This species is represented by a lectotype from Walvis Bay and is range-restricted to the dune field of the Namib Desert in east central Namibia, where it is found from the coastline to the inland edge of the dune fields (Harrison et al. 2003). It is found at low altitude in a desert that receives extremely low rainfall but that is subject to frequent coastal mists that roll up to 100 km inland, thus reducing the annual temperature of the region. Its extent of occurrence is estimated at approximately 44,000 km2, with an area of occupancy of around 10,000 km2 based on the estimated area of dune streets.
