Usually considered conspecific with O. cinnamomeiventris and O. nigrita, but differs from latter in characters outlined under that species. Differs from former in its slaty vs deep chestnut (bay) belly (3); longer tail (effect size for males 6.4, score 3); markedly different song, being a longer (score 2), flatter but slightly descending whistle vs a short up-and-down high whistle, sometimes buzzy (hence much narrower frequency range, 600–1900 Hz vs 2000–3500 Hz; score 2)#R. Two subspecies recognized.
