Subspecies
Molecular-genetic data suggest that genus is most closely related to the "hooded" group of sierra-finches (Black-hooded Sierra-Finch (Phrygilus atriceps), Peruvian Sierra-Finch (Phrygilus punensis), Grey-hooded Sierra-Finch (Phrygilus gayi) and Patagonian Sierra-Finch (Phrygilus patagonicus)). Also, that it belongs within the tanager family (Thraupidae). Present species may form a superspecies with Patagonian Yellow-Finch (Sicalis lebruni) and were previously considered conspecific, but differs significantly in plumage, shape, structure and vocalizations.
The following 4 subspecies are recognised:
salvini (Chubb, C, 1919) - Northern Peru from La Libertad south to Huánuco.
chloris Cabanis, 1846 - Western and southern Peru (Ancash south to Tacna) and northern Chile (Arica-Parinacota south to Coquimbo).
olivascens (d'Orbigny & Lafresnaye, 1837) - South-eastern Peru (Cuzco and Puno) and western and central Bolivia south to north-western Argentina (Salta and Jujuy south to northern La Rioja).
mendozae (Sharpe, 1888) - Western Argentina from southern La Rioja south to Mendoza and San Luis. Considered by some authors to be a distinct species, Monte Yellow-Finch (Sicalis mendozae).
