Aulacus striatus, copyright Jesper Lund.

Belongs within: Evanioidea.
Contains: Gasteruption.

The Aulaciformes are a clade of parasitoid or larval predatory wasps characterised by the absence of the jugal lobe in the hind wing, fusion of the first and second metasomal terga, sexually dimorphic antennal segmentation, and elongate propleuron, and rigid attachment of the pronotum and mesepisternum (Grimaldi & Engel 2005). Members of the Aulacidae have the metasoma separated from the metanotum by more than the anterior width of the first metasomal tergite whereas Gasteruptiidae have the metasoma and metanotum closer together (Naumann 1991).
