  Type species:

   Austrodascalia evansorum Fletcher, 1988 by original designation.

Introduction

This is currently a monotypic, endemic genus. The only described species, A. evansorum Fletcher, is from the Einasleigh Uplands of North Queensland. However, there is a second undescribed species from the base of Cape York Peninsula and a female which is 50% larger than those of A. evansorum, also from Cape York Peninsula. In addition, there are two females from near Millstream in the Pilbara region of Western Australia which may represent a third species. All of the species are characterised by narrow elongate brown tegmina which resemble broken sticks.
