Subspecies
Close relationship to Slaty Antwren (Myrmotherula schisticolor) and Rio Suno Antwren (Myrmotherula sunensis) suggested by similarities in morphology, behaviour and vocalizations. Often grouped with those and White-flanked Antwren (Myrmotherula axillaris), Rio de Janeiro Antwren (Myrmotherula fluminensis), Ihering's Antwren (Myrmotherula iheringi), Plain-winged Antwren (Myrmotherula behni), Ashy Antwren (Myrmotherula grisea), Unicolored Antwren (Myrmotherula unicolor), Alagoas Antwren (Myrmotherula snowi), Long-winged Antwren (Myrmotherula longipennis), Band-tailed Antwren (Myrmotherula urosticta) and Grey Antwren (Myrmotherula menetriesii) as the "grey antwren assemblage", although this grouping possibly not monophyletic. Specimens from south-western Amazonia tentatively assigned to this species by earlier authors, but identity of these requires substantiation, including further field studies and vocal and molecular analysis; may represent a distinct species.

No subspecies.

Similar Species
No other Myrmotherula has barred undertail-coverts. Male luctuosa of White-flanked Antwren (Myrmotherula axillaris) has silvery-grey flanks and more extensive black bib, female has contrastingly paler flanks. Both sexes of Band-tailed Antwren (Myrmotherula urosticta) have broad, white tail tip.
