Euoplos variabilis

Euoplos variabilis, also known as the Mount Tamborine trapdoor spider, is a species of mygalomorph spider in the Idiopidae family. It is endemic to Australia. It was described in 1918 by Australian arachnologists William Joseph Rainbow and Robert Henry Pulleine.

Distribution and habitat
The species occurs in the mountainous Scenic Rim region of south-eastern Queensland and northern New South Wales, in tall open forest and closed forest habitats. The type locality is Tamborine Mountain.

Behaviour
The spiders are fossorial, terrestrial predators. They construct burrows with thick, plug-like trapdoors in bare soil patches on the forest floor, especially on banks and slopes.
