Subspecies
White-naped Brush-finch (Atlapetes albinucha) and Yellow-throated Brush-Finch (Atlapetes gutturalis) (Sibley and Monroe 1990, 1993) have been lumped into Atlapetes albinucha following SACC (2005).
Often placed in genus Buarremon or Arremon. Subspecies form two groups, the "albinucha group" (nominate and griseipectus) and "gutturalis group" (remaining races). These often treated as two separate species, but differences between them appear to be insufficient to justify such treatment. Subspecies fuscipygius appears to intergrade with griseipectus in north-western El Salvador. Poorly differentiated subspecies coloratus possibly better merged with brunnescens.
The following 8 subspecies are recognised:
albinucha (Lafresnaye & D'Orbigny, 1838) - Caribbean slope of Mexico from Puebla and Veracruz south to Oaxaca and Chiapas.
griseipectus Dwight & Griscom, 1921 - Pacific slope of south-western Chiapas (southern Mexico), highlands of western Guatemala and El Salvador (San José del Sacre and Volcán de Santa Ana).
fuscipygius Dwight & Griscom, 1921 - Highlands of Honduras, north-western El Salvador (Los Esesmiles) and north-western Nicaragua.
parvirostris Dwight & Griscom, 1921 - Subtropical zone of Costa Rica.
brunnescens Chapman, 1915 - Subtropical zone of western Panama (western Chiriquí).
coloratus Griscom, 1924 - Subtropical zone of eastern Chiriquí (Panama).
azuerensis Aldrich, 1937 - Azuero Peninsula, in southern Panama.
gutturalis (Lafresnaye, 1843) - Upper tropical and subtropical zones of Colombian Andes southern from Antioquia, Santander and Norte de Santander. Considered by some authors to be a distinct species, Yellow-throated Brush-Finch (Atlapetes gutturalis).
