Introduction

This endemic genus of three known species is distinctive in the fauna with its arrow-shaped head with the ocelli placed dorsally. It is uncertain whether all three species are valid and a modern taxonomic study of the genus is warranted. The genus is distributed in southeastern Australia from the far SE corner of Queensland to Tasmania.
