Taxonomic additions to the pelecinid wasps (Hymenoptera, Pelecinidae) of the 'mid-Cretaceous' Burmese amber

A new species of pelecinid wasp, Eopelecinus inopinatus sp. nov., is described and figured from Cenomanian Burmese amber based on a single female specimen. Additionally, the examination of a new, well preserved specimen of Zoropelecinus periosus Guo, Shih & Ren 2016, allows to emend the diagnosis of this species. These discoveries confirm that Pelecinidae were clearly highly diverse during the Cretaceous. We provide a list of Eopelecinus species with their respective metasomal ratio.
