Justification
A localized taxon, known from one location where it is potentially threatened by habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Namaqualand, between Kleinsee and Springbok.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Namaqualand Heuweltjieveld
Description
Sandy plains in Namaqualand Heuweltjieveld.
Threats
There is extensive open-cast mining in the area where this taxon occurs, and it is potentially threatened by habitat loss to mining. Large parts of Namaqualand is also heavily overstocked with livestock, which is causing ongoing degradation of arid shrublands. At present grazing however does not appear to be impacting the population.
Population

This recently discovered taxon is currently known from a single, small, but healthy subpopulation. It is likely that other, still undiscovered subpopulations exist, as its habitat is still relatively poorly explored. It is however unlikely to be widespread and common, as no other collections of this taxon are known.
