Diagnosis

The anteclypeus is flat anteriorly and steeply convex posteriorly. The frontoclypeus is narrow and convex anterior to the antennae; posterior to the antennae the face is evenly rounded. The maxillary plates are narrow and emarginate, the eyes large and the apices of the frontal sutures directed inwards. The crown is wide and the coronal suture distinct. The hind tibia has one spine set on a prominent base in a row containing four other spines (Evans 1941).

This genus can be distinguished by the steeply convex clypellus and broad second valvulae of the ovipositor with numerous very fine teeth (Webb 1983).
