Molecular data indicate that this species is closest to C. viridis and C. bengalensis#R#R. Sometimes regarded as conspecific with C. toulou, but voices of the two differ; has also been considered possibly conspecific with C. bengalensis, but marked differences in morphology and, apparently, vocalizations. Proposed races caeruleiceps (S Ethiopia) and wahlbergi (NE South Africa) considered undiagnosable. Monotypic.
