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.

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.

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.

A semantically enriched taxonomic revision of Gryonoides Dodd, 1920 (Hymenoptera, Scelionidae), with a review of the hosts of Teleasinae https://jhr.pensoft.net/article/72931/ Journal of Hymenoptera Research 87: 523-573

DOI: 10.3897/jhr.87.72931

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.

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.

The first gynandromorph of the Neotropical bee Megalopta amoena (Spinola, 1853) (Halictidae) with notes on its circadian rhythm https://jhr.pensoft.net/article/47828/ Journal of Hymenoptera Research 75: 97-108

DOI: 10.3897/jhr.75.47828

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.

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.

Beta diversity of four braconid subfamilies (Braconidae, Agathidinae, Braconinae, Doryctinae and Macrocentrinae) of the Ria Lagartos Biosphere reserve in Yucatan, Mexico, with some considerations on biological habits https://jhr.pensoft.net/article/28982/ Journal of Hymenoptera Research 67: 63-83

DOI: 10.3897/jhr.67.28982

Authors: Roger Cauich-Kumul, Hugo Delfín-González, Abdiel Martín-Park, Pablo Manrique-Saide, Víctor López-Martínez

Abstract: The species diversity composition and phenological behaviour of four braconid subfamilies (Hymenoptera: Braconidae: Agathidinae, Braconinae, Doryctinae and Macrocentrinae) were monitored in three vegetation communities (dune vegetation, tropical deciduous forest and savannah) of the Ria Lagartos Biosphere Reserve (RLBR) in Yucatan, Mexico. Braconid wasps were collected with Malaise traps every 15 days over one year (June 2008 to June 2009). A total of 2,476 specimens were inventoried comprising 233 species and 63 genera. The composition of braconids and their lifestyles differed among the three vegetation communities studied. Doryctinae was the most diverse and abundant subfamily in RLBR (40 genera, 145 species, 990 specimens) and the tropical deciduous forest recorded the maximum abundance and diversity (H’= 4.1; alpha value= 1.059), with 61 exclusive species. Phenological sequence indicates an influence of the rainy season in braconid diversity, but its effects differed among braconid subfamilies and among the vegetation communities. Finally, the importance of the RBRL as a conservation site for this hymenopterous wasp is discussed.

On the identity of the adventive species of Eufriesea Cockerell in the USA: systematics and potential distribution of the coerulescens species group (Hymenoptera, Apidae) https://jhr.pensoft.net/article/12209/ Journal of Hymenoptera Research 55: 55-102

DOI: 10.3897/jhr.55.12209

Authors: Victor H. Gonzalez, Terry Griswold, Marianna Simões

Abstract: In the summer of 2010, two male specimens of the neotropical orchid bee genus Eufriesea Cockerell were collected in the Guadalupe Mountains of western Texas and southeastern New Mexico, USA. We tentatively identified them as E. coerulescens (Lepeletier de Saint Fargeau) because of the uncertainty surrounding the limits of this taxon and hypothesized that they were members of a persistent bee population, rather than long-distance transient vagrants. The goals of this paper are to clarify the identity of these specimens, assess the species limits of E. coerulescens, and to evaluate suitability of habitats in the USA for this adventive species. Herein, we revise the species in the coerulescens group using morphological features of both sexes and confirm that the specimens of Eufriesea from the USA are E. coerulescens. We recognize the following six species in the coerulescens group: E. coerulescens, E. micheneri Ayala & Engel, E. simillima (Moure & Michener), which is reinstated from synonym with E. coerulescens, and three new species from Mexico (E. barthelli Gonzalez & Griswold, sp. n., E. engeli Gonzalez & Griswold, sp. n., and E. oliveri Gonzalez & Griswold, sp. n.). To facilitate the identification of these taxa, we present a fully illustrated account of the species, comparative diagnoses, descriptions, and an updated key to all Mexican species of Eufriesea. Our analyses using species distribution modelling show an absence of suitable habitat for E. coerulescens in western Texas and southeastern New Mexico, thus favoring the long-distance dispersal hypothesis. The analyses also suggest high suitability of habitats across the Caribbean and some areas in Florida, as well as in other regions in Mexico and Central America. We discuss the implications of these results and compare them with the predicted distribution available for the other two known adventive orchid bee species in the USA.

Revision of the genus Promicrogaster (Hymenoptera, Braconidae, Microgastrinae) from Area de Conservación Guanacaste, Costa Rica, with a key to all species previously described from Mesoamerica https://jhr.pensoft.net/article/8220/ Journal of Hymenoptera Research 50: 25-79

DOI: 10.3897/JHR.50.8220

Authors: Jose Fernandez-Triana, Caroline Boudreault, Tanya Dapkey, M. Alex Smith, Josephine Rodriguez, Winnie Hallwachs, Daniel H. Janzen

Abstract: The genus Promicrogaster (Hymenoptera, Braconidae, Microgastrinae) from Area de Conservación Guanacaste (ACG), Costa Rica, is revised. A key is provided to all new species as well as those previously described from Mesoamerica. A total of 21 species, all authored by Fernandez-Triana & Boudreault, are described as species nova: alexmartinezi, andreyvallejosi, brandondinartei, daniellopezi, daretrizoi, eddycastroi, eimyobandoae, fabiancastroi, fabriciocambroneroi, hillaryvillafuerteae, kevinmartinezi, kiralycastilloae, leilycastilloae, liagrantae, luismendezi, monteverdensis, naomiduarteae, pablouzagai, ronycastilloi, sebastiancambroneroi, tracyvindasae. A species previously described from India is considered as incertae sedis. Promicrogaster is considered to be restricted to the New World, with the vast majority of the species found in the Neotropics and a few extending north to the Nearctic. Almost 60% of the known species in ACG are found in cloud forests at over 1,000 m altitude. All of the verified and authenticated host records for Promicrogaster are from caterpillars living more deeply inside plant tissue than simply in rolled leaf structures – although no host data from ACG is available.

Doryctobracon areolatus (Hymenoptera, Braconidae) a parasitoid of early developmental stages of Anastrepha obliqua (Diptera, Tephritidae) https://jhr.pensoft.net/article/5586/ Journal of Hymenoptera Research 46: 91-105

DOI: 10.3897/JHR.46.5586

Authors: Félix D. Murillo, Héctor Cabrera-Mireles, Juan F. Barrera, Pablo Liedo, Pablo Montoya

Abstract: Natural parasitism of Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae) on various development stages of Anastrepha obliqua (Macquart) (Diptera: Tephritidae) attacking Spondias mombin L. fruits was studied under field conditions. We collected 120 fruits of S. mombin from which we got 495 A. obliqua larvae of different instars. A total of 88% of these larvae were parasitized. Within the parasitized cohort, the first-instar of D. areolatus was frequently detected in all 3 larval stages (L1 = 94.3%, L2 = 98.1%, and L3 = 100%), and the rest (i.e., L1 = 5.7%, L2 = 1.8%) corresponded to the presence of eggs. In fruits with controlled infestation and cage-induced parasitism under field conditions, D. areolatus oviposited in mature eggs and recently hatched larvae of A. obliqua with comparable frequencies. Seven preimaginal stages of D. areolatus were observed during their development, which was completed in 27 days. It is concluded that D. areolatus has the capacity to oviposit in embryo eggs and neonate larvae of A. obliqua and that its first-instar larvae (with three distinct sizes) are capable of synchronizing their development with the development of the host larvae. This finding represents the first report of a native parasitoid attacking eggs or neonate larvae of a tephritid in the Neotropics. The implications of this finding are discussed within the context of the competitive interactions of this species with other parasitoid species under sympatric conditions, as well as the relevance for developing laboratory rearing methods for biological control purposes.

Revision of the neotropical genus Sendaphne Nixon (Hymenoptera, Braconidae, Microgastrinae) https://jhr.pensoft.net/article/4387/ Journal of Hymenoptera Research 41: 1-29

DOI: 10.3897/JHR.41.8586

Authors: Jose L. Fernandez-Triana, James B. Whitfield, M. Alex Smith, Winnie Hallwachs, Daniel H. Janzen

Abstract: The Neotropical genus of parasitoid wasps Sendaphne (Hymenoptera, Braconidae, Microgastrinae) is revised and the following six new species are described, all authored by Fernández-Triana and Whitfield: anitae, bennetti, broadi, dianariaspennae, penteadodiasae, and rogerblancoi. The greatest species richness is found in northern South America, but the genus extends north to 23° N in Mexico. Most species have been collected in rainforest below altitudes of 900 m, with only a few species found in cloud forests up to 1900 m. Nothing is known of the host caterpillars for these parasitoid wasps.

Parasitoid wasps from three Jamaican localities: A pilot study https://jhr.pensoft.net/article/1656/ Journal of Hymenoptera Research 37: 127-135

DOI: 10.3897/jhr.37.7081

Authors: Fadia Ceccarelli, Dwight Robinson, Hans Clebsch, Alejandro Zaldivar-Riveron

Abstract: Parasitoid wasps are an extremely speciose, ecologically and economically crucial group of insects. Despite this, they have received disproportionally little attention from scientists, in particular in certain areas of the world. One such area is the Caribbean, where studies are scarce despite the importance of parasitoid wasps, and the uniqueness and diversity of the Caribbean islands. To verify whether an adequate diversity of parasitoid wasps at family level can be found to warrant future studies, this study carries out preliminary sampling in three localities in Jamaica. A total of 1522 individual parasitoid wasps, belonging to at least 16 different families collected during 16 events provide preliminary evidence there is in fact a high diversity of parasitoid wasps in Jamaica, and that future studies there, as in the rest of the Caribbean are definitely worthwhile.

Review of the Neotropical genus Prasmodon (Hymenoptera, Braconidae, Microgastrinae), with emphasis on species from Area de Conservación Guanacaste, northwestern Costa Rica https://jhr.pensoft.net/article/1661/ Journal of Hymenoptera Research 37: 1-52

DOI: 10.3897/jhr.37.6748

Authors: Jose Fernandez-Triana, James Whitfield, M. Alex Smith, Yves Braet, Winnie Hallwachs, Daniel Janzen

Abstract: The Microgastrinae genus Prasmodon is revised and the following 16 new species are described: erenadupontae and verhoogdenokus (authored by Braet and Fernández-Triana), and almasolisae, aureus, bobpoolei, bobrobbinsi, dondavisi, johnbrowni, masoni, mikepoguei, nixoni, paulgoldsteini, scottmilleri, silvatlanticus, subfuscus, and tijucaensis (authored by Fernández-Triana and Whitfield). The greatest species richness is found in the Amazon basin, but the genus extends throughout the rain forests of Central and South America. Leaf-rolling and webbing caterpillars of Crambidae and Elachistidae are the only known hosts for these parasitoids.

Food plants and life histories of sawflies of the families Argidae and Tenthredinidae (Hymenoptera) in Costa Rica, a supplement https://jhr.pensoft.net/article/1650/ Journal of Hymenoptera Research 35: 17-31

DOI: 10.3897/jhr.35.5496

Authors: David Smith, Daniel Janzen, Winnie Hallwachs

Abstract: Food plants and information on life history are presented for six species of Argidae and four species of Tenthredinidae in Costa Rica. The Argidae include cocoons of Atomacera josefernandezi Smith, sp. n., found on Hampea appendiculata (Donn. Sm.) Standl. (Malvaceae) and likely feeding on its leaves before pupation, and larvae of Eriglenum tristum Smith feeding on Machaerium seemanii Benth. Ex Seem. (Fabaceae), Ptenos leucopodus (Cameron) feeding on Inga oerstediana Benth. and I. vera Willd. (Fabaceae), Ptilia peleterii (Gray) feeding on Cnestidium rufescens (Connaraceae), and Scobina lepida (Klug) and S. notaticollis (Konow) feeding on Sida rhombifolia L. (Malvaceae). The Tenthredinidae include larvae of Dochmioglene crassa (Cameron) feeding on the fern Lomariopsis vestita E. Fourn. (Lomariopsidaceeae), Dochmiogleme Smith03 feeding on Blechnum occidentale L. (Blechnaceae), Waldheimia laeta (Cameron) feeding on Cissus alata Jacq. (Vitaceae), and Waldheimia lucianocapellii Smith, sp. n., feeding on Davilla nitida (Vahl) Kubitzki (Dilleniaceae). Waldheimia lucianocapellii is described from specimens from both Panama and Costa Rica. Selandria crassa Cameron, 1883 is a comb. n. in Dochmioglene.

A new genus and species of fairyfly, Tinkerbella nana (Hymenoptera, Mymaridae), with comments on its sister genus Kikiki, and discussion on small size limits in arthropods https://jhr.pensoft.net/article/1635/ Journal of Hymenoptera Research 32: 17-44

DOI: 10.3897/jhr.32.4663

Authors: John Huber, John Noyes

Abstract: A new genus and species of fairyfly, Tinkerbella nana (Hymenoptera: Mymaridae) gen. n. and sp. n., is described from Costa Rica. It is compared with the related genus Kikiki Huber and Beardsley from the Hawaiian Islands, Costa Rica and Trinidad. A specimen of Kikiki huna Huber measured 158 µm long, thus holding the record for the smallest winged insect. The smallest size possible, as measured by body length, for flying insects and wingless arthropods is discussed.

Hyperparasitoid wasps (Hymenoptera, Trigonalidae) reared from dry forest and rain forest caterpillars of Area de Conservación Guanacaste, Costa Rica https://jhr.pensoft.net/article/1609/ Journal of Hymenoptera Research 29: 119-144

DOI: 10.3897/jhr.29.3233

Authors: David Smith, Daniel Janzen, Winnie Hallwachs, M. Alex Smith

Abstract: Five species of Trigonalidae, hyperparasitoids of Ichneumonidae (Hymenoptera) and Tachinidae (Diptera) that parasitize caterpillars (Lepidoptera), have been reared during the ongoing caterpillar inventory of Area de Conservación Guanacaste (ACG), Guanacaste Province, northwestern Costa Rica: Lycogaster apicipennis (Cameron), Taeniogonalos woodorum Smith, sp. n., Taeniogonalos fasciatipennis (Cameron), Trigonalys championi Cameron, and Trigonalys maculifrons Sharp. Morphological and DNA barcoding data support species separation of these generalist hyperparasitoids. Taeniogonalos gundlachii (Cresson) is not a widespread, color-variable species as previously treated and is probably confined to eastern North America. The species previously considered as T. gundlachii in Costa Rica is regarded as Taeniogonalos fasciatipennis, a species found only in ACG dry forest. Taeniogonalos woodorum is a similar species but found only in the ACG rain forest. Habitat and host records are given for these five species of trigonalids.

Two new species of Pambolus (Hymenoptera, Braconidae) from Jamaica https://jhr.pensoft.net/article/1581/ Journal of Hymenoptera Research 24: 85-93

DOI: 10.3897/jhr.24.2300

Authors: Juan Martínez, Fadia Ceccarelli, Alejandro Zaldivar-Riveron

Abstract: Pambolus albospina sp. n. and Pambolus rastafari sp. n. are described from Jamaica. Pambolus rastafari can be distinguished from all other Neotropical species of the genus by its antennal color pattern and the smooth sculpture of the head and mesoscutum. Pambolus albospina is morphologically close to P. hemitaeniatus van Achterberg, from which it can be distinguished by the number of white antennal segments and the sculpture on the first metasomal tergite. These two new species constitute the first records of the genus for the Caribbean Islands.

Characteristics of the cocoon and natural history of the gregarious Meteorus restionis sp. n. (Hymenoptera, Braconidae, Meteorinae) from Costa Rica https://jhr.pensoft.net/article/1560/ Journal of Hymenoptera Research 20: 9-21

DOI: 10.3897/jhr.29.867

Authors: Gilbert Barrantes, Emilia Triana, Scot Shaw, Guinevere Jones

Abstract: A new species of a gregarious Meteorus wasp (Braconidae) constructs an unusual cocoon mass. Meteorus restionis sp. n. is described and distinguished from similar species. Cocoons of M. restionis are dark-brown, ovoid, and they are attached perpendicularly by their posterior end along a long, suspended cable. The cable is formed by intertwined, independent threads which are glued together at irregular intervals along its length, suggesting a certain degree of cooperation or at least tolerance among larvae during the construction of the cable. Intertwining and gluing the individual threads in a single cable presumably gives it a greater resistance against wind and other environmental stress. Prior to emergence the wasp cuts a neat, circular cap at the anterior end of its cocoon, and the cap remains attached by some threads to the rest of the cocoon.
