For years considered conspecific with C. semitorquata and C. curvirostris before this complex was broken into five species#R, including race benguelensis of present species. However, that arrangement suffered from uncertainty over whether race damarensis belonged with morphologically and vocally very similar benguelensis; hence benguelensis (with race kaokoensis) is reabsorbed into present species, which differs from C. semitorquata in characters given under that species, and from C. curvirostris by its shorter bill (2), reduced streaking on underparts (2) and buffier ground colour (1), but apparently narrowly sympatric in certain places (see C. curvirostris). Race gilli intergrades with nominate, and bradshawi with damarensis. Six subspecies recognized.
