Subspecies
Recent molecular-genetic studies indicate that this genus and Nesospingus, Spindalis and Phaenicophilus form a monophyletic clade that is sister to several New World warbler (Parulidae) genera (including Dendroica, Basileuterus and Vermivora), and are not closely related to other genera of present family. More recent evidence suggests that Chlorospingus is closest to genus Arremonops in family Emberizidae. Central American subspecies of this species, hypophaeus, geographically isolated and differing from others in plumage, may prove to be a separate species. Further study is required.
The following 3 subspecies are recognised:
hypophaeus Sclater, PL & Salvin, 1868 - Western Panama from Volcán Barú (Volcán de Chiriquí) east to central Veraguas. Considered by some authors to be a distinct species, Orange-throated Bush-Tanager (Chlorospingus hypophaeus).
marginatus Chapman, 1914 - Western slope of western Andes in Colombia (from Valle del Cauca) south to south-western Ecuador (El Oro).
flavigularis (Sclater, 1852) - Andes of Colombia (northern end of western range in Córdoba and Antioquia, both slopes of central range in Antioquia, and eastern slope of eastern range southern from Boyacá) southern on eastern slope to Ecuador and Peru (south to Puno).
