Formerly considered close to, and even conspecific with, M. biarcuata, but differs in both adult and juvenile plumages. Geographical variation appears slight, but poorly documented; race grisior often considered synonymous with nominate. Proposed race obscurior (described from a single specimen taken SW of Sola de Vega, in SW Oaxaca) appears to differ little from rubricata, with which it is synonymized. Three subspecies provisionally recognized.
