Three new female Aptenoperissus from mid-Cretaceous Burmese amber (Hymenoptera, Stephanoidea, Aptenoperissidae): Unexpected diversity of paradoxical wasps suggests insular features of source biome
Abstract
Three new female wasps of the family Aptenoperissidae from the mid-Cretaceous Burmese amber are described as Aptenoperissus magnifemoris Rasnitsyn & Öhm-Kühnle, sp. nov., A. etius Rasnitsyn & Öhm-Kühnle, sp. nov., and A. pusillus Rasnitsyn & Öhm-Kühnle, sp. nov., assigned to the genus Aptenoperissus Rasnitsyn & Poinar, 2017. Features of the currently and previously described Aptenoperissidae indicate a high diversity of the group in the mid-Cretaceous fauna of Myanmar and suggest its possible insular nature; this is supported by the general characteristics of the fossil assemblage of Burmese amber.
