White coastal sand dunes from Namibia, near Lüderitz, south to Hondeklip Bay, Little Namaqualand, South Africa. The type-locality given is "Angra Pequenia" [Lüderitz Bay, Namibia].[1] Mallow et al. (2003) describe the range as the transitional regions of the Namib Desert.[2] The range may extend up to 60 km inland in the Sperrgebeit of southern Namibia.[3]
This species is classified as vulnerable (VU) on the IUCN Red List for the following criteria: A2cd (v2.3, 1994).[5] This means that a population reduction of at least 20% is projected or suspected to be met within the next ten years or three generations, whichever is the longer, due to a decline in area of occupancy, extent of occurrence and/or quality of habitat, or due to actual or potential levels of exploitation. Year assessed: 1996.[6]
An account is provided by Hurrell (1981) of a bite he sustained on his left index finger. The symptoms included intense pain, pronounced swelling, discoloration and oozing of serum from the punctures. After 24 hours, a 5 mm hematoma developed at the bite site. His condition stabilized after 3–4 days with swelling and pain gradually subsiding. Healing was complete after 2 weeks with no loss of function or sensation of the afflicted digit. There was minimal local tissue damage and no systemic effects were reported. No antivenom is available for this species.[2]
