Subspecies
Close relationship to Slaty Antwren (Myrmotherula schisticolor) and Salvadori's Antwren (Myrmotherula minor) suggested by similarities in morphology, behaviour and vocalizations. Often grouped with those and White-flanked Antwren (Myrmotherula axillaris), Rio de Janeiro Antwren (Myrmotherula fluminensis), Rio Suno Antwren (Myrmotherula sunensis), 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.

The following 2 subspecies are recognised:

sunensis Chapman, 1925 - South-central Colombia (eastern slope of Andes in Meta and Putumayo) and Ecuador (Sucumbios, Napo, Pastaza); specimen from "mouth of R Curaray" (Peru) may have originated from Ecuador.
yessupi Bond, J, 1950 - East-central Peru (Hu�nuco, Pasco). Also south-western Amazonian Brazil (R Juru� but precise location uncertain, probably also R Javar��).
