The species grows to about 70–100 mm in length. Colouration is mainly yellowish-brown to dark brown, with the head and pincers darker.

Distribution and habitat
The species occurs along the coast of South Australia from Adelaide westwards, around the Great Australian Bight and south-west Western Australia, to Perth. It is found in coastal dunes as well as in sandy soils farther inland at the western end of its range.
