Cataxia cunicularis is a species of mygalomorph spider in the Idiopidae family. It is endemic to Australia. It was described in 1983 by Australian arachnologist Barbara York Main.[1]
The species occurs in north-eastern Queensland in mountainous areas with closed forest habitats. The type locality is North Cedar Creek, between Atherton and Ravenshoe.[1]
The spiders are fossorial, terrestrial predators. They construct burrows with collar-like entrances, without trapdoors.[1]
