Type material.

Holotype male (WAM T93/1330): northwest tip of Degerando Island, Champagny Islands, 15°20'S, 124°11'E, Western Australia, Australia, 11.VII.1988, A.F. Longbottom.

Etymology.

This species is named after Alan Longbottom, collector of the holotype and many other interesting arachnids for the Western Australian Museum.

Diagnosis.

Males can be separated from other species by having three processes of the RTA as well as a crescent-shaped conductor with a scythe shaped terminus (Fig. 17). Females unknown.
