Until recently was considered conspecific with M. momota (and M. coeruliceps, M. subrufescens, M. bahamensis and M. aequatorialis), but (assuming that races goldmani and exiguus are divergent in only minor ways) differs from latter four in characters given under those species, and from M. momota in its clearly distinct song in which the two notes are separated by a much longer interval (2; possibly 3), broad black vs narrow or non-existent hindcollar (adjacent to posterior diadem) (2), distinct black terminal third of racquets vs indistinct dusky border (2), and absence of rufous in occiput (1)#R. Specific name sometimes misspelt lessoni#R. Three subspecies currently recognized.
