Subspecies
Relationships uncertain. Often placed with the Western Stipple-throated Antwren (Epinecrophylla haematonota) group (the "stipple-throated antwren assemblage") because of its dotted throat, but that placement is put in question by the finding of a cup rather than globular nest. Also, its behaviour suggests that it may be related to Rufous-bellied Antwren (Isleria guttata) and Plain-throated Antwren (Isleria hauxwelli). Its vocalizations appear to be intermediate.
