Revision of Bethylinae from Dominican amber, with description of a new genus (Hymenoptera, Bethylidae)

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.
