Distribution

Cacosternum parvum (previously C. nanum parvum) occurs along the Drakensberg escarpment in South Africa. In South Africa it is also found from the northern parts of Eastern Cape Province but appears to have its stronghold in KwaZulu-Natal, and it is also found in Swaziland (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).

Morphology

This species vies with C. striatum for the title of the smallest frog in South Africa. Its small size reflects a marked trend in the genus towards size reduction in high-altitude forms (Text from Minter et al., 2004, © SI/MAB Biodiversity Program).
