Abstract
A new family of stephanoid wasps is established based on Cretaceous amber inclusions and rock imprints. Ohlhoffiidae fam. nov. comprises four species in three genera: Ohlhoffia robusta gen. et sp. nov., and Myanmephialtites bashkuevi gen. et sp. nov., which are newly described and figured from mid-Cretaceous amber of northern Myanmar; and Cretephialtites pedrerae Rasnitsyn & Ansorge, 2000, and C.(?) hispanicus (Rasnitsyn & Martínez-Delclòs, 2000) comb. nov., transferred here from Karataus hispanicus, both from the Barremian of Spain. A key to the genera of the family is proposed, and we also discuss the shifting proportion of non-aculeate wasps between the Early Cretaceous and Cenozoic.
