Type material.

Other material examined.

AUSTRALIA: Western Australia: Stirling Range National Park, Toolbrunup, 34°23'22.9"S, 118°03'12.8"E, 7.II.2009, S.C. Crews, under rocks on scree slope, 3♀, 1♂, 3 immatures (WAM T97234-T97240).

Etymology.

The specific epithet refers to the type locality, which means 'drizzle carrier’ in the indigenous Nyoongar language. The name is to be treated as a noun in apposition.

Diagnosis.

This species can be separated from most others by having 4 teeth on the cheliceral promargin, and from Karaops francesae sp. n. by genitalic characteristics. In the male, the cymbium is pointed distally, and the base of the embolus extends to the basal margin of the cymbium (Fig. 71). In the female, epigynal pockets are present and the sperm ducts are not coiled (Figs 69-70).
