Endemic to South Africa, where it occurs in the western portions of the Northern Cape and adjacent extreme northern Western Cape, from the western Richtersveld in the north to the Knersvlakte and Groenriviermond in the south (Lamb and Bauer 2000, Bates et al. 2014).
The population is inferred to be stable and not fragmented, given that most of its range is not impacted by human activities.
