  Type data:

   Holotype ASCU ♂ (coll.: v.1966, K. Moore. , ex J.W. Evans collection, donated 1986), Einasleigh River, Queensland.

Introduction

This species was based on a male and three females collected from Melaleuca sp. (Myrtaceae) in the Einasleigh Uplands of North Queensland. Although it has not been observed in life, it is presumed that its cryptic coloration and elongate knobbly tegmina make it appear like a short broken stick or piece of dead leaf.
