Cataxia maculata is a species of mygalomorph spider in the Idiopidae family. It is endemic to Australia. It was described in 1914 by Australian arachnologist William Joseph Rainbow.
The species occurs in eastern Queensland, in the EidsvoldâÂÂProserpine region, in brigalow and vine thicket open forest habitats. The type locality is the upper Burnett River.
The spiders are fossorial, terrestrial predators which construct burrows with wafer-like trapdoors.
