This species occupies rocky habitats, often with many large boulders and many crevices, and its habitat association and genetics are further discussed by Smit et al. (2007a,b).

The Cape Sengi is endemic to South Africa (Corbet and Hanks 1968, Skinner and Chimimba 2005). Although many older distribution maps show it as having two disjunct areas of occurrence, recent data indicate that it is continuously distributed (Stuart and Stuart 1991, Friedman and Daly 2004). It has not been recorded in Namibia, and is not suspected to occur north of the Orange River.

The species occurs in protected areas, but no details have been documented or assembled. Because of the very minor conservation problems facing this taxon, no conservation measures are needed or recommended at present or in the foreseeable future.
