Diagnosis

The head and thorax are punctate. The anteclypeus is pear-shaped and the maxillary plates are largely concealed by the lobe-like lora. The subgenal sutures are transverse and the genae swollen. The postclypeus is parallel-sided and flat. The antennal bases lie in circular depressions and the supra-antennal ledges are raised slightly above the level of the face. The frontal region is slightly medially depressed. The crown, which has an obscure median ridge, slopes slightly laterally. In forms lacking hind wings, ocelli are present but functionless. The narrow tibiae are parallel-sided. The tegmina, which are slighly punctate, have distinct venation. In the male genitalia the pygophores narrow posteriorly and are continuous ventrally with the ninth sternum; the aedeagus is hook-shaped, the parameres long and hammer-shaped apically and the subgenital plates broad (Evans 1977).
