Subspecies
Molecular data suggest that this genus is part of a clade which includes also Catamenia, as well as Plumbeous Sierra-Finch (Geospizopsis unicolor) and Ash-breasted Sierra-Finch (Geospizopsis plebejus) (but not others of that genus). In particular, a relationship between present genus and Plumbeous Sierra-Finch (Geospizopsis unicolor) was suggested by early authors on basis of similarities in plumage and structure. Molecular data indicate also that Acanthidops is related to present genus. This species probably forms a superspecies with Slaty Finch (Spodiornis rusticus).
