Subspecies
Forms a superspecies with Band-tailed Antwren (Myrmotherula urosticta). Other relationships uncertain, but appears closely related to Grey Antwren (Myrmotherula menetriesii). The three are often grouped with White-flanked Antwren (Myrmotherula axillaris), Slaty Antwren (Myrmotherula schisticolor), Rio Suno Antwren (Myrmotherula sunensis), Salvadori's Antwren (Myrmotherula minor), Ihering's Antwren (Myrmotherula iheringi), Plain-winged Antwren (Myrmotherula behni), Ashy Antwren (Myrmotherula grisea), Unicolored Antwren (Myrmotherula unicolor), Alagoas Antwren (Myrmotherula snowi) and Rio de Janeiro Antwren (Myrmotherula fluminensis) as the "grey antwren assemblage", although this grouping possibly not monophyletic. Plumage and vocal differences suggest that some subspecies may be separate species and taxa in need of re-examination. Geographical ranges of subspecies tentative, based mainly on previously published statements.
