Habitat and Ecology
Occurs in the coastal dune belt and adjacent sandy areas in Strandveld Succulent Karoo (Succulent Karoo biome) of the Namaqua coastal plain.

Red List Criteria
Until recently known only from a single location, but recorded from a second location near Groenriviermond in 2003; this suggests that the range of this species is more widespread than previously recognized. The extent of occurrence ie estimated to be just under 5,000 km2 and area of occupancy is estimated to be 32 km2(assuming a grid cell area of 16 km2). Dramatic habitat alteration owing to mining of coastal sands for alluvial diamonds and heavy metals could be impacting on the coastal dune habitats of this species, as this has been identified as a threat toEremitalpa granti(Smithers 1986) with which this species coexists, and large-scale alluvial diamond mines occur at Hondeklipbaai (about 60 km from the Groenriviermond subpopulation) and are undergoing expansion. Habitat alteration owing to the erection of wind farms near the type locality is a potential but localized threat. The species is therefore confirmed as Endangered under criterion B1ab(iii)+2ab(iii).

This species is extremely rare even at the two locations where it is known to occur. No quantitative data are available.
Dramatic habitat alteration owing to large-scale mining of coastal sands for alluvial diamonds and heavy metals could be impacting on the coastal dune habitats of this species, as large-scale alluvial diamond mines occur at Hondeklipbaai (~60 km from the Groenriviermond subpopulation) and undergoing expansion. However, the extent and impact of this potential threat is unknown. Habitat alteration associated with the establishment of wind farms near the type locality, and tourism developments along the west coast may pose additional threats.
Occurs near the Groenrivier mouth in Namaqua National Park. Research is needed to establish distribution limits and to gather basic data on natural history of this species.
