Appears to be closely related to M. grisea on basis of habitat and vocalizations, also to M. unicolor and M. snowi of Brazilian Atlantic Forest, the four together termed the “Plain-winged Myrmotherula group”. They are often grouped with the “grey antwren assemblage” (see M. axillaris). Four subspecies recognized.
