Insecta, Hymenoptera, Bethylidae: range extension and filling gaps in Madagascar

Abstract

Bethylidae are cosmopolitan wasps, with about 100 valid genera and about 2,400 valid species around the world, with 39 genera recorded from the Afrotropical region. This study aimed to determine the genera of Bethylidae occurring in Madagascar. The specimens were collected in Madagascar with several traps. A total of 18,915 specimens were obtained and 27 genera recognized. Nine of them are already recorded from Madagascar: Epyris, Glenosema, Goniozus Laelius, Pilomesitius Pristocera, Rhabdepyris, Sclerodermus, Sulcomesitius, and 18 genera are recorded for the first time: Alloplastanoxus, Apenesia, Bethylus, Cephalonomia, Diepyris, Dissomphalus, Formosiepyris, Heterocoelia, Holepyris, Kathepyris, Odontepyris, Parascleroderma, Plastanoxus, Prorops, Prosapenesia, Pseudisobrachium, Trachepyris and Tuberepyris. The only genus not founded was Messoria.
