Authors: Duk-Young Park, Seunghwan Lee

Abstract: The genus Plutarchia is discovered in the Palearctic region for the first time. In this study, we report a newly described and newly recorded species from South Korea: P. fuscipennata sp. nov., and P. malabarica Narendran & Padmasenan, 1990, respectively. The host association of Plutarchia malabarica reared from leaf-miner flies (Diptera: Agromyzidae) attacking the seeds of Pueraria lobata (Willd.) Ohwi (Fabaceae) has been unknown until now. A key to the South Korean species and descriptions of the new species are also provided.

Description and mitochondrial genome sequencing of a new species of inquiline gall wasp, Synergus nanlingensis (Hymenoptera, Cynipidae, Synergini), from China https://jhr.pensoft.net/article/119433/ Journal of Hymenoptera Research 97: 105-126

DOI: 10.3897/jhr.97.119433

Authors: Yu-Bo Duan, Yan-Jie Wang, Dao-Hong Zhu, Yang Zeng, Xiu-Dan Wang

Abstract: A new species of inquiline gall wasp, Synergus nanlingensis Wang & Zeng, sp. nov., which was reared from galls on Castanopsis eyrei Tutch (Fagaceae) collected in Guangdong Province, China, is described and illustrated herein along with its mitochondrial genome. The mitogenome of S. nanlingensis is 16,604 base pairs in length and comprises 37 genes, which is typical of mitogenomes. One large control region was detected in the S. nanlingensis mitogenome, which differed from that reported for other Cynipidae species. Similar to other Cynipidae species, S. nanlingensis has the same four common gene rearrangement events; however, it shows some differences, as follows: trnS1 is downstream of Cytb; trnS2 is upstream of nad1; and trnC is downstream of rrnS. Phylogenetic analysis using COI, CytB, and 28S-D2 sequences confirmed that S. nanlingensis is a distinct species belonging to the genus Synergus Hartig.

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.

A new small carder bee species from the eastern Canary Islands (Hymenoptera, Megachilidae, Anthidiini) https://jhr.pensoft.net/article/111550/ Journal of Hymenoptera Research 96: 983-1015

DOI: 10.3897/jhr.96.111550

Authors: Nicolas J. Vereecken, Carlos Ruiz, Leon Marshall, Mónica Pérez-Gil, Jean-Marc Molenberg, Bernhard Jacobi, Francisco La Roche, Jessica R. Litman

Abstract: Recent field surveys in the eastern Canary Islands (Spain), followed by contributions of new occurrence records through the citizen science platform iNaturalist.com and the social media photo repository Flickr.com have revealed the presence of an overlooked small carder bee species (genus Pseudoanthidium Friese (Megachilidae: Anthidiini)) on the islands of Lanzarote and Fuerteventura. Here, we combined morphology, DNA barcodes (mitochondrial cytochrome c oxidase subunit I, COI) and ecological data (distribution, altitudinal ranges and environmental niche classification) to describe this species as Pseudoanthidium (Pseudoanthidium) jacobii sp. nov. We provide an illustrated description along with diagnostic morphological characters to separate it from P. (P.) canariense (Mavromoustakis, 1954), the only other congeneric species known from the neighbouring islands of La Gomera, Tenerife and Gran Canaria and from which it is separated by a genetic distance of 2.7%. We also evaluated the extent of shared environmental niche space among the two Pseudoanthidium species, and our results show a significant difference in elevation range as well as a very small (less than 1%) overlap between the modelled climatic niche of P. jacobii and that of P. canariense. Given the extremely restricted geographic distribution and the fragile and isolated nature of the habitat and host plants of this new island endemic species, we assign it an IUCN conservation status of “EN” (endangered) and discuss avenues for future research on the ecology and conservation of wild bees in the Canary Islands and neighbouring regions.

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.

At the dawn of megadiversity – Protoitidae, a new family of Chalcidoidea (Hymenoptera) from Lower Cretaceous Lebanese amber https://jhr.pensoft.net/article/105494/ Journal of Hymenoptera Research 96: 879-924

DOI: 10.3897/jhr.96.105494

Authors: Jonah M. UImer, Petr Janšta, Dany Azar, Lars Krogmann

Abstract: The earliest representatives of Chalcidoidea are described from Barremian age Early Cretaceous Lebanese amber and classified in Protoitidae Ulmer & Krogmann, fam. nov. (Hymenoptera: Chalcidoidea). Protoitidae exhibits a high morphological diversity of the terminal metasomal tergum which may indicate a broad spectrum of oviposition capabilities and the ability to occupy a diverse range of ecological niches. Protoitidae comprises two genera, Protoita Ulmer & Krogmann, gen. nov., and Cretaxenomerus Nel & Azar, 2005 based on C. jankotejai Nel & Azar, 2005, which is transferred from Scelionidae (Hymenoptera: Platygastroidea) to Protoitidae. Together, 10 new species, all by Ulmer and Krogmann, are described in the two included genera–Protoita bidentata, P. istvani, P. noyesi, P. petersi, Cretaxenomerus brevis, C. curvus, C. deangelis, C. mirari, C. tenuipenna, and C. vitreus. Keys to the genera and species of Protoitidae are provided. In addition, we examine the postulated plesiomorphies and apomorphies within Chalcidoidea with respect to the fossil record, and provide additional hypotheses on their biogeographic origins.

Two new species of the genus Cryptopimpla Taschenberg (Hymenoptera, Ichneumonidae, Banchinae) with an updated key to African species https://jhr.pensoft.net/article/104038/ Journal of Hymenoptera Research 96: 667-696

DOI: 10.3897/jhr.96.104038

Authors: Terry Reynolds, Simon van Noort

Abstract: A revised illustrated key to Afrotropical species of the genus Cryptopimpla Taschenberg is provided, with the inclusion of two new South African species, C. orenji Reynolds & van Noort, sp. nov. and C. hoerikwagga Reynolds & van Noort, sp. nov., which are described and illustrated. The recovery of the first female specimens of Cryptopimpla goci Reynolds & van Noort in samples from Fernkloof and Grootbos nature reserves, and subsequent morphological reassessment of generic affinity based on female characters, no longer supports the placement of this species in Cryptopimpla. The transfer of C. goci to Lissonota Gravenhorst is proposed here: Lissonota goci (Reynolds & van Noort), comb. nov., and the female is described. New Afrotropical distributional records for the previously described Cryptopimpla species are presented and notes on the distribution and diversification of the species are also provided. Online interactive Lucid keys to the 11 Afrotropical Cryptopimpla species are available at: http://www.waspweb.org.

Two new Hoplitis species of the subgenus Hoplitis Klug, 1807 (Hymenoptera, Megachilidae) and the nesting biology of H. astragali sp. nov. in Dagestan https://jhr.pensoft.net/article/109255/ Journal of Hymenoptera Research 96: 641-656

DOI: 10.3897/jhr.96.109255

Authors: Alexander V. Fateryga, Andreas Müller, Maxim Yu. Proshchalykin

Abstract: Hoplitis astragali sp. nov., a member of the H. monstrabilis species group, and H. dagestanica sp. nov., a member of the H. adunca species group, are described. The former species is known from Dagestan in Russia, Azerbaijan, and Turkmenistan, the latter only from Dagestan. Nests of H. astragali are described. Females of this species excavated burrows in a vertical clay cliff, but sometimes chose a horizontal surface for nest excavation, particularly at the entrance of old burrows of Xylocopa olivieri (Apidae). The nest burrows of H. astragali were either sub-vertical or sub-horizontal. The nests were composed of one to three brood cells, an empty vestibule in front of the outermost cell, and a closing plug at the nest entrance made of moistened mud. The inner surface of the cells was covered with a thin wall composed of compact soil, most probably built by the female bee after cell excavation. The pollen loaf was very liquid and had a spherical shape. The egg was deposited on its top. The cocoon consisted of a single thin layer, which uniformly covered the whole inner surface of the cell. There was one generation per year. The prepupae hibernated. Sapyga caucasica (Sapygidae) was recorded in the nests as a kleptoparasite. Both females and males of H. astragali exclusively visited flowers of two species of the genus Astragalus (Fabaceae).

European cuckoo bees of the tribe Dioxyini (Hymenoptera, Megachilidae): distribution, annotated checklist and identification key https://jhr.pensoft.net/article/104957/ Journal of Hymenoptera Research 96: 599-628

DOI: 10.3897/jhr.96.104957

Authors: Petr Bogusch

Abstract: Altogether, ten species of cuckoo bees of the tribe Dioxyini have been recorded from Europe, with two species distributed widely in the continent while others are restricted in distribution to only one or several countries in southern Europe. These ten representatives are classified into five genera: Aglaoapis, Dioxys, Ensliniana, Metadioxys and Paradioxys. Dioxys atlanticus is reclassified from a subspecies to a valid species, and new occurrence records of this species are reported. New synonymy is established for Dioxys cinctus = D. montana syn. nov. The distribution, morphology, ecology and hosts of all species were reviewed from both published and unpublished sources. New red-list categories for each species were created according to the new records of occurrence. An identification key including all ten species and photographs of their whole bodies and main identification characteristics was prepared, and distribution maps for all species were created.

The genus Andrena Fabricius, 1775 in the Iberian Peninsula (Hymenoptera, Andrenidae) https://jhr.pensoft.net/article/101873/ Journal of Hymenoptera Research 96: 241-484

DOI: 10.3897/jhr.96.101873

Authors: Thomas J. Wood

Abstract: The Iberian Peninsula is a global hotspot for bee diversity due to its large number of different habitats, particularly Mediterranean scrubland, mountains, and hot and cold steppe. In line with its status as a hotspot of bee diversity, the peninsula hosts a very large Andrena fauna, which despite progress in recent years remains incompletely studied, particularly with reference to genetic investigation. Here the Iberian Andrena fauna is comprehensively revised, resulting in a total of 228 recorded species. Numerous taxonomic changes are necessary following inspection of museum specimens, type material, and genetic investigation. The following subgenera are described: Pruinosandrena subgen. nov., containing six taxa previously placed in the subgenus Campylogaster Dours, 1873, and Blandandrena subgen. nov., Bryandrena subgen. nov., Limbandrena subgen. nov., and Ovandrena subgen. nov., containing one, one, one, and four taxa previously placed in the subgenus Poliandrena Warncke, 1968. Andrena (Limbandrena) toelgiana Friese, 1921 syn. nov. is synonymised with A. (Limbandrena) limbata Eversmann, 1852. The current lectotype of A. (Micrandrena) obsoleta Pérez, 1895 was incorrectly designated by Warncke; the taxon differs from A. obsoleta sensu Warncke, belonging instead to a taxon within the A. mariana Warncke, 1968 complex. A new lectotype is designated for A. obsoleta sp. resurr. from Algeria, and A. mariana solda Warncke, 1974 syn. nov. is synonymised with it; A. (Micrandrena) alma Warncke, 1975 stat. nov., A. (Micrandrena) mica Warncke, 1974 stat. nov., and A. (Micrandrena) tenostra Warncke, 1975 stat. nov. are raised to species status. Andrena (Truncandrena) abunda Warncke, 1974 stat. nov., A. (Micrandrena) lecana Warncke, 1975 stat. nov., A. (Pruinosandrena) parata Warncke, 1967 stat. nov., A. (Micrandrena) pauxilla Stöckhert, 1935 sp. resurr., A. (Pruinosandrena) succinea Dours, 1872 sp. resurr., and A. (Notandrena) varuga Warncke, 1975 stat. nov. are also returned or elevated to species status. A lectotype is designated for A. (Euandrena) lavandulae Pérez, 1902 sp. resurr. which is returned to species status, and A. (Euandrena) impressa Warncke, 1967 syn. nov. is synonymised with it. Andrena (Truncandrena) nigropilosa Warncke, 1967 stat. nov. is elevated to species status, and A. (Truncandrena) truncatilabris espanola Warncke, 1967 syn. nov. is synonymised with it as a junior subjective synonym. A lectotype is designated for A. (Melandrena) vachali Pérez, 1895; A. (Melandrena) creberrima Pérez, 1895 syn. nov. and A. (Melandrena) vachali syn. nov. are synonymised with A. (Melandrena) discors Erichson, 1841, and Andrena (Melandrena) hispania Warncke, 1967 syn. nov. is synonymised with A. (Melandrena) morio Brullé, 1832. Andrena (Pruinosandrena) mayeti Pérez, 1895 syn. nov. is newly synonymised with A. (Pruinosandrena) caroli Pérez, 1895 and A. (incertae sedis) setosa Pérez, 1903 syn. nov. is newly synonymised with A. (incertae sedis) ranunculorum Morawitz, 1877. Andrena (Simandrena) cilissaeformis Pérez, 1895 sp. resurr. is returned to species status, and is the correct name for A. (Simandrena) breviscopa auctorum. Andrena (incertae sedis) breviscopa Pérez, 1895 is returned to synonymy with A. (incertae sedis) numida Lepeletier, 1841, and A. (incertae sedis) inconspicua Morawitz, 1871 is newly synonymised syn. nov. with A. numida. Andrena (Euandrena) isolata sp. nov. and A. (Micrandrena) ortizi sp. nov. are described from the Sierra Nevada (Granada), A. (Truncandrena) ghisbaini sp. nov. is described from Málaga province, and A. (Avandrena) juliae sp. nov. is described from Cádiz province. The males of A. (Micrandrena) alma and A. (?Euandrena) ramosa Wood, 2022 are described. Additional lectotypes are designated for A. (Plastandrena) asperrima Pérez, 1895, A. (Plastandrena) atricapilla Pérez, 1895, A. (Aenandrena) hystrix Schmiedeknecht, 1883, A. (Pruinosandrena) lanuginosa Spinola, 1843, A. (Notandrena) ranunculi Schmiedeknecht, 1883, and A. (Euandrena) symphyti Schmiedeknecht, 1883. Neotypes are designated for A. (Chlorandrena) boyerella Dours, 1872, A. (Notandrena) griseobalteata Dours, 1872, A. (Taeniandrena) poupillieri Dours, 1872, A. (Pruinosandrena) succinea Dours, 1872, and A. (incertae sedis) numida Lepeletier, 1841. Type photographs and diagnostic characters are presented in each case, as well as new dietary information for understudied species. Finally, an identification key is presented in order to facilitate future research on this hyper-diverse genus in one of their global diversity hotspots, and current and future research perspectives for Iberian Andrena are discussed.

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.

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.

Laotris luzulae (Hymenoptera, Braconidae, Alysiinae, Dacnusini), a new species from the southwest of England https://jhr.pensoft.net/article/97490/ Journal of Hymenoptera Research 95: 73-83

DOI: 10.3897/jhr.95.97490

Authors: H. Charles J. Godfray

Abstract: Laotris luzulae Godfray, sp. nov. is described in the small genus Laotris Nixon, 1943, (Braconidae, Alysiinae, Dacnusini) from five specimens reared from Cerodontha silvatica (Groschke, 1957) (Diptera, Agromyzidae) mining Luzula sylvatica (Huds.) Gaudin (Juncaceae) in Devon and Gloucestershire in the southwest of Great Britain. Six further specimens from Somerset caught as adults in the 1950s are also noted. It differs morphologically from the three described species of Laotris and shows a 4.2% and 6.6% genetic distance at the CO1 barcode locus from an undescribed North American species and from the European L. striatula (Haliday, 1839), respectively.

A remarkable new family of stinging wasps from the Cretaceous of Myanmar and China (Hymenoptera, Aculeata) https://jhr.pensoft.net/article/85613/ Journal of Hymenoptera Research 94: 163-190

DOI: 10.3897/jhr.94.85613

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

Abstract: Burmese amber provides a unique window to the Cretaceous entomofauna, being the most prolific source of fossil insects for the period. Presently, about 61% of the Hymenoptera described from amber deposits in Myanmar are stinging wasps (Aculeata), including eight families known solely from Burmese amber. In the present work we describe the aculeate family †Trifionychidae fam. nov., as well as three new genera: †Prionaspidion gen. nov., including †Prionaspidion brevidens sp. nov. and †P. nanus sp. nov.; †Trifionyx gen. nov., including †Trifionyx pilosus sp. nov.; and †Trifionyximus gen. nov., including †Trifionyximus cracens sp. nov. We also reinterpret the fossil genus †Mirabythus, described based on rock impressions from the Yixian formation in China and originally attributed to Scolebythidae. †Mirabythus is moved to the new family, based mainly on the characteristic mandible; the large clypeus with a series of small denticles on the apical margin; the frons protruding over lateral portions of clypeus, directing the antennal sockets downwards below ocular level; and the presence of nine flagellomeres. Based on resemblances with fossil impressions attributed to †Bethylonymidae, we tentatively include the new family within the superfamily †Bethylonymoidea. Discovery of †Trifionychidae fam. nov. adds a novel lineage to the pool of aculeate families from the Cretaceous which did not survive to the present day.

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.

From hell’s heart I stab at thee! A determined approach towards a monophyletic Pteromalidae and reclassification of Chalcidoidea (Hymenoptera) https://jhr.pensoft.net/article/94263/ Journal of Hymenoptera Research 94: 13-88

DOI: 10.3897/jhr.94.94263

Authors: Roger Burks, Mircea-Dan Mitroiu, Lucian Fusu, John M. Heraty, Petr Janšta, Steve Heydon, Natalie Dale-Skey Papilloud, Ralph S. Peters, Ekaterina V. Tselikh, James B. Woolley, Simon van Noort, Hannes Baur, Astrid Cruaud, Christopher Darling, Michael Haas, Paul Hanson, Lars Krogmann, Jean-Yves Rasplus

Abstract: The family Pteromalidae (Hymenoptera: Chalcidoidea) is reviewed with the goal of providing nomenclatural changes and morphological diagnoses in preparation for a new molecular phylogeny and a book on world fauna that will contain keys to identification. Most subfamilies and some tribes of Pteromalidae are elevated to family level or transferred elsewhere in the superfamily. The resulting classification is a compromise, with the aim of preserving the validity and diagnosability of other, well-established families of Chalcidoidea. The following former subfamilies and tribes of Pteromalidae are elevated to family rank: Boucekiidae, Ceidae, Cerocephalidae, Chalcedectidae, Cleonymidae, Coelocybidae, Diparidae, Epichrysomallidae, Eunotidae, Herbertiidae, Hetreulophidae, Heydeniidae, Idioporidae, Lyciscidae, Macromesidae, Melanosomellidae, Moranilidae, Neodiparidae, Ooderidae, Pelecinellidae (senior synonym of Leptofoeninae), Pirenidae, Spalangiidae, and Systasidae. The following subfamilies are transferred from Pteromalidae: Chromeurytominae and Keiraninae to Megastigmidae, Elatoidinae to Neodiparidae, Nefoeninae to Pelecinellidae, and Erotolepsiinae to Spalangiidae. The subfamily Sycophaginae is transferred to Pteromalidae. The formerly incertae sedis tribe Lieparini is abolished and its single genus Liepara is transferred to Coelocybidae. The former tribe Tomocerodini is transferred to Moranilidae and elevated to subfamily status. The former synonym Tridyminae (Pirenidae) is treated as valid. The following former Pteromalidae are removed from the family and, due to phylogenetic uncertainty, placed as incertae sedis subfamilies or genera within Chalcidoidea: Austrosystasinae, Ditropinotellinae, Keryinae, Louriciinae, Micradelinae, Parasaphodinae, Rivasia, and Storeyinae. Within the remaining Pteromalidae, Miscogastrinae and Ormocerinae are confirmed as separate from Pteromalinae, the former tribe Trigonoderini is elevated to subfamily status, the former synonym Pachyneurinae is recognized as a distinct subfamily, and as the senior synonym of Austroterobiinae. The tribe Termolampini is synonymized under Pteromalini, and the tribe Uzkini is synonymized under Colotrechnini. Most former Otitesellinae, Sycoecinae, and Sycoryctinae are retained in the tribe Otitesellini, which is transferred to Pteromalinae, and all other genera of Pteromalinae are treated as Pteromalini. Eriaporidae is synonymized with Pirenidae, with Eriaporinae and Euryischiinae retained as subfamilies. Other nomenclatural acts performed here outside of Pteromalidae are as follows: Calesidae: elevation to family rank. Eulophidae: transfer of Boucekelimini and Platytetracampini to Opheliminae, and abolishment of the tribes Elasmini and Gyrolasomyiini. Baeomorphidae is recognized as the senior synonym of Rotoitidae. Khutelchalcididae is formally excluded from Chalcidoidea and placed as incertae sedis within Apocrita. Metapelmatidae and Neanastatidae are removed from Eupelmidae and treated as distinct families. Eopelma is removed from Eupelmidae and treated as an incertae sedis genus in Chalcidoidea. The following subfamilies and tribes are described as new: Cecidellinae (in Pirenidae), Enoggerinae (incertae sedis in Chalcidoidea), Erixestinae (in Pteromalidae), Eusandalinae (in Eupelmidae), Neapterolelapinae (incertae sedis in Chalcidoidea), Solenurinae (in Lyciscidae), Trisecodinae (in Systasidae), Diconocarini (in Pteromalidae: Miscogastrinae), and Trigonoderopsini (in Pteromalidae: Colotrechninae). A complete generic classification for discussed taxa is provided.

Leioproctus zephyr Prendergast (Hymenoptera, Colletidae, Leioproctus), an oligoletic new bee species with a distinctive clypeus https://jhr.pensoft.net/article/85685/ Journal of Hymenoptera Research 93: 167-188

DOI: 10.3897/jhr.93.85685

Authors: Kit S. Prendergast

Abstract: A new species Leioproctus zephyr (Hymenoptera: Colletidae) is described from both sexes. Leioproctus zephyr sp. nov. is remarkable in featuring a large longitudinal ridge on the clypeus. This diagnostic morphological feature present in both sexes, along with various other distinctive characters including the male genitalia, female hind-tibial spur, and glossa morphology, clearly distinguish this species from all other Leioproctus. Along with these unique traits, L. zephyr cannot be classified into any of the existing subgenera of Leioproctus, sharing some, but not all, of the characters of the subgenera Ceratocolletes, Charicolletes, Protomorpha and Odontocolletes. DNA barcoding with the CO1 gene confirmed the sexes belonged to the same species and it did not match any previously barcoded species. This species is restricted to native vegetation remnants in the southwest Western Australian biodiversity hotspot, and is highly specialised, foraging only on a few species in the genus Jacksonia (Fabaceae). The unusual clypeus may be an adaptation for foraging on the keeled papilionaceous flowers. The limited number of sites this species has been collected from and its oligolectic diet suggest L. zephyr should be considered to be a species of conservation concern. Further taxonomic research is required to determine the phylogenetic position of this unusual Leioproctus.

DOI: 10.3897/jhr.91.81624

Authors: Rhian Guillem, Keith Bensusan

Abstract: Three new exotic species of ants are recorded for the Macaronesian island of Madeira: Cardiocondyla obscurior Wheeler, 1929, Lepisiota capensis (Mayr, 1862) and Pheidole navigans Forel, 1901. The well-known invasive Pheidole megacephala is now rare on Madeira, possibly because of competition with P. navigans. We did not come across the Argentine ant – Linepithema humile, which was once very common in the Funchal area. Despite extensive searching, the presumed endemic Temnothorax wollastoni (Donisthorpe, 1940) remains unknown other than from the type material. Presence, abundance and extinction of invasive and exotic ants are dynamic processes and we stress the importance of continuous sampling.

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.

Integrative taxonomy based on morphometric and molecular data supports recognition of the three cryptic species within the Encyrtus sasakii complex (Hymenoptera, Encyrtidae) https://jhr.pensoft.net/article/75807/ Journal of Hymenoptera Research 90: 129-152

DOI: 10.3897/jhr.90.75807

Authors: Andrey Rudoy, Chao-Dong Zhu, Rafael R. Ferrari, Yan-Zhou Zhang

Abstract: Morphometrics has established itself as one of the most powerful tools for species delimitation, particularly for morphologically-conserved groups of insects. An interesting example is the parasitoid Encyrtus sasakii Ishii (Hymenoptera: Chalcidoidea: Encyrtidae), which was recently subdivided into three cryptic species that are seemingly well-delimited with the available DNA data but nearly indistinguishable morphologically. Here, we performed linear morphometric analyses of the antenna as well as shape analyses of the ovipositor and hypopygium (the last two are key structures associated with host location and selection) to shed further light on the taxonomic status of the E. sasakii complex. Principal component analyses were carried out to visualize the amount and direction of shape variation in the ovipositor and hypopygium. Complementarily, we constructed phylogenetic trees using a Bayesian approach based on two markers (28S and COI). We found statistically-significant differences in the relative size of the funicle and of the two proximal claval antennomeres among the three species. Our analyses also indicated that the outer plates of the ovipositor show remarkable allometric changes and that both the stylus and shield of the ovipositor are relatively well conserved among species. We nonetheless found consistent interspecific differences in the shape of the 2nd outer plate of the ovipositor and hypopygium. Also, both our COI and combined trees recovered three strongly-supported major clades, each corresponding to one of the three cryptic species. We discuss that changes in the shape of the ovipositor may have played an important role in host shift and speciation within the E. sasakii complex. Even though the recent descriptions of both E. eulecaniumiae Wang & Zhang, 2016 and E. rhodococcusiae Wang & Zhang, 2016 appear not to fully satisfy the International Code of Zoological Nomenclature, a simple resolution for the sake of taxonomic stability is proposed herein.

A new species of paper wasp from the genus Ropalidia Guérin-Méneville from South Africa (Hymenoptera, Vespidae) https://jhr.pensoft.net/article/81581/ Journal of Hymenoptera Research 90: 213-222

DOI: 10.3897/jhr.90.81581

Authors: Ozren Polašek, Terence Bellingan, Simon van Noort

Abstract: Ropalidia amabala sp. nov. is described and compared to the known African species of this genus. In addition, the nest and nesting habits are described. This species demonstrates the nesting pattern previously recorded only in Madagascar, which includes nesting directly on a tree trunk and using lichen as the nest-building source material to blend in with the surrounding lichen patches. In contrast to the Malagasy species, which clean the nesting area of lichen, this new South African species constructs the nest in a clear area of the trunk between patches of lichen. This provides excellent visual concealment of the nest and suggests that visually driven predators are the primary selective factor. The morphology for both sexes of this species disagrees with known Malagasy species, suggesting that they are separate evolutionary lineages and hence that this nesting behaviour evolved independently.

Integrated taxonomy unveils new species of Trigonalyidae (Insecta, Hymenoptera) from Yunnan, China https://jhr.pensoft.net/article/80150/ Journal of Hymenoptera Research 90: 101-128

DOI: 10.3897/jhr.90.80150

Authors: Bing-Lan Zhang, Cheng-Jin Yan, Cornelis van Achterberg, Yan-Qiong Peng, Hua-Yan Chen

Abstract: Trigonalyidae are rarely collected hyperparasitoids that attack the larvae of Ichneumonoidea, and Tachinidae associated with phytophagous sawfly or Lepidopteran larvae, or primary endoparasitoids of Vespidae larvae. Trigonalyidae mainly occur in tropical and subtropical regions, but recent studies indicate that they are found to be fairly common in mountainous regions. In this study, DNA barcoding methods based on sequences of the COI gene were used to discriminate Trigonalyidae species from Yunnan Province, which is situated in a mountaineous area of southwest China. In total, 25 COI sequences belonging to 14 morphospecies of four genera were obtained. The intraspecific pairwise distances ranged from 0 to 3.3% and the interspecific pairwise distances ranged from 5.3% to 17.3%. The delimitations of all studied species are congruent with the morphological identification results in both ABGD and bPTP methods. Based on both morphological and molecular analyses, four species from Yunnan are described as new: Jezonogonalos eburnalva Zhang & Chen, sp. nov., Lycogaster umbonata Chen & van Achterberg, sp. nov., Taeniogonalos albidorsalis Zhang & Chen, sp. nov., and T. paradoxica Zhang & Chen, sp. 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.

An unexpected new genus of panurgine bees (Hymenoptera, Andrenidae) from Europe discovered after phylogenomic analysis https://jhr.pensoft.net/article/72083/ Journal of Hymenoptera Research 89: 183-210

DOI: 10.3897/jhr.89.72083

Authors: Thomas J. Wood, Sébastien Patiny, Silas Bossert

Abstract: Establishing a higher classification of bees based on morphology alone can fail to capture evolutionary relationships when morphological characters either vary very little between distantly related groups, or conversely vary greatly between closely related species. This problem is well represented in the subfamily Panurginae, for which a recent global revision based on phylogenomic data unexpectedly revealed that two Old World species previously placed in Camptopoeum Spinola and Flavipanurgus Warncke, are in fact most closely related to each other, and together form a sister group relationship to the remaining Flavipanurgus and Panurgus Panzer combined. To rectify this situation, we here establish an expanded phylogenomic data set of Old World Panurgini and re-assess generic and subgeneric concepts for the tribe. To solve the paraphyly of Camptopoeum and Flavipanurgus, we establish the new genus Halopanurgus gen. nov. containing the species H. baldocki (Wood & Cross), comb. nov. and H. fuzetus (Patiny), comb. nov., both of which are restricted to coastal sands, saltmarshes, and inland saline lagoons in the extreme south of Portugal and south-west of Spain. Re-evaluation of four recently used subgenera in Panurgus strongly supports a simplified classification of two subgenera; Pachycephalopanurgus Patiny, stat. rev. including Micropanurgus Patiny syn. nov., and Panurgus s. str. including Euryvalvus Patiny. Pachycephalopanurgus species seem to be oligoleges of Asteroideae (Asteraceae), whereas Panurgus s. str. may be oligoleges of Cichorieae (Asteraceae). Our findings reinforce the challenges of establishing a phylogenetically sound classification of Panurginae using morphology alone and illustrate that even in well-studied regions like Europe unrecognised genera can persist in underexplored corners of the continent.

DOI: 10.3897/jhr.89.79832

Authors: Volker Mauss, Alexander V. Fateryga, Erol Yildirim, James M. Carpenter

Abstract: Celonites ivanovi sp. nov. is described as a new species from Dagestan where it has been recorded from dry habitats in a small area on the northern side of the Greater Caucasus. Celonites cagrii sp. nov. is described from Erzurum Province in east Turkey. As in other members of the C. cyprius-group, the females of both species were observed to visit flowers of Heliotropium (Boraginaceae). A morphological examination including the male genitalia of all species of the C. cyprius-group revealed that C. ivanovi sp. nov. and C. cagrii sp. nov. share the apomorphic characters of this group and are closely related to Celonites osseus Morawitz, 1888. Mean genetic distance between C. ivanovi sp. nov. and C. cagrii sp. nov. based on COI-5 sequences is 7.40%. The geographical distribution of all members of the C. cyprius-group is summarized and an illustrated key is provided for the identification of males and females of the species. A lectotype is designated for C. osseus.

Darwin wasps (Hymenoptera, Ichneumonidae) in Lower Eocene amber from the Paris basin https://jhr.pensoft.net/article/80163/ Journal of Hymenoptera Research 89: 19-45

DOI: 10.3897/jhr.89.80163

Authors: Alexandra Viertler, Seraina Klopfstein, Corentin Jouault, Tamara Spasojevic

Abstract: Despite their ecological importance, Darwin wasps (Ichneumonidae) are among the most poorly studied groups of organisms. It is therefore not surprising that their fossil record is even more poorly understood than their extant diversity. The early Eocene seems rather fossil-poor regarding Ichneumonidae in amber and only one species, Palaeometopius eocenicus Menier et al., 2004, was described so far from Oise Amber from the Paris basin. Here, two new ichneumonid genera and species, Madma oisella gen. et. sp. nov. and Pappous trichomatius gen. et. sp. nov. are described and the placement of Palaeometopius eocenicus is revised. The three fossils are well-preserved and might represent stem taxa of Tryphoninae and Phygadeuontinae. They are a highly important addition to the early Palaeogene fossil record of Ichneumonidae that otherwise mainly consists of compression fossils, which yield far less detail of the specimens’ morphology than amber pieces. Among the more than 1,000 Oise amber pieces examined, only three Ichneumonidae specimens have been found, versus about 60 Braconidae, a ratio very different from other amber deposits. Identification of additional ichneumonid specimens from this period (lowermost Eocene) is of particular importance for a better understanding of the subfamily and species compositions of this family after the K-Pg mass extinction.

The genus Orionis Shaw (Hymenoptera, Braconidae, Euphorinae) in the Old World https://jhr.pensoft.net/article/76177/ Journal of Hymenoptera Research 88: 133-145

DOI: 10.3897/jhr.88.76177

Authors: Gavin R. Broad, Julia Stigenberg

Abstract: The euphorine braconid genus Orionis Shaw, 1987 is found to be more diverse in the Old World than had previously been recognised. Orionis was regarded previously as largely Neotropical, with one Oriental species (Orionis orientalis Shimbori & Shaw, 2016) known from Thailand, but we recognise an additional three species from the Oriental and Palaearctic regions. Three species of Euphorinae are transferred to Orionis Shaw, 1987 and are new combinations: Orionis coxator (Belokobylskij, 1995), comb. nov., Orionis erratus (Chen & van Achterberg, 1997), comb. nov., and Orionis flavifacies (Belokobylskij, 2000), comb. nov. Previously known from the Far Eastern Palaearctic, O. coxator has surprisingly been found in Europe, in Belgium, England and the Netherlands. The inclusion of these species in Orionis, whereas most previous species have been described from the Neotropics, is justified by Bayesian analysis of the D2 region of 28S, Cytochrome Oxidase I barcode sequences, and morphology.

Abstract: Species of the genus Oxyscelio Kieffer are egg parasitoids of Orthoptera. The genus is relatively diverse in China, with 34 described species. Some species of the genus are extremely morphologically similar and difficult to identify, especially in males. In this study, DNA barcoding based on sequences of the COI gene was used to discriminate Oxyscelio species from southern China. In total, 49 COI sequences belonging to 22 morphospecies were obtained. The COI sequences worked well for the identification of all the studied species, with intraspecific genetic distances ranging between 0 and 4.3%, while interspecific distances ranged between 7.1% and 19%. Based on both morphological and molecular analyses, five species are described as new: O. amalocarina Mo & Chen, sp. nov., O. apheles Mo & Chen, sp. nov., O. latheticus Mo & Chen, sp. nov., O. stenos Mo & Chen, sp. nov., and O. striae Mo & Chen, sp. nov.

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.

Abstract: A morphological and molecular analysis of Gryon Haliday (Platygastroidea, Scelionidae) was conducted to provide a taxonomic and phylogenetic context for a species under evaluation as a biological control agent of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae). Our analysis revealed that Gryon is polyphyletic and that the biological control agent is not G. gonikopalense, a name that was tentatively applied to this species in 2019. We here describe this species as new, Gryon aetherium Talamas sp. nov., and resurrect the generic name Hadronotus Förster. Morphological characters that delimit our concepts of Gryon and Hadronotus are presented. Based on morphological characters and multilocus phylogenies, we determined that five presently valid scelionid genera belong within Gryon. In total, 15 species are transferred into Gryon from these genera, 215 species are transferred from Gryon to Hadronotus, and 6 species are transferred from Gryon to Dyscritobaeus Perkins. Specimens collected during field studies in California and reevaluation of specimens determined as G. myrmecophilum in Mexico reveal that G. aetherium is adventive in North America.

Stink bug egg parasitoids (Hymenoptera, Scelionidae) associated with pistachio in Iran and description of a new species: Trissolcus darreh Talamas https://jhr.pensoft.net/article/72838/ Journal of Hymenoptera Research 87: 291-308

DOI: 10.3897/jhr.87.72838

Authors: Fateme Ranjbar, M. Amin Jalali, Mahdi Ziaaddini, Zahra Gholamalizade, Elijah J. Talamas

Abstract: Surveys for egg-parasitoid wasps were conducted in Rafsanjan, Iran, on two species of Pentatomidae (Hemiptera) found in pistachio orchards, Acrosternum arabicum Wagner and Brachynema signatum Jakovlev. Five species of Scelionidae (Platygastroidea) were recovered, including one that is here described as new: Psix saccharicola (Mani), Trissolcus colemani (Crawford), T. darreh Talamas sp. nov., T. perepelovi (Kozlov), and T. semistriatus (Nees). In addition to describing a new species, we report new host associations, provide COI barcodes for four of these species, and discuss host-related intraspecific variation in T. darreh and T. perepelovi.

Molecular analysis reveals Latonius planus Kononova to be a derived species of Trissolcus Ashmead https://jhr.pensoft.net/article/63533/ Journal of Hymenoptera Research 87: 267-289

DOI: 10.3897/jhr.87.63533

Authors: Cristina Vasiliţa, Ovidiu Alin Popovici, Elijah Talamas, Norman Johnson, Lubomir Masner, Francesco Tortorici, Lucian Fusu

Abstract: The monotypic genus Latonius Kononova, 1982 (Platygastroidea, Scelionidae), was described from a single female specimen collected in southern Ukraine. It somewhat resembles Trissolcus Ashmead but has a distinctive claval formula. The only species in the genus, Latonius planus Kononova, 1982, is lacking any details regarding biology, sexual dimorphism, intraspecific variability, or distribution. Based on recently collected specimens the present study clarifies the position of Latonius within the Telenominae, provides a comprehensive description accompanied by high quality images, and compares Latonius and Trissolcus. Five molecular markers were amplified, and sequences of L. planus were analyzed using a data set for the molecular phylogeny of Telenominae (Taekul et al. 2014) and a molecular phylogeny of Trissolcus (Talamas et al. 2019). We dissected the metasoma, tarsi, antennae, and ovipositor and performed SEM imaging. The genera Latonius and Ioseppinella Mineo, O’Connor & Ashe, 2010, are treated as junior synonyms of Trissolcus and the type species of Latonius and Ioseppinella are considered to be conspecific (syn. nov.).

Review of Afrotropical sceliotracheline parasitoid wasps (Hymenoptera, Platygastridae) https://jhr.pensoft.net/article/73770/ Journal of Hymenoptera Research 87: 115-222

DOI: 10.3897/jhr.87.73770

Authors: Simon van Noort, Zachary Lahey, Elijah J. Talamas, Andrew D. Austin, Lubomir Masner, Andrew Polaszek, Norman F. Johnson

Abstract: The platygastrid subfamily Sceliotrachelinae, while represented globally by numerous biologically important taxa, is generally poorly known for the Afrotropical region. It contains a number of species of economic significance, including some that attack hemipteran pests of citrus. Here we review the taxonomy of the subfamily for the region. We revise two enigmatic, endemic South African genera, Afrisolia Masner and Huggert and Sceliotrachelus Brues, providing illustrated identification keys to the species. Afrisolia anyskop van Noort & Lahey, sp. nov., Afrisolia quagga van Noort & Lahey, sp. nov. and Afrisolia robertsoni van Noort & Lahey, sp. nov. are described for this previously monotypic genus. Sceliotrachelus was previously known only from the two male type specimens of Sceliotrachelus braunsi Brues. Two new species, Sceliotrachelus midgleyi van Noort, sp. nov. and Sceliotrachelus karooensis van Noort, sp. nov., are described from the Eastern and Western Cape, respectively. The female of S. braunsi is described for the first time and additional distribution records for the species are documented. The putatively basal species, S. karooensis, exhibits less derived morphology than the highly apomorphic S. braunsi, necessitating reassessment of the limits of the genus. The exceptional morphology exhibited by species of Sceliotrachelus is hypothesized to be an adaptation to living in leaf-litter. We also revise the Old World species of Parabaeus Kieffer, describing a remarkable new species, Parabaeus nasutus van Noort, sp. nov., and provide an illustrated and updated key to the species. Fidiobia Ashmead is currently represented in Africa by seven described species to which we add Fidiobia celeritas van Noort & Lahey, sp. nov., a charismatic new species from South Africa. The distribution of the genus Isolia is expanded to include new country records for I. hispanica Buhl (Kenya) and an undescribed species from Madagascar. To facilitate the ongoing exploration and documentation of the African platygastrid fauna, an identification key to Afrotropical sceliotracheline genera and high resolution images of exemplar species for the remaining genera are provided. An overview of known species richness and biology is also included. All images presented here as well as additional images and interactive online Lucid identification keys are available on WaspWeb at http://www.waspweb.org.

Authors: Sangjin Kim, Željko Tomanović, Yeonghyeok Yu, JuHyeong Sohn, Yunjong Han, Gyeonghyeon Lee, Hyojoong Kim

Abstract: Several species of the genus Aphidius are well known as commercial biocontrol agents of pest aphids, and more than 130 species of the genus have been recorded worldwide. To date, only 15 Aphidius species have been recorded in South Korea. Using the DNA barcode region (ca. 658 bp) of mitochondrial cytochrome c oxidase subunit I (COI), we amplified sequences of 15 Aphidius Korean species, aligned them in combination with 23 reference species retrieved from GenBank for comparison and identification, and then reconstructed a barcode phylogeny by the neighbour-joining method. As a result, three Aphidius species were found to be new to Science. Descriptions and illustrations of the three species new to Science – Aphidius longicarpus sp. nov., A. longistigmus sp. nov., and A. asiaticus sp. nov. – are provided, together with their phylogenetic position within the genus Aphidius. In addition, a redescription of A. areolatus, a parasitoid of maple aphids (Peryphillus spp.), is also given.

The Waterston’s evaporatorium of Ceraphronidae (Ceraphronoidea, Hymenoptera): A morphological barcode to a cryptic taxon https://jhr.pensoft.net/article/67165/ Journal of Hymenoptera Research 85: 29-56

DOI: 10.3897/jhr.85.67165

Authors: Jonah M. Ulmer, István Mikó, Andrew R. Deans, Lars Krogmann

Abstract: The Waterston’s evaporatorium (=Waterston’s organ), a cuticular modification surrounding the opening of an exocrine gland located on metasomal tergite 6, is characterized and examined for taxonomic significance within the parasitoid wasp family Ceraphronidae. Modification of the abdominal musculature and the dorsal vessel are also broadly discussed for the superfamily Ceraphronoidea, with a novel abdominal pulsatory organ for Apocrita being discovered and described for the first time. Cuticular modification of T6, due to the presence of the Waterston’s evaporatorium, provides a character complex that allows for genus- and species-level delimitation in Ceraphronidae. The matching of males and females of a species using morphology, a long standing challenge for the group, is also resolved with this new character set. Phylogenetic analysis including 19 Waterston’s evaporatorium related characters provides support for current generic groupings within the Ceraphronidae and elaborates on previously suggested synapomorphies. Potential function of the Waterston’s organ and its effects on the dorsal vessel are discussed.

Revision of the West Palaearctic Euura bergmanni and oligospila groups (Hymenoptera, Tenthredinidae) https://jhr.pensoft.net/article/68637/ Journal of Hymenoptera Research 84: 187-269

DOI: 10.3897/jhr.84.68637

Authors: Marko Prous, Andrew Liston, Marko Mutanen

Abstract: Eight Western Palaearctic Euura species are here assigned to the bergmanni group (bergmanni, brevivalvis, dispar, glutinosae, leptocephalus, respondens, sylvestris, and viridis) and two species to the oligospila group (frenalis and oligospila). Euura pallens (Konow, 1903) (bergmanni group) is removed from the list of West Palaearctic taxa. Euura pyramidalis (Hellén, 1948) is treated as incertae sedis within the bergmanni group. Definitions of the bergmanni and oligospila groups are primarily based on genetic sequence data (mitochondrial COI and nuclear NaK and POL2). We report likely occurrence of heteroplasmy and amplification of NUMTs among some of the treated species, complicating the use of DNA barcoding in species discrimination. Based on morphological and genetic evidence, we establish that the correct name for the invasive willow sawfly in the southern hemisphere (South America, southern Africa, Australia, New Zealand), known there only in the female sex, is Euura respondens (Förster, 1854). The species is probably native to the Palaearctic (or even Holarctic) where males are common: possibly as common as females (examined from Europe and Central Asia). The name Euura oligospila (Förster, 1854) has been incorrectly used for the species in the southern hemisphere. The examination of type material and reliable association of males and females based on genetics revealed that females of E. oligospila are morphologically extremely similar to E. respondens (and to some other E. bergmanni group species), but male penis valves and genetics enable reliable separation of these species. Morphological separation of females of E. oligospila and E. respondens is possible, but challenging. Identification keys for males and females of the bergmanni and oligospila groups are provided. The following 15 new synonymies are proposed: Nematus validicornis Förster, 1854, syn. nov. with Euura bergmanni (Dahlbom, 1835); Pteronidea woollatti Lindqvist, 1971, syn. nov. and Nematus turgaiensis Safjanov, 1977, syn. nov. with Euura brevivalvis (Thomson, 1871); Pteronidea pseudodispar Lindqvist, 1969, syn. nov. with Euura dispar (Zaddach, 1876); Nematus (Pteronidea) fastosus var. ponojense Hellén, 1948, syn. nov. and N. (P.) fastosus var. punctiscuta Hellén, 1948, syn. nov. with Euura frenalis (Thomson, 1888); Nematus declaratus Muche, 1974, syn. nov. and N. desantisi D.R. Smith, 1983, syn. nov. with Euura respondens (Förster, 1854); Pteronidea straminea Lindqvist, 1958, syn. nov., P. angustiserra Lindqvist, 1969, syn. nov., and P. disparoides Lindqvist, 1969, syn. nov. with Euura sylvestris (Cameron, 1884); Pteronidea breviseta Lindqvist, 1946, syn. nov., P. breviseta Lindqvist, 1949, syn. nov., P. abscondita Lindqvist, 1949, syn. nov., and P. lauroi Lindqvist, 1960, syn. nov. with Euura viridis (Stephens, 1835). Lectotypes are designated for 18 nominal taxa: Amauronematus longicornis Konow, 1897; A. spurcus Konow, 1904; Nematus bergmanni Dahlbom, 1835; N. brevivalvis Thomson, 1871; N. curtispina Thomson, 1871; N.

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.

The genus Ismarus Haliday (Hymenoptera, Ismaridae) from China https://jhr.pensoft.net/article/62148/ Journal of Hymenoptera Research 82: 139-160

DOI: 10.3897/jhr.82.62148

Authors: Xiao Zhang, Hua-yan Chen, Jing-xian Liu, Shi-xiao Luo

Abstract: The genus Ismarus Haliday from China is revised. Six species are recognized, of which two species are described as new: Ismarus areolatus Chen, sp. nov., and Ismarus paradorsiger Chen, sp. nov. By examining the pits along the anterolateral margin of mesoscutum and comparing them with the typical notauli in Diapriidae, we conclude that the so-called reduced notauli in Ismarus are actually foveae of the mesoscutual suprahumeral sulcus. An updated key to the Chinese species of the genus is provided.

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).
