & Whitfield, 2020), comb. nov., and Neocardiochiles whitfieldi (Mercado, 2003), comb. nov.. Diagnosis of each taxon and both traditional and interactive identification keys to Neocardiochiles species are included. Molecular data of N. alexeyi sp. nov., N. chriscarltoni sp. nov., N. victoriae sp. nov., and N. hasegawaii (Dabek & Whitfield, 2020), are also provided.

First records of adventive populations of the parasitoids Ganaspis brasiliensis and Leptopilina japonica in the United States https://jhr.pensoft.net/article/82812/ Journal of Hymenoptera Research 91: 11-25

DOI: 10.3897/jhr.91.82812

Authors: Elizabeth H. Beers, Dylan Beal, Peter Smytheman, Paul K. Abram, Rebecca Schmidt-Jeffris, Erica Moretti, Kent M. Daane, Chris Looney, Chia-Hua Lue, Matthew Buffington

Abstract: We report the first known incidence of two parasitoid species of the invasive pest, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), in the United States (US). The discovery of Ganaspis brasiliensis (Ihering) (Hymenoptera: Figitidae) and Leptopilina japonica (Novković & Kimura) (Hymenoptera: Figitidae) in northwestern Washington State (US) was made shortly after their discovery in nearby southwestern British Columbia (Canada), indicating that contiguous populations of these species are established in both countries. The first specimen of L. japonica from Washington was collected in the fall of 2020, when it was found in a rice wine/orange juice trap deployed to survey for Vespa mandarinia Smith (Hymenoptera: Vespidae). Subsequent examination of trap contents from the 2020–2021 seasons indicated the presence of both L. japonica and G. brasiliensis. In September of 2021, live collections of both G. brasiliensis and L. japonica were made, reared from D. suzukii-infested Himalayan blackberry in Whatcom County, WA. Adult parasitoid identifications were based on morphology and COI DNA barcodes. All sequenced specimens to date from Washington and British Columbia belong to the G1 group of G. brasiliensis, the only group approved for release as a classical biological control agent in the US. This study provides an example of how even small changes in the geographic range of a natural enemy, now extending across an international border, may have significant consequences for the future of a biological control program.

Clarification of the status of Paraferreola Šustera, 1912 as an available genus name in Pompilidae, and the identity of Sphex ursus Fabricius, 1793 in Mutillidae (Hymenoptera) https://jhr.pensoft.net/article/84964/ Journal of Hymenoptera Research 91: 429-444

DOI: 10.3897/jhr.91.84964

Authors: Denis J. Brothers, Arkady S. Lelej, Kevin A. Williams

Abstract: The usage of Paraferreola Šustera, 1912 since its proposal as a genus of spider wasps, but based on a misidentified type species (Sphex ursus Fabricius, 1793, actually a species of Mutillidae), shows that it continues to be applied (although infrequently) in Pompilidae, despite the proposal of new names (Eoferreola Arnold, 1935 and Tea Pate, 1946) for the equivalent generic concept. Application of Article 70.3.2 of the fourth edition of the International Code of Zoological Nomenclature permits correction of the erroneous type species designation to that originally intended (Sphex rhombica Christ, 1791), and thus the maintenance of Paraferreola as a valid genus in Pompilidae. Examination of the holotype specimen of Sphex ursus has shown it to be a senior synonym of Mutilla vesta Cresson, 1865 and its junior synonyms, for which the valid name must thus be Dasymutilla ursus (Fabricius, 1793), comb. nov.

Discovery of Mourecotelles (Hymenoptera, Apidae, Colletinae) in Brazil: nesting biology and pollen preferences of a remarkable new species of the genus https://jhr.pensoft.net/article/77485/ Journal of Hymenoptera Research 89: 211-231

DOI: 10.3897/jhr.89.77485

Authors: Rafael R. Ferrari, Maria L. T. Buschini, Mary E. R. Diniz, Chao-Dong Zhu, Gabriel A. R. Melo

Abstract: Mourecotelles Toro & Cabezas (Hymenoptera, Apidae, Colletinae) currently includes only nine valid species of cellophane bees found mostly in relatively-dry regions of western South America (Chile, Argentina, Bolivia, and Ecuador). In this paper, we describe and illustrate a new species of the genus – M. braziliensis Ferrari & Melo, sp. nov. – based on individuals of both sexes captured through trap-nesting in an environmental protection area (Araucárias Municipal Natural Park) and in flowers in different localities in southern Brazil. In total, we obtained 16 nests of M. braziliensis, each consisting of two to eleven brood cells arranged horizontally and lined with a cellophane-like substance. Of the 57 adult bees that emerged, 41 were male (mean weight 46.5 mg) and 16 were female (mean weight 58.9 mg), resulting in biased sex and investment ratios of 2.56:1 and 2.02:1, respectively. Both the numbers of provisioned cells and mortality rate were higher for trap nests with the narrowest bore diameter, although the differences in relation to other trap nests were not statistically significant. Pollen of nine different plant families were found in brood cells of M. braziliensis, but the species showed a clear preference for Fabaceae and Polygalaceae. Indeed, some of the specimens were collected while foraging in flowers of an unidentified species of Monnina Ruiz & Pav. (Polygalaceae) growing in swampy areas. The evolutionary and biogeographical implications of our discovery are briefly discussed.

Assessment of an inexpensive trap design and survey method for vespine wasps (Hymenoptera, Vespidae, Vespinae) https://jhr.pensoft.net/article/80284/ Journal of Hymenoptera Research 89: 171-182

DOI: 10.3897/jhr.89.80284

Authors: Grady O. Jakobsberg, Walter D. Mooney, Jacqueline Rangel-Sanchez

Abstract: The introduction of the predatory Giant Asian Hornet, Vespa mandarinia Smith, to North America in 2019 has motivated efforts to create early detection systems for this and other non-native social wasp species (Hymenoptera, Vespidae). Various trap and bait combinations have been used for this purpose, most of which require assembly and materials that are costly, reducing their usefulness in large-scale survey systems. This study tests an inexpensive and efficient trapping technique for detecting or surveying vespine wasps. Traps were made from reused plastic bottles containing a brown sugar and water bait. They were deployed at heights ranging from 0–6 m above ground in several configurations. Captures for traps suspended 1 m or greater above ground were, on average, nine times higher than the catch of ground-level traps. A rapid trap deployment method for large geographic areas was created, which captured seven different vespine wasp species along a 395 km east-west road transect from mountains to coastal plain in the Mid-Atlantic region of the United States. The trapping design and survey methodology described below is inexpensive and fast and could be used by land managers or citizen scientists to detect V. mandarinia, other exotic vespine, or conducted on a large-scale vespine diversity survey.

Inclusion of an alien species in the host range of the Neotropical parasitoid Hymenoepimecis bicolor (Brullé, 1846) (Hymenoptera, Ichneumonidae) https://jhr.pensoft.net/article/76620/ Journal of Hymenoptera Research 89: 9-18

DOI: 10.3897/jhr.89.76620

Authors: Marcelo O. Gonzaga, Diego G. Pádua, Adilson Quero

Abstract: In this study we report the first case of an introduced alien host spider species being parasitized and manipulated by an ichneumonid wasp. Hymenoepimecis bicolor, previously described parasitizing exclusively Trichonephila clavipes (Araneidae), was observed parasitizing the European species Cyrtophora citricola (Araneidae) in southeastern Brazil. The cocoon web built by the parasitized spider is composed of a reduced horizontal sheet, which maintains the radial structure. The reduced number of radii and spirals probably reduce the chances of insect interception by these modified structures. In addition, the density of supporting threads is apparently very different between normal and modified webs. The cocoon web spun by C. citricola lacks the protective barrier structure usually observed in cocoon webs spun by parasitized females of T. clavipes. Our observations are in agreement with several predictions of the ecdysteroid hypothesis and represent an interesting opportunity for further investigation of interactions between these parasitoids and their spider hosts.

Azteca ants repair damage to their Cecropia host plants https://jhr.pensoft.net/article/75855/ Journal of Hymenoptera Research 88: 61-70

DOI: 10.3897/jhr.88.75855

Authors: Alex Wcislo, Xavier Graham, Stan Stevens, Johannes Ehoulé Toppe, Lucas Wcislo, William T. Wcislo

Abstract: Some Azteca ants are well-known symbionts that defend their Cecropia host plants against herbivory, although there is considerable variability in behavior among colonies, conditions, and species. In exchange, ants receive food, and also shelter within the plants’ internodes. Here we demonstrate that ants repair damage to the host plant when their brood is directly threatened. Using comminuted plant fibers and an unidentified binding liquid (probably plant sap) ants generally began patching holes in the tree trunk immediately, and significantly reduced the size of the hole 2.5 hours after it was created, and they generally completed the repairs within 24 hours.

Phenological and social characterization of three Lasioglossum (Dialictus) species inferred from long-term trapping collections https://jhr.pensoft.net/article/73220/ Journal of Hymenoptera Research 88: 17-38

DOI: 10.3897/jhr.88.73220

Authors: Lyllian A.-J. Corbin, David N. Awde, Miriam H. Richards

Abstract: Detailed social and phenological data collected from nesting aggregations exist for relatively few sweat bee species because nesting aggregations are rarely found in large numbers, even when local populations are highly abundant. This limits researchers’ abilities to assess the social status of many species, which in turn, limits our ability to trace the sequence of evolutionary steps between alternative social states. To address this problem, we demonstrate the utility of rehydrated, pinned specimens from pan trap and netting collections for generating inferences about the phenology and social status of a well-studied sweat bee species, Lasioglossum (Dialictus) laevissimum. A detailed comparison of phenology and reproductive traits, between pinned specimens and those in a previous nesting study, produced similar results for bivoltine foraging activity and eusocial colony organization typical in this species. We then used pinned specimens from monitoring studies to describe, for the first time, the foraging phenology and social behaviour of two additional Dialictus species, L. hitchensi and L. ellisiae. Both L. hitchensi and L. ellisiae each exhibited two peaks in abundance during their breeding seasons, indicating two periods of foraging activity, which correspond to provisioning of spring and summer broods. Differences in body size, wear, and ovarian development of spring and summer females indicated that L. hitchensi is most likely eusocial, while L. ellisiae is either solitary or communal. This study demonstrates that analyses of specimens obtained from flower and pan trap collections can be used for assessing the phenology and social organization of temperate sweat bees in the absence of nesting data. The phenological and social lability of many sweat bee species make them ideal for studying geographic and temporal variability in sociality, and analyses of pan trap collections can make these studies possible when direct observations are impossible.

Authors: István Mikó, Lubomir Masner, Jonah M. Ulmer, Monique Raymond, Julia Hobbie, Sergei Tarasov, Cecilia Beatriz Margaría, Katja C. Seltmann, Elijah J. Talamas

Abstract: Teleasinae are commonly collected scelionids that are the only known egg parasitoids of carabid beetles and therefore play a crucial role in shaping carabid populations in natural and agricultural ecosystems. We review the available host information of Teleasinae, report a new host record, and revise Gryonoides Dodd, 1920, a morphologically distinct teleasine genus. We review the generic concept of Gryonoides and provide diagnoses and descriptions of thirteen Gryonoides species and two varieties: G. glabriceps Dodd, 1920, G. pulchellus Dodd, 1920 (= G. doddi Ogloblin, 1967, syn. nov. and G. pulchricornis Ogloblin, 1967, syn. nov.), G. brasiliensis Masner & Mikó, sp. nov., G. flaviclavus Masner & Mikó, sp. nov., G. fuscoclavatus Masner & Mikó, sp. nov., G. garciai Masner & Mikó, sp. nov., G. mexicali Masner & Mikó, sp. nov., G. mirabilicornis Masner & Mikó, sp. nov., G. obtusus Masner & Mikó, sp. nov., G. paraguayensis Masner & Mikó, sp. nov., G. rugosus Masner & Mikó, sp. nov., G. uruguayensis Masner & Mikó, sp. nov. We treat Gryonoides scutellaris Dodd, 1920, as status uncertain. Gryonoides mirabilicornis Masner & Mikó, sp. nov. is the only known teleasine with tyloids on two consecutive flagellomeres, a well-known trait of Sparasionidae. An illustrated identification key to species of Gryonoides, a queryable semantic representation of species descriptions using PhenoScript, and a simple approach for making Darwin Core Archive files in taxonomic revisions accessible are provided.

Psix striaticeps (Dodd) (Hymenoptera, Scelionidae): an Old World parasitoid of stink bug eggs arrives in Florida, USA https://jhr.pensoft.net/article/76191/ Journal of Hymenoptera Research 87: 503-521

DOI: 10.3897/jhr.87.76191

Authors: Sarah Birkmire, Cory Penca, Elijah J. Talamas, Matthew R. Moore, Amanda C. Hodges

Abstract: Psix striaticeps (Dodd) is an egg-parasitoid wasp previously known only from the Old World. We report this species from twelve counties in Florida, which are the first records in the Western Hemisphere. It was collected in yellow cylinder traps and reared from the eggs of three stink bug species: Nezara viridula L., Chinavia marginata (Palisot de Beauvois), and Piezodorus guildinii (Westwood). A COI barcode analysis found a 100% match between the Floridian population and a specimen from South Africa. The prospects of using Ps. striaticeps as a biological control agent against exotic stink bugs are discussed.

DOI: 10.3897/jhr.87.75363

Authors: N. Rocío Rojas-Gálvez, Elijah Talamas, Marta V. Albornoz, M. Fernanda Flores, Wilson Barros-Parada, Alexandre Bout

Abstract: A parasitoid wasp, Gryon aetherium Talamas (Hymenoptera, Scelionidae), was reared from eggs of the invasive stink bug Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae) in Chile. The identification of G. aetherium, which is under study as a biological control agent, was made with morphological and molecular data in the context of a recent taxonomic treatment of this species. The presence of an adventive population of G. aetherium in South America has implications for biological control of B. hilaris in Chile, and other countries on the continent, where this stink bug may become a pest.

DOI: 10.3897/jhr.87.73778

Authors: Brian N. Hogg, Evelyne Hougardy, Elijah Talamas

Abstract: Bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), has become a major pest of cole crops (cabbage, broccoli, cauliflower, kale) in California since its arrival in 2008. In this study we documented parasitism of B. hilaris eggs at a highly infested site in northern California by deploying sentinel B. hilaris eggs and collecting naturally-laid B. hilaris eggs in the soil. Two parasitoids, Gryon aetherium Talamas (Hymenoptera, Scelionidae) and Ooencyrtus californicus Girault (Hymenoptera, Encyrtidae), emerged from sentinel eggs, but only G. aetherium was documented attacking eggs in the soil. Gryon aetherium is currently being assessed as a classical biological control agent for B. hilaris in California, and mating experiments showed that crosses between G. aetherium from Pakistan and California yielded viable female offspring. This report marks the first known record of G. aetherium in the USA, and further work should be conducted to assess the potential of this parasitoid for biological control of B. hilaris.

Deducing how tropical rhyssines (Hymenoptera, Ichneumonidae) mate from body measurements https://jhr.pensoft.net/article/71615/ Journal of Hymenoptera Research 86: 93-100

DOI: 10.3897/jhr.86.71615

Authors: Sanna Keronen, Ilari E. Sääksjärvi, Tapani Hopkins

Abstract: The biology of many Darwin wasp (Hymenoptera: Ichneumonidae) species is poorly known. Existing museum specimens can potentially be used to get information on e.g. how species live, what they eat, and what their life cycle is. One example of this is a 1991 study by Eggleton in which he measured some rhyssine (Ichneumonidae: Rhyssinae) species, and used the results to deduce how the species likely mate. We extend this work by measuring five tropical species. We found no evidence that the males of our species scramble for females before the females emerge, which matches what was hypothesised by Eggleton. Further measurements of more species would provide information on how other species mate, and field observations of mating rhyssines would help confirm that Eggleton’s method for deducing rhyssine mating strategies gives true results.

The paradox of the velvet-ant (Hymenoptera, Mutillidae) https://jhr.pensoft.net/article/68795/ Journal of Hymenoptera Research 84: 327-337

DOI: 10.3897/jhr.84.68795

Authors: Justin O. Schmidt, Li S. Schmidt, Deborah K. Schmidt

Abstract: Female diurnal velvet-ants are among the insects most strongly protected against predation. These protections include an exceedingly hard and tightly fitting integument, powerful legs and rapid running ability, aposematic color, aposematic warning stridulation, aposematic odor, and, most famously, legendarily powerful stings. Small to medium-sized velvet-ants were rarely injured or killed in tests against potential predators. Velvet-ant stings are painful, often exceedingly so, but have low toxicity or lethality and are of defensive value primarily by causing intense pain. Despite being well defended against predators they do not form night-time resting aggregations that might enhance mutual protection.

Extreme species density of bees (Apiformes, Hymenoptera) in the warm deserts of North America https://jhr.pensoft.net/article/60895/ Journal of Hymenoptera Research 82: 317-345

DOI: 10.3897/jhr.82.60895

Authors: Robert L. Minckley, William R. Radke

Abstract: Despite the long intertwined evolutionary histories of bees and plants, bee diversity peaks in the xeric areas of the eastern and western hemispheres and not the tropics, where plant diversity is greatest. Intensive sampling in the northeast Chihuahuan Desert of Mexico and the United States provide the first quantitative estimate of bee species richness where high diversity had been predicted in North America from museum records. We find that the density of bee species in a limited area of 16 km2 far exceeds any other site in the world and amounts to approximately 14% of the bee species described from the United States. Long-term studies of bees and other pollinators from areas that are minimally impacted by humans provide much-needed baseline data for studies of bees where human impacts are more severe and as climate change accelerates.

Cladistic analysis of Zethus Fabricius, 1804 (Hymenoptera, Vespidae): a new subgeneric classification https://jhr.pensoft.net/article/65760/ Journal of Hymenoptera Research 82: 253-283

DOI: 10.3897/jhr.82.65760

Authors: Rogério Botion Lopes, James M. Carpenter, Fernando Barbosa Noll

Abstract: Zethus is the largest genus in Vespidae with over 270 species. It is currently divided into four subgenera: Z. (Zethus), Z. (Zethoides), Z. (Zethusculus) and Z. (Madecazethus). While the last three are restricted to certain biogeographic areas, the first is spread through western and eastern hemispheres. Studies have shown possible phylogenetic incongruence regarding this current division and even raised the possibility of paraphyly in the genus. To evaluate this classification, morphological pasimony analyses under implied weights was carried out, examining external morphology and male genitalia. Analyses showed paraphyly of the genus under various “k” values and paraphyly of two subgenera. Ischnocoelia and Ctenochilus are lowered to subgenera of Zethus. Zethus (Madecazethus) is no longer restricted to Malagasy species and now includes those of the African continent as well. Zethus (Zethastrum) subg. nov. is defined for Oriental representatives. Z. (Zethus) is subdivided into three subgenera: Z. (Zethus), Z. (Didymogastra) and Z. (Wettsteinia). Zethus (Zethusculus) and Z. (Zethoides) are monophyletic and hold their status as subgenera. Three species-groups are Incertae sedis: Z. albopictus, Z. pallidus and Z. spinosus.

Checklists of the Hymenoptera of Canada, Alaska and Greenland – Introduction https://jhr.pensoft.net/article/60054/ Journal of Hymenoptera Research 82: 1-19

DOI: 10.3897/jhr.82.60054

Authors: Andrew M. R. Bennett

Abstract: The distribution of described, extant species of the insect order Hymenoptera recorded from northern North America will be published in a series of ten checklists. In total, 9250 species in 27 superfamilies and 84 families are recorded from Canada, the state of Alaska (USA) and Greenland (Denmark). Within northern North America, 8933 species are recorded in Canada (96.6% of the total species), Alaska has 1513 (16.4%) and Greenland has 205 (2.2%). Within Canada, Ontario is the province with the most species recorded (5322, 57.5% of all species in northern North America), followed by Quebec (4207, 45.5%) and British Columbia (4063, 43.9%). At the family level, Ontario has 82 of the 84 recorded families, Quebec has 76 and British Columbia has 71. The most species-rich superfamilies in northern North America are Ichneumonoidea (4438 species, 48.0% of the total); Apoidea (1438, 15.5%) and Chalcidoidea (1246, 13.5%). The largest families are Ichneumonidae (3201 species, 34.6% of the total), Braconidae (1237, 13.4%), Tenthredinidae (573, 6.2%), Eulophidae (379, 4.1%) and Pteromalidae (309, 3.3%). Overall species richness of the Hymenoptera in northern North America is compared with surveys in Russia, Germany, Finland and the British Isles.

A new species of Grotea Cresson, the first record of Labeninae (Hymenoptera, Ichneumonidae) in the Greater Antilles https://jhr.pensoft.net/article/59769/ Journal of Hymenoptera Research 81: 1-8

DOI: 10.3897/jhr.81.59769

Authors: Marissa Sandoval, Bernardo F. Santos

Abstract: Grotea ambarosa sp. nov. is described, illustrated and compared to currently described species of the genus. The new species is characterized mainly by having the mesosoma 2.9× as long as high; genal projection distinct and apically subquadrate; pleural carina distinct only anteriorly to anterior transverse carina; mesosoma almost entirely amber-orange and legs with complex dark brown and white marks. This is the first record of any labenine species for the Greater Antilles; the few distribution records elsewhere in the Caribbean Islands are reviewed and discussed in the context of the biogeography of Labeninae.

Amiseginae and Cleptinae from northeastern Brazil, with the description of four new species (Hymenoptera, Chrysididae) https://jhr.pensoft.net/article/60048/ Journal of Hymenoptera Research 81: 57-85

DOI: 10.3897/jhr.81.60048

Authors: Daercio A.A. Lucena, Eduardo A.B. Almeida, Fernando C.V. Zanella

Abstract: The diversity of two subfamilies of cuckoo wasps in northeastern Brazil is reviewed. Four new species are described and illustrated: Amisega boyi Lucena, sp. nov., A. sertaneja Lucena, sp. nov., and Duckeia dudui Lucena, sp. nov. (Amiseginae), and Cleptidea nordestina Lucena, sp. nov. (Cleptinae). These new species of Amisega and Duckeia represent the first records of both genera in the core zone of the Caatinga dry region, and they seem to be endemic to this portion of the region. The other two Amisega species previously recorded in northeastern Brazil are restricted to ecotone habitats between Caatinga and Atlantic forest. Cleptidea nordestina Lucena, sp. nov. (Cleptinae) is the most septentrional record for the fasciata species group in South America. With the present contribution, the total recorded diversity of Amiseginae and Cleptinae in northeastern Brazil is represented by the following species: A. boyi Lucena, sp. nov., A. flavipes Kimsey, 1987, A. sertaneja Lucena, sp. nov., A. similis Kimsey, 1987, and D. dudui Lucena, sp. nov. (Amiseginae), and C. nordestina Lucena, sp. nov. (Cleptinae).

Nesting ecology of the Pacific cicada killer, Sphecius convallis Patton (Hymenoptera, Crabronidae), in the Sonoran Desert https://jhr.pensoft.net/article/59206/ Journal of Hymenoptera Research 80: 177-191

DOI: 10.3897/jhr.80.59206

Authors: Joseph R. Coelho, Jon M. Hastings, Charles W. Holliday

Abstract: Factors affecting the ecology of a large population of Pacific cicada killers (Sphecius convallis) occupying a field of mine tailings in Ruby, AZ, were examined. Burrows were quite dense in certain areas around the periphery of the mine tailings, but were dispersed randomly within these areas. Approximately 1600 females (based on burrow counts) and 2500 males (based on mark-recapture) were recorded, yielding a total population estimate of 5000–6000 adults. Female wasps were able to dig much more rapidly in the mine tailings than their congeners S. speciosus in soils from PA, suggesting that the habitat suitability was a large factor in this robust population. Provisioning rate was comparatively slow, however, suggesting that cicada abundance in that year was not a contributor to the high population density. The presence of a sap-producing tree may have eased the energetic and thermoregulatory demands of the wasps. Although excavations revealed that the number of burrows and cells could easily maintain the population size, the lack of cicadas probably resulted instead in a population crash the following season.

The great greenbriers gall mystery resolved? New species of Aprostocetus Westwood (Hymenoptera, Eulophidae) gall inducer and two new parasitoids (Hymenoptera, Eurytomidae) associated with Smilax L. in southern Florida, USA https://jhr.pensoft.net/article/59466/ Journal of Hymenoptera Research 80: 71-98

DOI: 10.3897/jhr.80.59466

Authors: Michael W. Gates, Y. Miles Zhang, Matthew L. Buffington

Abstract: Aprostocetus smilax Gates & Zhang, sp. nov., is described from stem and leaf galls on Smilax havanensis Jacq. in southern Florida, USA. It is the third species of Aprostocetus Westwood known to induce plant galls. Two parasitoids of A. smilax are also described: Phylloxeroxenus smilax Gates & Zhang sp. nov. and Sycophila smilax Gates & Zhang, sp. nov. We conclude that A. smilax is the true gall inducer on Smilax L., and thus the host records of Diastrophus smilacis Ashmead and its inquiline Periclistus smilacis Ashmead, both from Smilax, are erroneous.

Hymenoptera functional groups’ shifts in disturbance gradients at Andean forests in Southern Ecuador https://jhr.pensoft.net/article/60345/ Journal of Hymenoptera Research 80: 1-15

DOI: 10.3897/jhr.80.60345

Authors: Marina Mazón, Ximena López, Oscar Romero

Abstract: Ecosystems under ecological restoration should be monitored in order to investigate if the ecosystem is being functionally recovered, especially in highly vulnerable biodiversity hotspots like Andean forests. Here we sampled Hymenoptera families in four Andean forest reserves above 1800 masl from Southern Ecuador, in three conservation levels in each forest: low (degraded), medium (10–15 years of recovery) and high (well-conserved forest). All Hymenoptera families were classified into four functional groups: predators, herbivores, pollinators and parasitoids. A total of 32 hymenopteran families were collected, with parasitoids clearly dominating in the samples. Family assemblages were not statistically different, neither in abundance nor family richness. Assemblages were more similar between them in the high and medium areas than in low conservation areas, where assemblages were very variable and showed a higher functional diversity in two of the reserves. The low presence of pollinators may be due to the high humidity during the sampling and the sampling method. Although some results are promising for the restoring trajectory, especially for parasitoids, we should keep in mind that this is at family level, so it would be interesting to know if these patterns persist at lower taxonomic levels.

First report and integrated analysis of two native Trissolcus species utilizing Bagrada hilaris eggs in California https://jhr.pensoft.net/article/57024/ Journal of Hymenoptera Research 80: 49-70

DOI: 10.3897/jhr.80.57024

Authors: Fatemeh Ganjisaffar, Elijah J. Talamas, Marie Claude Bon, Thomas M. Perring

Abstract: Surveys with sentinel eggs of Bagrada hilaris (Hemiptera: Pentatomidae) in southern California retrieved two parasitoids that were not previously known to be associated with this stink bug, Trissolcus hullensis and T. utahensis (Hymenoptera: Scelionidae). Molecular and morphological analysis of these specimens is used to modify the concept of T. utahensis and assess the factors that contribute to intraspecific variation. We provide an updated couplet to separate T. utahensis from a morphologically similar species, T. cosmopeplae.

Biological attributes of diapausing and non-diapausing Doryctobracon areolatus (Hymenoptera, Braconidae), a parasitoid of Anastrepha spp. (Diptera, Tephritidae) fruit flies https://jhr.pensoft.net/article/52269/ Journal of Hymenoptera Research 78: 41-56

DOI: 10.3897/jhr.78.52269

Authors: Jassmin Cruz-Bustos, Pablo Montoya, Gabriela Pérez-Lachaud, Javier Valle-Mora, Pablo Liedo

Abstract: Doryctobracon areolatus (Szépligeti), a solitary endoparasitoid native to the Neotropics, attacks eggs and early instar larvae of Anastrepha fruit flies, and can enter diapause under tropical and subtropical conditions. We aimed to test if biological attributes, such as size, flight ability, starvation resistance, longevity and fecundity of diapausing individuals differ from those of non-diapausing ones. Parasitoids were obtained from a laboratory colony reared on Anastrepha ludens (Loew) larvae. Parasitized host puparia were sorted in two cohorts according to their diapause condition. Developmental time from egg to adult ranged from 18 to 31 days in non-diapausing parasitoids, and 70 to 278 days for diapausing individuals. Pupal weight and adult measurements were higher in non-diapausing than in diapausing parasitoids. There were no differences in adult longevity, starvation resistance, and emergence between diapausing and non-diapausing wasps. Flight ability and fecundity rates were greater in the non-diapausing than in the diapause cohort. The proportion of female offspring was greater in the non-diapausing cohort (42.5%), whereas in the diapausing cohort the male offspring proportion was greater (62.4%). Both cohorts produced diapause offspring, but the non-diapausing cohort produced more (26.6%) than the diapausing one (9.1%). Maternal age had a significant effect on the proportion of diapause offspring: in 26 to 34 days old non-diapausing females, 78.9% of their offspring entered into diapause. These results confirmed that diapause affects the biological attributes of D. areolatus. The observed differences contribute to better understand the diapause influence on the colonization and rearing process of this species and its use as biocontrol agent.

Sampling of parasitoid Hymenoptera: influence of the height on the ground https://jhr.pensoft.net/article/54309/ Journal of Hymenoptera Research 78: 19-31

DOI: 10.3897/jhr.78.54309

Authors: Ricardo Chan-Canché, Horacio Ballina-Gómez, Jorge Leirana-Alcocer, Santiago Bordera, Alejandra González-Moreno

Abstract: Parasitoid hymenopterans are a highly diverse group of insects; therefore, the choice of an adequate sampling method becomes important to achieve a representative species richness of a site. The aim of this work is to evaluate the size and diversity of parasitoids in relation to the height of the Malaise trap placement above the ground of a low deciduous forest from Yucatan, Mexico. Parasitoids were collected from September to October 2015, using three Malaise traps at ground level and other three located right above the others, leaving no space between them, at a height of 1.5 m. The collected specimens were identified at family level. A total of 4083 parasitoids belonging to 31 families were collected, representing 93% of the sample’s completeness, according to Jack 1 estimator; with differences in richness and abundance between trap heights according to rarefaction and fixed effects multifactorial ANOVA, respectively. Bethylidae, Braconidae and Ichneumonidae were the most abundant families. Besides, when analyzing the differences of each family by separate, there were significant results for Bethylidae, Diapriidae and Ichneumonidae with more individuals in the traps at ground level than in the raised ones. In a further analysis, the effect of body size on the capture height was observed. The specimens of larger size belonging to the families Bethylidae, Sphecidae, Sclerogibbidae and Evaniidae were more collected at ground level, on the other hand, the larger sized Ichneumonidae were collected at raised level.

Authors: Paul K. Abram, Audrey E. McPherson, Robert Kula, Tracy Hueppelsheuser, Jason Thiessen, Steve J. Perlman, Caitlin I. Curtis, Jessica L. Fraser, Jordan Tam, Juli Carrillo, Michael Gates, Sonja Scheffer, Matthew Lewis, Matthew Buffington

Abstract: We report the presence of two Asian species of larval parasitoids of spotted wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), in northwestern North America. Leptopilina japonica Novkovic & Kimura and Ganaspis brasiliensis (Ihering) (Hymenoptera: Figitidae) were found foraging near and emerging from fruits infested by D. suzukii at several locations across coastal British Columbia, Canada in the summer and fall of 2019. While G. brasiliensis was found in British Columbia for the first time in 2019, re-inspection of previously collected specimens suggests that L. japonica has been present since at least 2016. Additionally, we found a species of Asobara associated with D. suzukii in British Columbia that is possibly Asobara rufescens (Förster) (known only from the Palearctic Region) based on COI DNA barcode data. These findings add to the list of cases documenting adventive establishment of candidate classical biological control agents outside of their native ranges. The findings also illustrate the need for revisiting species concepts within Asobara, as well as host and geographic distribution data due to cryptic and/or misidentified species.

Abstract: In Trinidad, West Indies the social wasps Angiopolybia pallens and Polybia rejecta come to foam nests of the frog Engystomops pustulosus, where they prey on eggs and tadpoles. Frog offspring in early-stage foam nests appear to be almost immune to predation by the wasps, but they become more vulnerable as the nests age and lose definition.

Abstract: Sampling of crapemyrtle trees (Lagerstroemia L.) in central Texas yielded the discovery of an invasive scale pest, Lopholeucaspis japonica Cockerell, and its parasitoid natural enemy, Marlattiella prima Howard. These discoveries expand the known range of both the scale insect and the parasitoid wasp in the United States. Marlattiella prima was not recovered in the absence of L. japonica. Of the two counties sampled, Brazos County yielded 26 M. prima individuals and Tarrant County yielded neither M. prima nor L. japonica.

An updated checklist of the bees (Hymenoptera, Apoidea, Anthophila) of Pennsylvania, United States of America https://jhr.pensoft.net/article/49622/ Journal of Hymenoptera Research 77: 1-86

DOI: 10.3897/jhr.77.49622

Authors: Shelby Kerrin Kilpatrick, Jason Gibbs, Martin M. Mikulas, Sven-Erik Spichiger, Nancy Ostiguy, David J. Biddinger, Margarita M. Lopez-Uribe

Abstract: Checklists provide information about the species found in a defined region and serve as baselines for detecting species range expansions, contractions, or introductions. Bees are a diverse and important group of insect pollinators. Although some bee populations are declining, these patterns are difficult to document and generalize due to a lack of long-term studies for most localities. Documenting the diversity of wild bee communities is critical for assessing pollination services, community ecology, and geographical and temporal changes in distribution and density. Here, an updated checklist of the bees of the Commonwealth of Pennsylvania, USA, is presented. Since the first checklist was published (2010; 372 species), thousands of additional specimens from the state have been collected and databased, new species have been described in the region, and the taxonomic status of some species have changed. Specimen data from insect collections, databases, scientific literature, and unpublished records were compared to the original checklist. Seventy-nine new state species records – including 49 first-time reports – representing five of the six bee families in North America, were documented resulting in a total of at least 437 bee species reported from Pennsylvania. We highlight new county records and species persistence details. Our list includes a total of 23 exotic species and at least five species of conservation concern. Lists of species excluded from the state checklist and species anticipated to occur in Pennsylvania are also included. This checklist provides baseline data for researchers and the public. The benefits of insect collections, specimen databases, determination and voucher labels, and georeferencing to biodiversity studies and other aspects of biological research are also discussed.

Two new species of Ooencyrtus (Hymenoptera, Encyrtidae), egg parasitoids of the bagrada bug Bagrada hilaris (Hemiptera, Pentatomidae), with taxonomic notes on Ooencyrtus telenomicida https://jhr.pensoft.net/article/48004/ Journal of Hymenoptera Research 76: 57-98

DOI: 10.3897/jhr.76.48004

Authors: Serguei V. Triapitsyn, Sharon A. Andreason, Nancy Power, Fatemeh Ganjisaffar, Lucian Fusu, Chrysalyn Dominguez, Thomas M. Perring

Abstract: In support of a biological control program in California, USA, against the bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), an invasive pest of Asian origin, colonies of two species of Ooencyrtus Ashmead (Hymenoptera, Encyrtidae) are maintained using B. hilaris eggs as host. One of them, Ooencyrtus mirus Triapitsyn & Power, sp. nov., is of Pakistani origin. It displays natural preference for bagrada bug eggs and is being evaluated in quarantine as a candidate for classical biological control. The other, Ooencyrtus lucidus Triapitsyn & Ganjisaffar, sp. nov., appears to be native to California, and we believe it switched to B. hilaris from native pentatomid hosts. Both new species are described and illustrated, as is the Old World species Ooencyrtus telenomicida (Vassiliev), for which a neotype is designated. The presented morphometric evidence as well as mitochondrial and nuclear ribosomal DNA sequence data separate Ooencyrtus mirus from O. telenomicida. A lectotype is designated for Ooencyrtus californicus Girault from California, which is morphologically similar to O. lucidus.

Status and potential distribution of the Asian carpenter bee, Xylocopa appendiculata Smith (Apidae, Xylocopini), in the United States https://jhr.pensoft.net/article/49518/ Journal of Hymenoptera Research 76: 99-111

DOI: 10.3897/jhr.76.49518

Authors: Allan H. Smith-Pardo, Glenn A. Fowler, Sunil Kumar

Abstract: We update the geographical distribution for Xylocopa appendiculata Smith, from eastern Asia, which was first reported from the United States of America (USA) in 2013. After the publication by Dahlberg et al. (2013), there have been more sightings supporting the establishment of X. appendiculata in northern California. We used plant hardiness zones and maximum entropy (Maxent) modeling to estimate the potential distribution of X. appendiculata in the USA using specimen data from multiple occurrences (confirmed data from literature, museum specimens and validated data from Discover Life.org and iNaturalist.org). We include images and a list of diagnostic features for the identification of the subgenus Alloxylocopa Hurd and Moure and the species X. appendiculata so that it can be identified and reported to corresponding state or federal authorities, if necessary.

Authors: Erin Krichilsky, Álvaro Vega-Hidalgo, Kate Hunter, Callum Kingwell, Chelsey Ritner, William Wcislo, Adam Smith

Abstract: Gynandromorphy is an anomaly that results in an organism phenotypically expressing both male and female characteristics. Here we describe the first gynandromorph of the bee species Megalopta amoena (Spinola, 1853) (Halictidae, Augochlorini) and the second record of this anomaly within the genus Megalopta. Additionally, we analyzed the bee’s circadian rhythm, which has never before been quantified for a gynandromorph. The gynandromorph showed a deviant activity pattern; it was intermediate between that of the male and female M. amoena. Our results imply that the brains of bilateral gynandromorphs may have mixed sex-specific signaling. Based on four days of recording, the gynandromorph circadian rhythm was shifted earlier in the day relative to the male and female M. amoena, and it exhibited intensity similar to the female.

The need for long-term management solutions for H. halys has driven studies on augmentative and classical biological control of this species, especially by its egg parasitoids. Numerous investigations in Asia, USA, and Europe on native and exotic egg parasitoids of H. halys, and the effects on non-target pentatomids, have improved the global knowledge of parasitoid-host relationships, uncovered new associations, and led to the discovery of new species. This trend continues with Acroclisoides sinicus, a pteromalid that was described in the 1980’s from Asia. In this work we report recent findings of this species in North America and Europe. Moreover, we propose that Acroclisoides solus syn. nov., a species described originally from the USA, is conspecific with A. sinicus based on morphological and molecular analysis.

Plant associations for three sawfly species (Hymenoptera, Tenthredinidae) in the Pacific Northwest https://jhr.pensoft.net/article/46795/ Journal of Hymenoptera Research 74: 27-33

DOI: 10.3897/jhr.74.46795

Authors: Quinlyn Baine, Chris Looney

Abstract: Plant associations are newly recorded for three tenthredinid species in the Pacific Northwest. A single Monardis pulla D.R. Smith, 1969 emerged from a chamber inside a cynipid gall on Rosa nutkana C. Presl. (Rosaceae). This is the first plant association record for M. pulla. Two Aphilodyctium fidum (Cresson, 1880) emerged from a stem and cynipid gall of Rosa rugibinosa Linnaeus, 1758, respectively. Several Rhogogaster lateraria (Cresson, 1880) eggs were discovered on Castilleja sp., which has no previously recorded sawfly associations.

Flower use by late nineteenth-century orchid bees (Eufriesea surinamensis, Hymenoptera, Apidae) nesting in the Catedral Basílica Santa María la Antigua de Panamá https://jhr.pensoft.net/article/39191/ Journal of Hymenoptera Research 74: 65-81

DOI: 10.3897/jhr.74.39191

Authors: Paola Galgani-Barraza, Jorge Enrique Moreno, Sofia Lobo, Wendy Tribaldos, David W. Roubik, William T. Wcislo

Abstract: A recent restoration of the Basilica Cathedral in Casco Viejo, Panamá, revealed that prior to 1871–1876 female orchid bees (Eufriesea surinamensis) built large nesting aggregations high above the main altar, based on physical evidence dating to a nineteenth-century restoration. Bees constructed cells in approximately 120 clusters in six different aggregations on the reredos (“altarpiece”). Palynological analyses of cell contents showed that bees visited 48 species of plants, representing 43 genera and 23 families. Contents of bee cells reflect elements of floristic diversity surrounding Panama City that are seen in historical contemporaneous photographs of the nesting site and environs.

DNA barcoding of rhopalosomatid larvae reveals a new host record and genetic evidence of a second species of Rhopalosoma Cresson (Hymenoptera, Rhopalosomatidae) in America north of Mexico https://jhr.pensoft.net/article/38276/ Journal of Hymenoptera Research 74: 35-46

DOI: 10.3897/jhr.74.38276

Authors: Lance A. Miller, Torie D. Benefield, Sarah A. Lounsbury, Volker Lohrmann, Jeremy D. Blaschke

Abstract: Rhopalosomatidae are unusual wasps whose larvae develop as ectoparasitoids on crickets. In America north of Mexico, three genera and six species are recognized. Host species are known only for Rhopalosoma nearcticum Brues and include Hapithus agitator Uhler, H. brevipennis (Saussure), and H. saltator (Uhler) (Gryllidae: Hapithinae). Here we report a new host species: the Anaxipha exigua (Say) species-group (Trigonidiidae: Trigonidiinae) discovered by barcoding nine rhopalosomatid larvae collected from Cypress Grove Nature Park, Jackson, Tennessee. Rhopalosoma nearcticum is currently the only documented species of Rhopalosoma Cresson in America north of Mexico, but our phylogenetic analyses recovered two genetically distinct clades of Rhopalosoma and thus reveal the presence of at least two species of Rhopalosoma in America north of Mexico.

Molecular phylogeny of Trissolcus wasps (Hymenoptera, Scelionidae) associated with Halyomorpha halys (Hemiptera, Pentatomidae) https://jhr.pensoft.net/article/39563/ Journal of Hymenoptera Research 73: 201-217

DOI: 10.3897/jhr.73.39563

Authors: Elijah J. Talamas, Marie-Claude Bon, Kim A. Hoelmer, Matthew L. Buffington

Abstract: As the brown marmorated stink bug (Halyomorpha halys) has spread across the Northern Hemisphere, research on its egg parasitoids has increased accordingly. These studies have included species-level taxonomy, experimental assessments of host ranges in quarantine, and surveys to assess parasitism in the field. We here present a molecular phylogeny of Trissolcus that includes all species that have been reared from live H. halys eggs. Species-group concepts are discussed and revised in the light of the phylogenetic analyses. The analyses indicate that the ability to successfully parasitize H. halys eggs is not phylogenetically constrained, but the most effective parasitoids are all found in the flavipes species group.

Scelionidae (Hymenoptera) parasitizing eggs of Bagrada hilaris (Hemiptera, Pentatomidae) in Mexico https://jhr.pensoft.net/article/36654/ Journal of Hymenoptera Research 73: 143-152

DOI: 10.3897/jhr.73.36654

Authors: Moisés Felipe-Victoriano, Elijah J. Talamas, Sergio R. Sánchez-Peña

Abstract: The painted bug or bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae), is a key pest of crops in the family Brassicaceae. In this work, three species of Scelionidae (Hymenoptera) are reported for the first time as parasitoids of painted bug eggs in Mexico, at Saltillo, state of Coahuila: Gryon myrmecophilum (Ashmead), Telenomus podisi Ashmead and Trissolcus basalis (Wollaston). This is also the first report of a species of the widespread genus Telenomus as an egg parasitoid of B. hilaris outside of India. Total percent parasitism, high resolution images, and CO1 sequences are provided for each species. In the future, research in Mexico should be carried out on parasitoid species presented in this work to determine their potential as biological control agents and the feasibility of augmentative, classical or inoculative biocontrol strategies for integrated pest management.

Paratelenomus anu Rajmohana, Sachin & Talamas (Hymenoptera, Scelionidae): description and biology of a new species of phoretic egg parasitoid of Megacopta cribraria (Fab.) (Hemiptera, Plataspidae) https://jhr.pensoft.net/article/34262/ Journal of Hymenoptera Research 73: 103-123

DOI: 10.3897/jhr.73.34262

Authors: Keloth Rajmohana, James P. Sachin, Elijah J. Talamas, Mukundan S. Shamyasree, S. K. Jalali, Ojha Rakshit

Abstract: Paratelenomus anu Rajmohana, Sachin & Talamas, sp. nov. (Hymenoptera: Scelionidae) is an egg parasitoid of the kudzu bug, Megacopta cribraria (Fab.) (Hemiptera: Plataspidae). It is morphologically and genetically distinct from P. saccharalis (Dodd), a well-known egg parasitoid of the same host. Paratelenomus anu is here described from India and diagnosed from other species of Paratelenomus Dodd. This parasitoid can be reared easily, has high rates of parasitism, and thus may be significant for the biological control of M. cribraria. Phoresy is documented in P. anu and provides the first known example of this behavior in Paratelenomus. Paratelenomus longus (Kozlov & Lê) syn. nov. and P. mangrovus Rajmohana & Narendran, syn. nov. are treated as junior synonyms of P. tetartus (Crawford), and P. obtusus (Lê) syn. nov. is treated as a junior synonym of P. saccharalis.

A review and updated classification of pollen gathering behavior in bees (Hymenoptera, Apoidea) https://jhr.pensoft.net/article/32671/ Journal of Hymenoptera Research 71: 171-208

DOI: 10.3897/jhr.71.32671

Authors: Zachary M. Portman, Michael C. Orr, Terry Griswold

Abstract: Pollen is the primary protein and nutrient source for bees and they employ many different behaviors to gather it. Numerous terms have been coined to describe pollen gathering behaviors, creating confusion as many are not clearly-defined or overlap with existing terms. There is a need for a clear yet flexible classification that enables accurate, succinct descriptions of pollen gathering behaviors to enable meaningful discussion and comparison. Here, we classify the different pollen gathering behaviors into two main classes: active and incidental pollen collection. Active pollen collection is subdivided into six behaviors: scraping with the extremities, buzzing, rubbing with the body and/or scopae, rubbing with the face, tapping, and rasping. In addition to the active and incidental pollen gathering behaviors, many bees have an intermediate step in which they temporarily accumulate pollen on a discrete patch of specialized hairs. Each behavior is described and illustrated with video examples. Many of these behaviors can be further broken down based on the variations found in different bee species. Different species or individual bees mix and match these pollen collecting behaviors depending on their behavioral plasticity and host plant morphology. Taken together, the different behaviors are combined to create complex behavioral repertoires built on a foundation of simple and basic steps. This classification sets the groundwork for further research on various topics, including behavioral plasticity in different species, comparisons between generalists and specialists, and the relative effectiveness of different pollen gathering behaviors.

Natural enemies of the oil-collecting bee Centris analis (Fabricius, 1804) with notes on the behavior of the cleptoparasite Coelioxys nigrofimbriata Cockerell, 1919 (Hymenoptera, Apidae) https://jhr.pensoft.net/article/33042/ Journal of Hymenoptera Research 70: 1-16

DOI: 10.3897/jhr.70.33042

Authors: Daniele Regina Parizotto

Abstract: This work presents a review of natural enemy species associated with Centris analis and summarizes the available information on life history, behavior, diversity, and specialization of these taxa. Records include over 20 species in ten genera from seven distinct families of Hymenoptera, Diptera and Coleoptera. These species are cleptoparasites or parasitoids of immature stages or adults. Some species seem to be occasional parasitoids, while others seem to be more frequent and responsible for significant mortality rates of immatures in nests. Three families of Hymenoptera represent the majority of natural enemy taxa found in C. analis nests: Apidae, Chrysididae, and Leucospidae. The most frequent parasitoid reared from nests was the wasp Leucospis cayennensis Westwood, followed by cleptoparasitic bee species of the genus Coelioxys Latreille. Vouchers of trap nest studies are identified for the first time and refer to Coelioxys nigrofimbriata Cockerell, which seems to have a strong association with nests of C. analis. Further direct observation notes about biology and behavior of C. nigrofimbriata are also provided.

DOI: 10.3897/jhr.70.35555

Authors: Jose Fernandez-Triana

Abstract: The genus Promicrogaster (Hymenoptera, Braconidae, Microgastrinae) in North America is revised and seven new species are described: floridakeys, gainesvillensis, huachuca, jaymeae, madreanensis, rondeau and virginianus. All but one have so far been found in protected areas of Canada and the USA, with two species collected at rather high altitudes of over 1,600 m.a.s.l. (Arizona, southwestern USA), whereas the other five were found in Eastern North America (southern Ontario and several USA states) at relatively lower altitudes (less than 150 m.a.s.l.). A key to all 31 described species in North and Meso America is provided. A species from Costa Rica previously described in Promicrogaster is here transferred to a different genus as Hypomicrogaster pablouzagai (Fernández-Triana & Boudreault, 2016), comb. nov.

The ants of Ohio (Hymenoptera, Formicidae): an updated checklist https://jhr.pensoft.net/article/35207/ Journal of Hymenoptera Research 70: 65-87

DOI: 10.3897/jhr.70.35207

Authors: Kaloyan Ivanov

Abstract: I update the last published list of Ohio ants to include 26 new species records and 38 name changes in species already on the list based on literature records, institutional collections, and contemporary collections made by the author or colleagues. At present, 143 species and morphospecies representing 30 native and 5 exotic genera and 7 subfamilies have been recorded for the state. Another seven species are removed from the Ohio ant fauna as they represent distribution anomalies, or are based on erroneous records. Known distribution data suggest that there is still a considerable potential for the discovery of more ant taxa in Ohio.
