Type material.

Holotype male (WAM T55002): Drysdale River Station, 15°42'S, 126°23'E, Western Australia, Australia, late 1995, T. Anders.

Etymology.

This species is named for the late Keith Longbottom, collector of many interesting arachnids for the Western Australian Museum.

Diagnosis.

Males can be differentiated from other species by having an RTA with three processes, a crescent shaped conductor with a medial quadrangular lateral projection, and a MA that is directed distally (Fig. 19). Females unknown.
