Introduction

This genus of six species is distributed from New Guinea down the eastern coastline of Australia to Victoria. The species are mainly dark glossy species with pale markings and with a hunched appearance created by the declivous head and pronotum and the short apically overlapping tegmina.

Diagnosis

On the face of the head the clyepus is flat, excepting posterolaterally. The crown is declivous and the convex apical half is transversely striated and approximately at right angles to the face. Coronal and postfrontal sutures are present and the ocelli are adjacent to the latter midway between the coronal suture and the eyes. The pronotum, which is finely transversely striated, widens slightly posteriorly. The extensive appendix of the tegmen does not form a continuous curve with the costal margin. In the ♂ genitalia, the 9th sternum is approximately rectangular and the basal connective is longer than the parameres. The laterally flattened aedeagus has one, or more, dorsally directed lobes (Evans 1972).
