Sometimes considered conspecific with M. poliopterus, but differs on account of larger size (male wing 328–346 vs 305–326) (score at least 2); much whiter secondaries, forming distinct mottled white wingpanel at rest (2); red cere and legs vs yellow cere and orange legs (3); greyer dorsal area without darker grey-brown smudging (1); and (in juvenile) more uniform underparts#R. Form argentior perhaps poorly differentiated, paleness possibly result of clinal variation. Author of original description previously given as Rislachi#R. Two subspecies recognized.
