The flat wasp family Bethylidae Haliday lacks global scale literature on their alpha
taxonomy. The only world revision for the family was by Kieffer in 1914 and is fully out of …

The world fauna of the flat wasps (Bethylidae) is represented by about 3,000 valid species.
The skeletal morphology of bethylids is still not adequately understood and the terminology …

The most widely recognized hymenopterans–ants, bees, and wasps or hornets–have long
been part of art, ritual, and folklore worldwide. Both extant and extinct Hymenoptera were …

The subfamily Epyrinae is the most common in the bethylid fossil record. Its geological
history ranges from the Eocene to the Pleistocene, and it is the only subfamily that has no …

We apply integrative taxonomy to solve a historical taxonomic impasse in a flat wasp group
(Hymenoptera, Bethylidae). The phylogeny of Epyrinae is inferred with parsimony analyses …

Some authors in the past based their conclusions about the limits of the metapostnotum of
Chrysidoidea based on the position of the mesophragmo-metaphragmal muscle, rather than …

Despite significant advances in alpha level taxonomy in the past few decades, the higher‐
level phylogeny of flat wasps (Hymenoptera, Bethylidae) remains poorly explored. Herein …

A new extinct bethylid wasp attributable to the subfamily Scleroderminae is described from
upper Eocene amber found at the Voronki mine in the Vladimirets District of the …

Abstract The flat wasp Apenesia Westwood is one of the largest genera in Pristocerinae with
190 species worldwide. The lack of a single diagnostic morphological character has resulted …

The flat wasps, Bethylidae, are cosmopolitan and one of the most diverse families of
Chrysidoidea. Bethylidae have 2,920 described extant species and almost 90 fossil species …
