Santo Aleixo, Rio de Janeiro, Brazil.
Taxonomic validity questioned by various authors; was initially thought by some to be a hybrid between M. unicolor and race luctuosa of M. axillaris, and later considered possibly a variant of latter; moreover, some uncertainty over whether recent observations refer to same taxon as original type specimen. More research, including thorough analysis of recent tape recordings, is needed in order to determine its true taxonomic status. All mentioned taxa are often grouped with M. schisticolor, M. sunensis, M. minor, M. iheringi, M. behni, M. grisea, M. snowi, M. longipennis, M. urosticta and M. menetriesii as the “grey antwren assemblage”, although this grouping possibly not monophyletic. Monotypic.
