Completely adapted to cave living, it is blind and totally lacks pigmentation, giving it a creamy white appearance.

The species is closely related to spiders found in forests of Southern Australia.

First photo of the N37 cave spider discovered and photographed by Bill Crowle under the cairn built at the end of N37, (Mullamullang).

Two miles underground along a large passage of many rockpiles, sanddunes and lakes, and about 300 ft under the surface.

The species name is derived from Mullamullang, a cave system in the Nullarbor Plain of Western and Southern Australia.
