Often grouped with similarly plumaged species in the “grey antwren assemblage” (see M. axillaris). Close relationship to M. schisticolor and M. sunensis suggested by similarities in morphology, behaviour and vocalizations. Specimens from SW Amazonia tentatively assigned to present species by earlier authors, but identity of these requires substantiation, including further field studies and vocal and molecular analysis; may represent a distinct species. Monotypic.
Coastal SE Brazil, mainly in Serra do Mar (S Rio de Janeiro, São Paulo) and highly fragmented from SE Bahia S to extreme NE Santa Catarina; also old records from E Minas Gerais.
