Scratching the surface of Afrotropical Dissomphalus (Hymenoptera, Bethylidae): a revision uncovering 114 new species.

The main goal of this paper is to revise the Dissomphalus genus within the Afrotropical region. Specimens were collected across seventeen countries: Benin, Botswana, Cameroon, Central African Republic, Democratic Republic of Congo, Gabon, Guinea, Kenya, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Uganda, Zambia and Zimbabwe. A total of 127 species have been identified in the Afrotropical region.

Revision of the Neotropical Genus Solepyris Azevedo (Hymenoptera, Bethylidae).

The bethylid genus Solepyris Azevedo (Scleroderminae) is studied and revised. Five species are recognized, including three previously described ones: †S. electromexicanus Brazidec and Perrichot, S.

Insights from the first phylogenomic analysis of flat wasps (Hymenoptera, Bethylidae) reveal two new subfamilies.

Despite significant advances in alpha level taxonomy in the past few decades, the higher-level phylogeny of flat wasps (Hymenoptera, Bethylidae) remains poorly explored. Herein we provide the first phylogenomic assessment of the family based on data from ultraconserved elements for 96 species in 61 genera of the family, with material from 29 countries and all biogeographic regions. Dataset cutoffs including ultraconserved element loci recovered for 50 and 70% of terminals resulted in matrices with 1513 and 451 loci, which were analysed in both parsimony and maximum likelihood frameworks.

Glutodon gen. nov. (Hymenoptera, Bethylidae), a flap-metasomed Pristocerinae from Madagascar.

Here we describe the flat wasp genus Glutodon gen. nov., and its single species G.

Revision of Pristonesia (Hymenoptera, Bethylidae, Pristocerinae), an endemic Afrotropical genus.

The Afrotropical pristocerine genus Pristonesia is revised. Seven species are recognized, one previously described species, P. nyamuragira (Benoit), and six species are described and illustrated as new: P.

Synopsis of the Neotropical Sclerodermus Latreille (Hymenoptera, Bethylidae) with description of a new species attacking human beings.

We provide a Neotropical synopsis of the genus Sclerodermus Latreille. The genus is recognized by having the antenna with 11 flagellomeres, the head globoid or nearly so, the eyes present and flat, and the clypeal median lobe strongly angled and deeply separated from the lateral lobes. The strong polymorphism of having wings is an intra- and intergeneric feature and the macropterous specimens are diagnosed by having forewings with the pterostigma slender and only the R cell closed.

Rediscovery of Kurians types of Hymenoptera at Forest Research Institute, Dehradun, India with notes on Indian bethylid fauna.

The types specimens of many taxa described by Chandy Kurian were considered lost for many years, which prevented the recognition of the species delimited by him. Fifty holotypes have been rediscovered in the National Forest Insect Collection of Forest Research Institute, Dehradun, Uttarakhand, India. Forty-five types belong to Bethylidae (Cephalonomia tritici, Chlorepyris biharina, C.

Description of two females of Leptagrion Selys (Odonata: Coenagrionidae).

In this paper, we provide taxonomic updates on the genus Leptagrion Selys: the females of L. acutum Santos and L. porrectum Selys are illustrated and diagnosed for the first time.

Synopsis of world Discleroderma Kieffer (Hymenoptera, Bethylidae).

We provide a synopsis of the genus Discleroderma, which is known only from females. The genus is easily recognized by having tubercles on metasomal tergites III-V. In this synopsis we recognized D.

New species and records of Dissomphalus Ashmead (Hymenoptera, Bethylidae) from Cerrado, Caatinga and relicts of the Atlantic Forest from northeastern Brazil.

The main goal of this paper is to study the Dissomphalus material deposited at the Coleção Zoológica do Maranhão (Maranhão, Brazil). The material was collected in six parks: Parque Nacional Chapada das Mesas, Parque Estadual do Mirador and Reserva Ecológica do Inhamum in the state of Maranhão; Parque Nacional Serra das Confusões and Parque Nacional de Sete Cidades in the state of Piauí, and Parque Nacional de Ubajara in the state of Ceará. Forty species are recognized from these six parks.

Global guide of the flat wasps (Hymenoptera, Bethylidae).

The flat wasp family Bethylidae Haliday lacks global scale literature on their alpha taxonomy. The only world revision for the family was by Kieffer in 1914 and is fully out of date and somewhat useless; the only catalog for the family was made by Gordh Móczár in 1990 and does not include hundreds of changes made since then; and the most recent world genera keys were proposed by Terayama in 2003, but do not reflect the current knowledge we have for the family. Given this scenario, we present a global guide of Bethylidae with diagnoses, taxonomic evaluation, keys, and a checklist of all their extant genera and subfamilies.

Pairs in copulation of the highly dimorphic genus Pristocera Klug (Hymenoptera, Bethylidae) from Madagascar solve taxonomic problems of male-female associations.

The main goal of this paper is to update the taxonomic information of the pairs of Pristocera Klug collected in Madagascar by A. Seyrig. Within this material twelve species are recognized, ten are new to science, all based on pairs collected in copulation, which are described and illustrated: P.

Taxonomic contributions to Ageniella Banks, 1912 (Hymenoptera: Pompilidae) from Brazil.

Ageniella Banks is the second most diverse genus in the tribe Ageniellini (Pompilidae: Pepsinae) with about 200 valid names. Ageniella is known to be paraphyletic; yet, no revision has been made. Lack of a taxonomic catalogue and of identification keys has further delayed taxonomic studies.

Review of Dissomphalus Ashmead, 1893 (Hymenoptera, Bethylidae) from Espírito Santo, Brazil, with description of twenty-one new species.

Forty-two species of Dissomphalus Ashmead, 1893 are reviewed, 21 of them are described and illustrated: Dissomphalus botocudus sp. nov., D.
