Widespread and endemic to South Africa, where it occurs in two allopatric subpopulations (Bates et al. 2014). One subpopulation is in the Western and Eastern Cape, where it occurs mainly in Fynbos and Grassland Biomes, but with at least one record each in Forest (Tsitsikamma, see Branch 1990) and Nama-Karoo Biomes. The other subpopulation is centred around the montane grasslands of the Drakensberg, KwaZulu-Natal, and could possibly occur in eastern Lesotho although there are no records from there.
This species occurs in many protected areas across its wide range. Although Tetradactylus seps is apparently common in the Western Cape, the large-scale destruction of fynbos habitat in this region is of concern (see Le Roux 2002, Jonas et al. 2006, Rouget et al. 2006) so improved information on the species occurrence in this area would be useful. This species is under far less pressure in the Eastern Cape and KwaZulu-Natal provinces. However, if the putative subspecies T. s. laevicauda in KwaZulu-Natal proves to be a valid taxon, it will require a separate assessment.
