All members of genus with exception of C. chuana formerly treated as a single species, but recent research indicates that they are genetically, morphologically and vocally distinct. Present species and C. curvirostris appear to be sister-species (ranges apparently separated by Cape fold mountains, but boundary in Gouda-Tulbagh area not well known), and genetic data suggest that they are closely related to C. semitorquata. Possibly overlaps in range with C. subcoronata in Breede Valley. Monotypic.

Distribution:

Agulhas Plain and Breede Valley, in Western Cape, South Africa.
