Rationale
(Changed due to Same category and criteria)
Previously listed as Vulnerable, this species has been found in a larger area between what were previously considered to be fragmented subpopulations. It is now listed as Least Concern in view of its wide extent of occurrence and stable population.
Distribution
This species lives in mountainous areas of Namaqualand, north of the Knersvlakte and south of the Orange River, in the Northern Cape Province of South Africa. It has not so far been recorded from Namibia, although it is likely to occur there. It is found at 200-1,600 m asl. Its extent of occurrence (EOO) is estimated as 9,000 km2 with an area of occupancy (AOO) of approximately 5% of the EOO (450 km2), estimated based on availability of appropriate habitat (a variety of water bodies) within the EOO, and it is known from around 15 locations.
This species is not uncommon in proximity to water sources in its habitat.
Threats
Although its habitat is degraded by grazing pressure (including trampling at watering points), and siltation and pollution of the streams, these threats are acting on a minority of subpopulations and so are not currently considered to be very severe.
Uses and trade
There are no reports of this species being utilized.
Conservation
No conservation actions are currently prioritized for this species. It occurs in the Richtersveld National Park.
