“…Later the genus was defined as having the aedeagus divided into ventral and dorsal laminae (Azevedo, ,b,c, , , ). Since then, several species of Dissomphalus have been described with variations in the presence/absence of tergal processes (see, e.g., Alencar & Azevedo, ; Mugrabi & Azevedo, and Colombo & Azevedo, ). Characteristics such as body robust, metasoma wide and short, clypeus tridentate and aedeagus divided into two distinct laminae are present in Dissomphalus and dissomphaloides .…”

The flat wasp Apenesia Westwood is one of the largest genera in Pristocerinae with 190 species worldwide. The lack of a single diagnostic morphological character has resulted in many distinct ground plans within Apenesia. Some authors have suggested Apenesia as polyphyletic. Here we aimed to investigate and delimit the genus based on morphological and molecular data. We analysed 163 morphological characters on tnt using ‘traditional search’, whereas Bayesian (BI) and maximum likelihood (ML) inferences were performed on 1553 concatenated nucleotide base pairs from COI and 28S sequences. Apenesia was recovered as polyphyletic in all analyses with up to 10 different lineages spread throughout the tree. We mapped female morphological characters onto the molecular tree to enlighten morphological evolution in the apterous females. Based on our morphological and molecular analyses, and on the taxonomic revision of holotypes and specimens, we propose six new genera in the Pristocerinae and revalidate the generic status of two: Acrenesia gen.n., Austranesia gen.n., Cleistepyris stat. rev., Dracunesia gen.n., Eleganesia gen.n., Epynesia gen.n., Pristonesia gen.n., and Propristocera stat. rev. We also propose four new generic synonymies: Neoapenesia syn.n. under Apenesia, Dipristocera syn.n. under Cleistepyris, Afrocera syn.n. and Neopristocera syn.n. under Propristocera. At the species level, we indicate Apenesia minor syn.n. under Propristocera tagala. In all, 162 new combinations, eight reinstated combinations and one new name to avoid homonymy are proposed. Apenesia is now defined as flat wasps having males with the mesoscutum gibbous, the genitalia with the paramere narrow and densely hairy, and the aedeagus with the ventral apical lobe elliptical and covered with lumps. Females of Apenesia can be distinguished from other Pristocerinae by having the head wider than the mesosoma, the antennae short, the mandible long, and the clypeus surpassing the toruli in the frons. This study reinforces the difficulties in defining Apenesia and other Pristocerinae genera.

“…At least the Thai, African, and Neotropical species of Dissomphalus have a small median concavity on the hypopygium, unlike Dissomphalus schubnelli n. sp. (Azevedo 1999(Azevedo , 2003(Azevedo , 2010Mugrabi & Azevedo 2013). Nevertheless it was not possible to compare D. schubnelli n. sp.…”

Dissomphalus schubnelli n. sp., first fossil of the extant pristocerine genus Dissomphalus Ashmead, 1893, is described from the Earliest Eocene amber of Oise (France). This genus comprises 424 extant species distributed worldwide (except Antarctica). Dissomphalus schubnelli n. sp. is the third described Pristocerinae Mocsáry, 1881 from Oise amber, showing that this subfamily was probably already very diverse at that time. RÉSUMÉPremier fossile du genre actuel de guêpe plate Dissomphalus Ashmead, 1893 (Hymenoptera: Bethylidae: Pristocerinae). Dissomphalus schubnelli n. sp., premier fossile du genre actuel Dissomphalus Ashmead, 1893 de la sous-famille Pristocerinae Mocsáry, 1881, est décrit dans l'ambre de l'Éocène basal de l'Oise (France). Ce genre comprend 424 espèces actuelles réparties dans le monde entier (sauf l'Antarctique). Dissomphalus schubnelli n. sp. est le troisième Pristocerinae décrit de l'ambre de l'Oise, ce qui montre que cette sous-famille était probablement déjà très diversifiée à cette époque.
