Justification
This Northern Cape endemic is known from four sites but may occur at additional sites. It has a known range of about 257 km². The full range of this species is not yet known, but the extent of occurrence (EOO) may be as large as 10 000 km² if it occurs across the Tanqua Karoo. It is a habitat specialist that is locally common. Large areas of its habitat, including three of the known sites are protected within the Tanqua Karoo National Park. It therefore qualifies for listing as Rare nationally and qualifies under the IUCN 3.1. criteria as Least Concern.
