Distribution and habitat. This species is endemic to South Africa and Namibia ( Fig. 172 View FIGURES 172–177 ). In South Africa, the range encompasses the northern part of Namaqualand and extends eastwards to include the northern portion of the Nama Karoo Biome. In Namibia, the range includes the south-western portion of the Namib Desert. The habitats in these areas are characterised by extreme aridity, although the area along the coast is more humid and is characterised by winter rains and succulent vegetation, while the Nama Karoo region is typified by summer rain and a Karoo vegetation type.
