A new genus and species of bethylid wasps is described and figured from a female preserved in Early Cretaceous (Barremian) amber from Lebanon. Holopsenella primotica, new genus and species, is distinguished from other bethylids and segregated into a new subfamily, Holopsenellinae, along with Cretabythus sibiricus Evans in Late Cretaceous (Santonian) Taimyrian amber. Holopsenellines are perhaps basal within the family, representing a stem group to other Bethylidae, and, if so, those features shared with the coeval Lancepyrinae suggest a basal position for that lineage as well. In addition, Lancepyris alavaensis Ortega-Blanco and Engel in Early Cretaceous (Albian) amber from northern Spain is considered generically distinct from the type species of the genus, L. opertus Azevedo and Azar in Lebanese amber, and is transferred to the new genus, Zophepyris, resulting in the new combination, Zophepyris alavaensis (Ortega-Blanco and Engel). The genus Archaepyris Evans, currently considered as incertae sedis within the family, is transferred to Lancepyrinae mostly because it shares the same groundplan traits with Lancepyris.
