Name
Karaops toolbrunup Crews & Harvey, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype female (WAM T76592): Stirling Range National Park, Toolbrunup, 34°23'24"S, 118°03'14"E, scree slope, Western Australia, Australia, 5.IV.2004, M.S. Harvey, J.M. Waldock, K. Edward, C. Poustie, under rocks. Paratype: same data as for the holotype, 1♂ (WAM T62231).
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).
