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).
