Dolichochorus ( Fig. 1 ) can be recognised by: - the long face and clypeus, with the latter as high as wide ( Fig. 2 ); - the rather small fore wing areolet ( Fig. 3 ). - the longitudinally striate postpetiole of the first metasomal tergite ( Fig. 5 ); - complete lateral longitudinal carinae on the first tergite ( Fig. 5 ). Unlike most mesochorines, the claws of Dolichochorus are simple (claws can be pectinate or simple in Mesochorus ). In common with many mesochorines, the apex of the fore tibia has a distinct tooth on the outer edge, which invites confusion with Ctenopelmatinae ; although no ctenopelmatines possess all of the diagnostic features of Mesochorinae , many Perilissini have deep, fenestrate glymmae, with the clypeus poorly separated from the face, and a few have needle-like ovipositors or male parameres elongate, although in neither case developed to the same degree as in Mesochorinae .
