Until recently considered conspecific with C. mediocris and C. usambaricus, but molecular evidence invoked to produce split#R; differs from latter in characters given under that species. Differs from former in its song with higher number of different notes (2), and longer notes (excluding introductory notes) (2) which reach lower frequencies (ns[2])#R; broader red breastband (1); considerably darker belly (2); darker blue uppertail-coverts (2); female without paler yellowish mid-belly (ns[1]). Forms very narrow hybrid zone with C. moreaui, with further intergradation prevented by divergent songs#R. Two subspecies recognized.
