Rationale
(Changed due to Same category and criteria)
This is an endemic taxon from the Northern Cape Province, South Africa (EOO 1 330 km<sup>2</sup>) that is known from four locations that are potentially threatened by the combined impact of drought (associated with climate change), overgrazing and abstraction of underground water. The Kalahari region is one of the areas of South Africa that is experiencing the most significant changes in temperatures, a trend attributed to climate change. The taxon thus qualifies globally under the IUCN criteria as Vulnerable under criterion D.
Distribution
Endemic to the Northern Cape Province in South Africa, from Witsand Nature Reserve to the western base of the Langberg, near Postmasburg, and north to as far as the south-eastern parts of the Tswalu Game Reserve along the Korannaberg east of Hotazel.
There are currently no significant threats to this taxon. However, the habitat occurs mainly above subterranean aquifers, and over-extraction of ground water, together with drought, overgrazing and climate change, could have serious consequences for the taxon. There are two subpopulations, both located in nature reserves, where the habitat is protected.
Conservation
Parts of the range of the species are conserved in the Witsand Nature Reserve, but better conservation would be achieved if part of the Langeberg was incorporated into the reserve.
