Subspecies
Atlapetes schistaceus (Sibley and Monroe 1990, 1993) has been split into Slaty Brush-Finch (Atlapetes schistaceus) and Cuzco Brush-finch (Atlapetes canigenis) following SACC (2005).
Until recently, generally treated as conspecific with Cuzco Brush-finch (Atlapetes canigenis). Sometimes thought to form a superspecies with Bay-crowned Brush-finch (Atlapetes seebohmi) and Rusty-bellied Brush-finch (Atlapetes nationi), and often considered conspecific with former. Has been suggested that this species and Vilcabamba Brush-finch (Atlapetes terborghi), Black-faced Brush-finch (Atlapetes melanolaemus) and Rufous-naped Brush-Finch (Atlapetes rufinucha) are related in a complex manner, with yellow coloration lost or gained in a leap-frog pattern, such that taxa which do not look alike may in fact be closely related to each other. Subspecies taczanowskii possibly represents a separate species. Further study needed.
The following 5 subspecies are recognised:
fumidus Wetmore & Phelps Jr, 1953 - Sierra de Perijá, on northern Colombia-western Venezuela border.
castaneifrons (Sclater, PL & Salvin, 1875) - Andes of Venezuela (Trujillo, Mérida and central and eastern Táchira).
tamae Cory, 1913 - Western Venezuela (south-western Táchira) and adjacent Colombia (Norte de Santander).
schistaceus (Boissonneau, 1840) - Western and central Colombian Andes (southern from Antioquia and Norte de Santander) and northern and central Ecuador.
taczanowskii (Sclater, PL & Salvin, 1875) - Andes of central Peru (Huánuco south to Junín). Considered by some authors to be a distinct species, Taczanowski's Brush-finch (Atlapetes taczanowskii).
