Type material.

Holotype male (WAM T55001): Bush Bay, site BB3, 25°04'40"S, 113°42'37"E, Western Australia, Australia, 16.I-23.V.1995, P.L. West et al., pitfall. Paratype: 1 female, same data as holotype (WAM T76700).

Etymology .

The specific name comes from the Yinggarda word karrawarla, meaning spider in the language of the indigenous Yinggarda people of the region. This name is to be treated as a noun in apposition.

Diagnosis.

Males can be differentiated from other species by having a palpal conductor with a long, fleshy terminal process (Fig. 39). Females can be distinguished from other species by having distinct lateral lobes, and a bilobed sclerotized area covering the copulatory openings in the upper third of the epigynal plate (Fig. 41).
