Introduction

This small endemic genus includes two pale green species which have the lateral pronotal processes brought forward and adpressed to each other to form a single anterior pronotal horn. Both species are found in the tropical north, one in the North Kimberley bioregion of Western Australia and the other in Cape York Peninsula, North Queensland. The genus is clearly related to Sextius Stål with which it shares green coloration and reticulate venation on the tegmen.

Diagnosis

Reticulate venation like Sextius [Stål] but immediately recognisable by the two forwardly directed processes of the pronotum. Differs from Sextius also in location of ocelli, in metopidium and in anal vein 2A. Scutellum obscured by pronotum (Day 1999).

Day (1999) also provided a comprehensive description of the genus.
