Subspecies
Geographical variation largely clinal, e.g. colour of underparts gradually changing from dark red in north to yellow in South America and amount of black on face decreasing from north to south. Recently suggested by some authors that ballux and subsimillis be synonymized with verticalis.
The following 12 subspecies are recognised:
miniatus (Swainson, 1827) - Mexico from southern Sonora, south-western Chihuahua and San Luis Potosí south to southern Oaxaca.
molochinus Wetmore, 1942 - Sierra de Tuxtla, in south-eastern Veracruz (eastern Mexico).
