Range Description

The Karoo Rock Sengi is endemic to South Africa occurring in the Northern Cape Province and the northwestern edge of the Western Cape Province. The species therefore appears limited to the Nama-Karoo vegetation biome in the south-central semi-arid Karoo of South Africa. The Nama-Karoo is subdivided into Bushmanland and the Upper and Lower Karoo bioregion vegetational units (Mucina and Rutherford 2006). Based on genetic evidence, E. pilicaudus is divided into two clades (Smit et al. 2008) . Specimens from the Upper Karoo bioregion have a different genetic profile than those from the Lower Karoo bioregion. Because there are only five known locations where the new species occurs, the distribution is not well understood, although it appears to be highly restricted. It is possible that the distributions of the Cape Rock Sengi (E. edwardii) and the Western Rock Sengi (E. rupestris) do not overlap with E. pilicaudus. Within the range of the new species, it is not likely to be continuously distributed because its boulder and rock habitats are highly fragmented, thus the area encompassed by the known locations is undoubtedly greatlyexaggerated. All known locations are >1,300 m asl.
