Subspecies
No subspecies.
Forms a superspecies with other members of genus, as a series of non-overlapping mountain-top replacements, and all sometimes considered conspecific. Their vocalizations seem fairly close, but plumage patterns differ to an extent not found within individual species-level taxa in Furnariidae. Almost certainly paraphyletic with regard to White-chinned Thistletail (Asthenes fuliginosa) (which brackets its distribution to northern and south). Probably closest to latter's nominate subspecies, sharing with it the feature of a white eyering.
