A holopsenelline wasp in mid-Cretaceous amber from Myanmar (Hymenoptera: Bethylidae)

A new genus and species of the basal bethylid subfamily Holopsenellinae is described and figured from a female in Burmese amber, the first occurrence of the lineage outside of the Early Cretaceous deposits of Lebanon. Holopsenelliscus pankowskiorum gen. and sp. nov., differs from other holopsenellines most notably in the discontinuous anterior wing margin and open subdiscal cell, among other traits. The genus and species are described in full and distinguished from Holopsenella primotica Engel et al. in Lebanese amber and Cretabythus sibiricus Evans in Taimyrian amber. A key to the genera of Holopsenellinae is provided.
