Hitherto considered conspecific with M. galbinus, but differs in slightly paler, greyer olive on all upperparts and breast (1); marginally brighter yellow on belly (ns); and highly distinctive song, a seemingly continuous note, in fact many very short (score 4) and very rapid (4) notes, oscillating in pitch#R. Differs further from adjacent (and parapatric or near-parapatric) race hederaceus of M. galbinus in its slightly smaller size but with notably smaller bill (at least 1). Monotypic.
