Subspecies
No subspecies.
Molecular-genetic studies indicate that genus belongs in tanager family (Thraupidae). May form a superspecies with Peruvian Sierra-Finch (Phrygilus punensis), Grey-hooded Sierra-Finch (Phrygilus gayi) and Patagonian Sierra-Finch (Phrygilus patagonicus) (the "hooded" group), and molecular data suggest that this group may be closely related to Sicalis. Has been considered conspecific with Grey-hooded Sierra-Finch (Phrygilus gayi), but the two rarely hybridize in area of north-central Chile (between Atacama and Coquimbo) where they are sympatric (only one hybrid specimen known, from Guatín, in Antofagasta). Geographical variation minimal. Individuals from central Bolivia south to north-western Argentina slightly longer-billed than others, but difference likely clinal variation, also males from north-western Bolivian Altiplano (Sajama) said to be particularly black-winged.
