Sometimes placed with O. frontalis, O. pulchella and O. jelskii in a separate genus, Silvicultrix, but genetic and anatomical data indicate that this would make present genus paraphyletic. All four form a superspecies. Described race meridana (from Mérida, in Venezuela) considered indistinguishable from nominate; cajamarcae (from Cajamarca, in Peru) synonymized with gratiosa. Five subspecies recognized.
