Cataxia babindaensis, also known as the strawberry trapdoor spider, is a species of mygalomorph spider in the Idiopidae family. It is endemic to Australia. It was described in 1969 by Australian arachnologist Barbara York Main.
This is a relatively large species, with body lengths of up to 45 mm. The spiders have a deep red carapace and legs, and a banded abdomen.
The species occurs in north-eastern Queensland in closed forest habitats. The type locality is The Boulders National Park near Babinda.
The spiders are fossorial, terrestrial predators that construct burrows with soft trapdoors in wet, unlittered soil, or on embankments.
