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, & DAG;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 & DAG;Pterosclerogibba Olmi as a new junior synonym under Goniozus Forster, in the new combination & DAG;Goniozus antiquus (Olmi). Additionally, the third species of Beth-ylinae known from Dominican amber, & DAG;Goniozus respectus Sorg, is diagnosed and illustrated with color im-ages of the holotype. An identification key to the species of Bethylinae from Dominican amber is provided.
