Description

This remarkable species of Spiny Trapdoor Spider (Cataxia) is found in sandy areas of SA’s Adelaide plains. This species probably represents the missing like between the South-West WA bolganupensis species group and the Cataxia from the eastern states. Before the discovery of this species, Cataxia was not known from SA.

They arrange grass stems and sticks in a radial fashion around the burrow entrance, which can be as deep as 70cm in places. These are small trapdoors, growing to about 20mm in length. They have orange areas on the legs and the abdomen is purple-hued and striped.
