  Type data:

   Holotype SAMA ♀ (coll.: A. Brumby), between Everard Ranges, South Australia, & Warburton Ranges, Western Australia.

 

Introduction

This unusual and distinctive denizen of the outback is sexually dimorphic in head structure with the male head being triangular and anteriorly rounded while the female head is narrowly produced to a point. The original description of the genus (Evans 1937) described the head as being triangular in shape as seen from below and Evans (1981) noted that the head of the female was narrowly produced but neither author commented on the dimorphism. The species has been recorded in Western Australia and the Northern Territory with specimens from the Musgrave Ranges in the NW corner of South Australia. A single specimen from Queensland (no further details) is in the UQIC. The type locality is given as being between the Everard Ranges in South Australia and the Warburton Ranges in Western Australia but these two ranges are about 600 kms apart.
