Introduction
This endemic genus of 25 species is widely distributed across all states of Australia although there are no confirmed records from the Australian Capital Territory. Most species seem to be restricted to coastal areas although there are species from western Queensland and inland parts of southern Western Australia. The genus was reviewed by Webb (1983) who recognised 24 species, the additional species being added by Fletcher (2007). None of the species is known as a pest.

Diagnosis
The anteclypeus and the frontoclypeus are wide and almost flat and the maxillary plates are narrow and depressed below the level of the lora. The frontal sutures are directed outwards apically and the ocelli are sunk in slight depressions. The crown is wide and the coronal suture very short. The hind tibia has two spines set on prominent bases in a row containing four other spines (Evans 1941, as Macrocerus).
A more detailed redescription is provided by Webb (1983).
