Rationale
(Changed due to Same category and criteria)
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
Distribution
This species occurs in the Upland Succulent Karoo biome, from Nuwerus, just north of the low-lying Knersvlakte, in the Northern Cape Province of South Africa, north to the Hunsberg in Namibia. It is absent from a narrow strip along the coast.
It appears to occur in fairly large populations, but it is seldom encountered due to the low numbers of days per year that it is active (as a result of the low rainfall), and the poor collecting effort in its range.
Threats
Some populations are probably being impacted by mining for copper and quarrying for granite. Otherwise, it is probably not facing any threats.
Uses and trade
There are no reports of this species being utilized.
Conservation
It occurs in the Richtersveld Contractual National Park and in the Goegap Wildflower Reserve. Its presence in the Namaqualand National Park and Ai-Ais Fish River Canyon Trans-frontier National Park (in Namibia) is unconfirmed but likely.
