This species occurs only in the Eastern Langeberg Mountains in Western Cape Province, South Africa, from the vicinity of Montagu and Kogman's Kloof, eastwards through Swellendam and Grootvadersbosch Forest Reserve, probably as far east as the Gouritz River. Its altitudinal range is 215-500 m asl. Its Extent of Occurrence is less than 5,000 km2.
Habitat and Ecology
It lives in forest patches surrounded by mountain fynbos heathland outside the breeding season. Fast-flowing perennial streams are required for breeding. The tadpoles take two years to develop.
It is a locally common species.
It is not significantly threatened. Locally, there are some impacts from alien species introductions (but less in the Langeberg than some other places), a small amount of afforestation, and fires taking place too frequently.
Almost the whole range of this species is conserved in protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is less than 5,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under threat and it has a presumed large population.
It is not clear that this species is distinct from Heleophryne purcelli (L. Minter pers. comm.).
