Ordo: Hymenoptera
Familia: Braconidae
Name
Pseudosteres van Achterberg, 2023 gen. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Biosteres adanaensis Fischer & Beyarslan, 2005.
Etymology
From “pseudos” (Greek for “fallacy”) and the generic name Biosteres Foerster, because it is similar to Biosteres, but differs considerably as indicated below. Gender: masculine.
Diagnosis
Hypoclypeal depression usually medium-sized, and medially ventral margin of clypeus above upper level of condyles of mandibles, but depression absent in P. riphaeus and narrow in P. adanaensis (Fig. 35); mandible with a large ventral tooth and its outer side convex (Fig. 40), mandible not twisted apically and second tooth clearly visible; notauli largely absent posteriorly (Fig. 36); medio-posterior depression of mesoscutum present; scutellum punctate medio-posteriorly; precoxal sulcus either absent, as a smooth and narrow suture or depressed and distinctly crenulate; precoxal sulcus without a second sculptured sulcus below; vein m-cu of fore wing slightly converging to vein 1-M posteriorly (Fig. 34) or parallel; vein r more or less angled with vein 3-SR of fore wing; vein 3-SR of fore wing 1.2–1.6× longer than vein 2-SR; vein m-cu of fore wing antefurcal or interstitial; pterostigma elliptical (Fig. 34) or elongate triangular; hind tibia without oblique carina basally; dorsope present (Fig. 41); hypopygium of ♀ truncate.
Distribution
Palaearctic: five species.
Notes
Most species are similar to the genus Biosteres Foerster, 1863, but differ by having a large ventro-basal tooth or lobe and in part of species also by the presence of a medium-sized hypoclypeal depression. Members of Opiostomus Fischer have also the mandibles basally widened and the dorsope developed, but the mandible is distinctly twisted medially, the second submarginal is much longer and the scutellum is smooth posteriorly (but punctate in O. leptostigma (Wesmael)).
