Western Australia. 1/0/0, Stream El Questro Gorge, El Questro Homestead, The Kimberley, 15-ix- 1998.

Remarks. A species known previously known only from two sites in Queensland. The heavy seta of IV-leg-4 as illustrated by Cook (1986) differs from my specimen. Cook’s specimen has a truncated heavy seta, my specimens have a heavy seta with a small tooth. This might the result of a different position in the slide. More material must clarify these differences. Here reported for the first time from Western Australia.
