  Type species:

   Austroagalloides karoondae Evans, 1936 by original designation.

Introduction

This is the only genus in the subfamily. Evans (1938) considered that the variation found between the species might warrant dividing the genus but there are difficulties due to sexual dimorphism and other intraspecific variation that make it hard to define generic groupings clearly. Evans therefore retained all the species in Austroagalloides.

Diagnosis

The head lies in three different planes so that the vertex bearing the ocelli and the hind margin of the frons is more or less vertical and at right-angles to the anterior portion of the head. The ledges overhanging the antennae are pronounced, the clypeus usually extends beyond the maxillary plates and the hind border of the frons is generally obscure. The eyes are large and prominent, so that the head, including the eyes, is wider than the pronotum at the base, and the crown from above, between the eyes, is broad and of even width throughout. The tegmina, which are long and narrow, have either a very narrow appendix or no appendix at all, and the veins have raised dots, either lying alongside them or on the veins themselves. The hind tibiae usually have an armature of weak spines, seldom set on enlarged bases. The male genitalia have large pygophores, and parameres which are half the length of the subgenital plates (Evans 1936).
