  Type data:

   Holotype WAM 34380 ♂ (coll: R.P. McQuillan, 4.viii.1995), Arrowsmith River, Wilson Reserve, Western Australia.

Introduction

This species has a wide distribution from near Geraldton, Western Australia, to SE South Australia and from a single locality in New South Wales. The locality in New South Wales was given by Löcker et.al. (2006) as "Conan, NSW" but there is no locality with that name. A search through the ASCU database has revealed that other insect specimens matching the collector and date of this specimen were collected at Cowan, NSW which is a locality north of Sydney.
