Genetic and morphological analyses indicate that this species and M. ignota, M. ambigua, M. sclateri, M. surinamensis, M. multostriata, M. pacifica, M. cherriei, M. klagesi and M. longicauda represent a monophyletic group (the “streaked antwren assemblage”). Present species is closely related to M. ignota (which see), and previously treated as conspecific. Possibility of geographical variation requires investigation. Monotypic.

Distribution:

C & E Colombia (base of Andes S from Meta to E in Guainía, Vaupés and Amazonas), E Ecuador, E Peru, S Venezuela (Bolívar, Amazonas), the Guianas, Amazonian Brazil (E to R Tocantins, S to N & W Mato Grosso) and NW & NE Bolivia.
