P. L. Sclater, 1858,
Río Ucayali, Peru.
Member of the “streaked antwren assemblage” (see M. brachyura). Considered a sister-species of M. surinamensis, and until recently treated as conspecific with that and with M. pacifica, but vocal and plumage characters indicate three separate species#R. Differs from M. surinamensis mainly in female plumage (e.g. thin malar stripe, extensive thin streaking below) and in voice (e.g. no rattle call). Monotypic.
Locally in SE Colombia, S Venezuela (extreme W Amazonas), and from E Ecuador and NE & E Peru E across C Brazil (E to W Maranhão and N Tocantins, extending N of R Amazon only in area W of lower R Negro and also NE of Manaus) and S to Mato Grosso and NW & NE Bolivia.
