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.

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

DOI: 10.3897/jhr.96.100862

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

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

First record of the parasitoid subfamily Doryctinae (Hymenoptera, Braconidae) in Rovno amber: description of a new genus and species with stigma-like enlargement on the hind wing of the male https://jhr.pensoft.net/article/96784/ Journal of Hymenoptera Research 95: 59-72

DOI: 10.3897/jhr.95.96784

Authors: Sergey A. Belokobylskij, Serguei A. Simutnik, Dmitry V. Vasilenko, Evgeny E. Perkovsky

Abstract: A new genus and species of the braconid parasitoid subfamily Doryctinae, Eocenhecabolus kotenkoi gen. et sp. nov., from the late Eocene Rovno amber are described and illustrated. Eocenhecabolus gen. nov. is the first unambiguously extinct Doryctinae genus. This genus is described from the male and characterised by the followings features: in the fore wing by the postfurcal position of the recurrent vein (m-cu) relatively to the first radiomedial vein (2-SR), and a distally open brachial (second subdiscal) cell; in the hind wing by the presence of the elementary stigma-like enlargement on the distal half of the costal (1-SC+R) vein. The different types of stigma-like enlargements found in the hind wings of males in the subfamily Doryctinae are discussed.

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.

Electronoyesella antiqua Simutnik, gen. et sp. nov. (Chalcidoidea, Encyrtidae) from Rovno amber https://jhr.pensoft.net/article/94773/ Journal of Hymenoptera Research 94: 105-120

DOI: 10.3897/jhr.94.94773

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Dmitry V. Vasilenko

Abstract: Electronoyesella antiqua Simutnik, gen. et sp. nov., is described and illustrated based on a female specimen from late Eocene Rovno amber. Like most previously described Eocene Encyrtidae, the new taxon differs from the majority of extant ones in a number of features. Sclerotised metasomal structures, similar to the paratergites of extant Tetracneminae, are seen here for the first time in fossils. The new genus is characterized also by the frontovertex with four vertical rows of piliferous punctures and the face also with intricate sculpture; notauli are present as small but distinct depressions, only anteriorly; the apex of metatibia with a peg originating from a round, deep pit; and the unusual setation of the hind wing.

A new species of Bocchus from upper Eocene Rovno amber (Hymenoptera, Dryinidae) https://jhr.pensoft.net/article/87084/ Journal of Hymenoptera Research 92: 257-272

DOI: 10.3897/jhr.92.87084

Authors: Massimo Olmi, Benjamin Eggs, Leonardo Capradossi, Thomas van de Kamp, Evgeny E. Perkovsky, Adalgisa Guglielmino, Dmitry V. Vasilenko

Abstract: A new fossil species of Dryinidae (Hymenoptera, Chrysidoidea) from upper Eocene Rovno amber (Ukraine) is described: Bocchus rex sp. nov. It is compared with two other species of Bocchus known from European amber: B. primaevus Martins & Melo from Baltic amber and B. schmalhauseni Perkovsky, Olmi, Vasilenko, Capradossi & Guglielmino from Rovno amber. A new key to the Cretaceous and Paleogene species of Bocchus is presented. The Dryininae are the most common representatives in all the amber dryinid faunas since the mid-Cretaceous. The Rovno amber fauna is an exception; possible explanations for the abundance of Bocchus species within this amber are presented.

Protaphycus shuvalikovi Simutnik gen. et sp. nov. (Chalcidoidea, Encyrtidae, Encyrtinae) from Rovno amber https://jhr.pensoft.net/article/81957/ Journal of Hymenoptera Research 91: 1-9

DOI: 10.3897/jhr.91.81957

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Dmitry V. Vasilenko

Abstract: Protaphycus shuvalikovi Simutnik gen. et sp. nov., the smallest fossil Encyrtidae, is described and illustrated based on female specimen from late Eocene Rovno amber. Like most previously described Eocene Encyrtidae, the new taxon differs from the majority of extant encyrtids by the subapical position of the cerci, the relatively long marginal vein of the forewing, a distinctly swollen but not triangular parastigma, and a seta marking the apex of the postmarginal vein is not any longer than others on this vein. The new genus is characterized by the presence of a filum spinosum and the hypopygium reaching way past the apex of syntergum. This combination of the character states is known only in a few representatives of extant Encyrtinae. The new genus, probably, most closely related to the extant genus Aphycus Mayr, 1876.

Two new genera of Encyrtidae (Hymenoptera, Chalcidoidea) with reduced ovipositor sheaths https://jhr.pensoft.net/article/79180/ Journal of Hymenoptera Research 89: 47-60

DOI: 10.3897/jhr.89.79180

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Mykola R. Khomych, Dmitry V. Vasilenko

Abstract: Archaeocercoides puchkovi Simutnik, gen. et sp.nov., and Rovnopositor voblenkoi Simutnik, gen. et sp.nov., are described and illustrated based on female specimens from late Eocene Rovno amber. Like most previously described Eocene Encyrtidae, the new taxa differ from the majority of extant encyrtids by the apical or nearly apical position of the cerci, the short radicle, and the long marginal vein of the forewing. Both new genera are characterized by a strongly reduced ovipositor sheaths but long and upwardly bent ovipositor stylets (in the “ovipositing position”), a stigmal vein with a long uncus, and the absence of a filum spinosum. The new genera differ from each other in the width of frontovertex, the location of the cerci, and the lengths of funicular segments and marginal vein. A. puchkovi was fossilized near a Coccoidea crawler.

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.

DOI: 10.3897/jhr.88.75941

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Mykola R. Khomych, Dmitry V. Vasilenko

Abstract: Sulia glaesaria Simutnik, 2015 (Chalcidoidea, Encyrtidae), originally described from late Eocene Danish amber, is reported in coeval Rovno amber. A revised diagnosis of this genus is provided based on the new specimen and high-resolution photomicrographs of the holotype. Some character states, such as a short radicle, clypeus with long lateral margins, the presence of a strigil and basitarsal comb, spur vein of the hind wing, costal cell of hind wing along entire marginal vein with single line of long setae, and almost vertical syntergum with abruptly reflexed extension apically are reported in this species for the first time.

A new genus of anaxyelid wood wasps from the mid-Cretaceous and the phylogeny of Anaxyelidae (Hymenoptera) https://jhr.pensoft.net/article/73161/ Journal of Hymenoptera Research 86: 151-169

DOI: 10.3897/jhr.86.73161

Authors: Jia Gao, Michael S. Engel, Chungkun Shih, Dong Ren, Taiping Gao

Abstract: Two new species of wood wasps (Anaxyelidae), Orthosyntexis elegans gen. et sp. nov. and Orthosyntexis thanti sp. nov., are described from mid-Cretaceous Kachin amber. Orthosyntexis gen. nov. exhibits characters and character combinations unique to the family, such as the combination of two mesotibial spurs, a length ratio of forewing 1Rs to 1M<1, a length to width ratio of forewing cell 1mcu ≥ 2, and the presence of 2M+Cu in the hind wing. The new species and morphological characters allow for an exploration of anaxyelid phylogeny. The phylogenetic results indicate that Anaxyelidae are monophyletic and it is suggested to classify the genera in two subfamilies, Syntexinae and Anaxyelinae, the latter including Kempendajinae and Dolichostigmatinae.

A new genus and species of Pristocerinae (Hymenoptera, Bethylidae) from upper Eocene Baltic amber with a review of conspecific association from insect fossils https://jhr.pensoft.net/article/68658/ Journal of Hymenoptera Research 85: 119-133

DOI: 10.3897/jhr.85.68658

Authors: Carly Melissa Tribull, Madeline V. Pankowski, Wesley Dondoni Colombo

Abstract: A new extinct genus and species of Pristocerinae, †Archeonesia eocena Tribull, Pankowski & Colombo, gen. et. sp. nov., are described from upper Eocene Baltic amber from the Yantarny amber mine in the Kaliningrad region, Russia. Descriptions, remarks, illustrations, and comparisons to all extinct and extant Pristocerinae are provided. †Archeonesia is described as a new genus because neither the male nor the female can be placed in any previously described genera, although the female is most similar to Acrenesia and the male is most similar to Cleistepyris. Rare for Bethylidae, and Hymenoptera in general, this fossil contains both a male and female specimen that we are describing as conspecifics. A brief review from the paleoentomological literature is provided to describe how insect fossils containing evidence of reproductive behavior have been used to associate conspecifics in extinct species.

Sakhalinencyrtus leleji Simutnik gen. et sp. nov. of earliest Encyrtidae (Hymenoptera, Chalcidoidea) from Sakhalinian amber https://jhr.pensoft.net/article/66367/ Journal of Hymenoptera Research 84: 361-372

DOI: 10.3897/jhr.84.66367

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Dmitry V. Vasilenko

Abstract: Another earliest representative of the family Encyrtidae, Sakhalinencyrtus leleji Simutnik gen. et sp. nov., is described and illustrated based on a male specimen from the middle Eocene Sakhalinian amber. Similarly to other Encyrtidae from Sakhalinian amber, the new fossil fundamentally differs from encyrtids from late Eocene European ambers as well as from modern ones. Moreover, it probably belongs to a stem group of the family. The new genus is characterized by extremely apical position of cerci, long veins of the forewing with expanded parastigma, stigmal vein with long uncus, and absence of filum spinosum. The forewing venation of the new genus is very similar to that of Sugonjaevia Simutnik, 2015, but these genera differ by the structure of Mt8, hypopygium, genitalia, and clava.

Authors: Alexander G. Radchenko, Maxim Yu. Proshchalykin

Abstract: A new fossil myrmicine ant genus and species Lelejus venustus gen. et sp. nov., are described from late Eocene Rovno amber (Priabonian, 33.9–37.8 Ma). This genus differs from all extant and extinct Myrmicinae genera known from the late Eocene European ambers in the combination of morphological features, in particular: 13-segmented antennae with a very short scape and filiform funiculus; 3-segmented maxillary and 2-segmented labial palps; well-developed mandibles with dentate masticatory margin; scutum with broad notauli; forewings with closed cells 1+2r, 3r and mcu, the cell 3r of approximately the same length as cell 1+2r; free vein M branches off from RS approximately at the midlength between the junction of cross-vein 2r-rs with RS and vein m-cu; the cross-vein cu-a is located far from the base of wing, so the branch 1M+Cu is much longer than 2M+Cu. The taxonomic position of the described genus is discussed.

Formica species (Hymenoptera, Formicidae, Formicinae) in late Eocene Rovno amber https://jhr.pensoft.net/article/64599/ Journal of Hymenoptera Research 82: 237-251

DOI: 10.3897/jhr.82.64599

Authors: Alexander G. Radchenko, Evgeny E. Perkovsky, Dmitry V. Vasilenko

Abstract: A new species, Formica ribbeckei Radchenko & Perkovsky, sp. nov., is described based on four workers from late Eocene Rovno amber (Ukraine). It most resembles F. flori Mayr, 1868 but differs from the latter mainly by the 5-segmented maxillary palps with the preapical segment subequal in length to the apical one, and by the shorter first funicular segment. Fossil F. luteola Presl, 1822, F. trigona Presl, 1822, F. macrognatha Presl, 1822 and F. quadrata Holl, 1829 are considered incertae sedis in Formicidae. Thus, ten valid Formica Linnaeus, 1758 species (including F. ribbeckei) are known now from late Eocene European ambers. The diversity of Formica in the early and middle Eocene deposits of Eurasia and North America is considered. It is assumed that the genus Formica most likely arose in the early Eocene.

Abstract: Two new species of Hybristodryinus Engel, 2005, are described from mid-Cretaceous amber of northern Myanmar: H. castaneus sp. nov. (based on one male) and H. zaifui sp. nov. (based on one female). Keys to the females and males of Hybristodryinus species are modified to include the two new taxa. A syninclusion, a nymph of Cixitettiginae (Perforissidae), present in the same amber piece containing H. zaifui, is studied. This syninclusion, together with the presence of Antennal Dorsal Organs (ADOs) in Hybristodryinus, suggests that Perforissidae are possible hosts of Hybristodryinus.

Abstract: The large and distinctive chalcidoid wasp Leptoomus janzeni Gibson, 2008, originally described from late Eocene Baltic amber, is newly recorded from coeval Rovno amber (Ukraine) based on a single well-preserved female specimen. Only 66 species of Rovno hymenopterans (49%) are also known from Baltic amber. High resolution photomicrographs and measurements of the specimen are given. Some character states of the new specimen, such as a green metallic coloration, a bare and flat prepectus, location and number of multiporous plate sensillae on the flagellum, sclerotized spur vein of the hind wing, and two metatibial spur are reported in this species for the first time.

Revision of the fossil species of Thaumatodryinus Perkins from Dominican amber, with a new combination and description of a new species (Hymenoptera, Dryinidae) https://jhr.pensoft.net/article/57686/ Journal of Hymenoptera Research 79: 77-88

DOI: 10.3897/jhr.79.57686

Authors: André L. Martins, Gabriel A. R. Melo

Abstract: The fossil species of Thaumatodryinus from Dominican amber are studied, and the first revision is presented with a key to the known taxa. We recognize three species, T. miocenicus Olmi, 1995, T. priscus (Olmi, 1998), comb. nov. and T. fuscescens sp. nov. The current classification of the genus and relationships between fossil and living species are discussed. Comments on the host records for Thaumatodryinus are presented.

Patching up the past one fossil at a time: A new genus and species of Eulophidae from Eocene Baltic Amber (Hymenoptera, Chalcidoidea) https://jhr.pensoft.net/article/55899/ Journal of Hymenoptera Research 79: 27-42

DOI: 10.3897/jhr.79.55899

Authors: Tiffany C. Domer, Roger A. Burks, Lars Krogmann, John M. Heraty

Abstract: A new fossil species of Eulophidae, Kressleinius celans, gen. et sp. nov., is described from Eocene Baltic amber. It does not place into any extant genera within Eulophidae due to a lack of distinctive synapomorphies. The results of a morphology-based phylogenetic analysis placed K. celans in Tetrastichinae because of features shared with several genera, including having 6 flagellomeres past the anelli, admarginal setae short, propleura diverging, and a newly described feature of the transepimeral sulcus. This represents the oldest known fossil for the largest family of Chalcidoidea in terms of described species.

Discovery and description of the first known fossil Signiphoridae (Hymenoptera, Chalcidoidea) https://jhr.pensoft.net/article/53307/ Journal of Hymenoptera Research 77: 219-226

DOI: 10.3897/jhr.77.53307

Authors: Roger A. Burks, James B. Woolley, Shroq O. Kesbeh, Devon S. Eldridge, Ana Dal Molin, John M. Heraty

Abstract: Chartocerus azizae sp. nov. is described as the first known fossil from the family Signiphoridae, based on two inclusions in the same piece of Eocene Baltic amber (36.7–48.5 million years ago). Implications of the morphology of C. azizae are discussed, indicating that it should be placed in Chartocerus.

Proterosceliopsidae: A new family of Platygastroidea from Cretaceous amber https://jhr.pensoft.net/article/32256/ Journal of Hymenoptera Research 73: 3-38

DOI: 10.3897/jhr.73.32256

Authors: Elijah J. Talamas, Norman F. Johnson, Chungkun Shih, Dong Ren

Abstract: Proterosceliopsis was erected by Ortega-Blanco et al. (2014) in their treatment of scelionid genera in Cretaceous amber from Álava, Spain. The generic description appears to have been based on specimens in which only the dorsal aspects of the mesosoma and metasoma were visible, as characters of the mesopleuron, metapleuron, lateral pronotum, and ventral metasoma were not mentioned. We here provide a comprehensive description of the genus that includes characters from throughout the body and we reinterpret some of the characters presented by Ortega-Blanco et al. (2014). Our analysis of Proterosceliopsis in the context of extant and fossil platygastroids places this group as a lineage well outside of the current families. We here designate Proterosceliopsis as the type genus of a new family, Proterosceliopsidae Talamas, Johnson, Shih & Ren, fam. nov., and describe five new species: Proterosceliopsis ambulata Talamas, Shih & Ren, sp. nov., P. nigon Talamas, Shih & Ren, sp. nov., P. plurima Talamas, Shih & Ren, sp. nov., P. torquata Talamas, Shih & Ren, sp. nov., and P. wingerathi Talamas, Shih & Ren, sp. nov. We provide a key to all presently known species in the genus. The oldest known specimen of Platygastridae s.s., in Burmese amber, is presented and compared to Proterosceliopsidae fam. nov.

Archaeoteleia Masner in the Cretaceous and a new species of Proteroscelio Brues (Hymenoptera, Platygastroidea) https://jhr.pensoft.net/article/10388/ Journal of Hymenoptera Research 56: 241-261

DOI: 10.3897/jhr.56.10388

Authors: Elijah J. Talamas, Norman F. Johnson, Matthew L. Buffington, Dong Ren

Abstract: The generic concepts of Archaeoteleia Masner and Proteroscelio Brues are expanded to accommodate two new species that are here described: Archaeoteleia astropulvis Talamas sp. n. and Proteroscelio nexus Talamas sp. n. A specimen of Archaeoteleia from Baltic amber is illustrated and discussed. Diagnoses of Proteroscelio, Proterosceliopsis Ortega-Blanco, McKellar & Engel and Bruescelio Ortega-Blanco, McKellar & Engel, a key to Cretaceous platygastroid genera with 14-merous antennae, and a key to the species of Proteroscelio are presented.

Fossil Platygastroidea in the National Museum of Natural History, Smithsonian Institution https://jhr.pensoft.net/article/5730/ Journal of Hymenoptera Research 47: 1-52

DOI: 10.3897/JHR.47.5730

Authors: Elijah Talamas, Matthew Buffington

Abstract: Platygastroid wasps preserved in Dominican amber and oil shale from the Kishenehn formation (Montana, USA) in the National Museum of Natural History are catalogued. Compression fossils in Kishenehn oil shale yield a specimen of Fidiobia, a specimen of Telenominae, and a specimen with a Scelio-type ovipositor system. Twenty-five described genera are documented from Dominican amber, all of which are known from the extant fauna: Allostemma Masner & Huggert, Aradophagus Ashmead, Calliscelio Ashmead, Calotelea Westwood, Duta Nixon, Embidobia Ashmead, Embioctonus Masner, Fidiobia Ashmead, Gryon Haliday, Idris Förster, Inostemma Haliday, Leptacis Förster, Leptoteleia Kieffer, Macroteleia Kieffer, Odontacolus Kieffer, Opisthacantha Ashmead, Parabaeus Kieffer, Paridris Kieffer, Platygaster Latreille, Plaumannion Masner & Johnson, Probaryconus Kieffer, Psilanteris Kieffer, Spiniteleia Masner, Telenomus Haliday, and Triteleia Kieffer. Fourteen of these genera do not have previously published fossil records and are here documented for the first time. Plaumannion fistulosum Talamas, sp. n., and Paridris yumai Talamas, sp. n. are described as new species. A phylogenetic analysis of Paridris including P. yumai is presented. A male specimen belonging to an undescribed scelionine genus is documented and illustrated, but not described, as the best features for circumscribing this taxon are found in the female, and monographic work on this group is currently underway by other workers. Four specimens from Baltic amber, belonging to Leptacis, Platygaster, and Sembilanocera Brues are presented for comparison to extant specimens and inclusions in Dominican amber.

Colemanus keeleyorum (Braconidae, Ichneutinae s. l.): a new genus and species of Eocene wasp from the Green River Formation of western North America https://jhr.pensoft.net/article/4727/ Journal of Hymenoptera Research 44: 57-67

DOI: 10.3897/JHR.44.4727

Authors: J. Fisher, Erika Tucker, Michael Sharkey

Abstract: A new genus and species of Ichneutinae s. l., Colemanus keeleyorum Fisher, is described from the Eocene Green River Formation in Colorado, USA. Colemanus was placed on a phylogenetic hypothesis using morphological data. Using a parsimony criterion, Colemanus is placed within Proteropini (Ichneutinae s. l.). Reconstructions of well-preserved regions (mesosomal dorsum and wings) are included. A previously described species from lower Oligocene Baltic amber is transferred to Colemanus, resulting in the new combination C. contortus (Brues, 1933).
