The Cape Sengi is endemic to South Africa (Corbet and Hanks 1968; Skinner and Chimimba 2005). Although most 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.
