Subspecies
A study of mitochondrial DNA has suggested that Crescent-chested Warbler (Oreothlypis superciliosa) and Flame-throated Warbler (Oreothlypis gutturalis) are close to Vermivora, and the two are often placed in latter genus. Other studies indicate that both genera as currently constituted are not monophyletic, and suggest that these two species should be placed in a separate genus, for which the name Oreothlypis is available. Subspecies sodalis of questionable validity, may be indistinguishable from mexicana.
The following 5 subspecies are recognised:
sodalis (Moore, RT, 1941) - North-western Mexico (Sierra Madre Occidental from south-eastern Sonora and southern Chihuahua south to northern Jalisco).
mexicana (Bonaparte, 1850) - Eastern Mexico (Sierra Madre Oriental from Nuevo León south to central Veracruz, thence west through Michoacán to eastern Jalisco).
palliata (van Rossem, 1939) - Southern Jalisco south to Guerrero, in southern Mexico.
superciliosa (Hartlaub, 1844) - Highlands of southern Mexico (Chiapas), Guatemala, El Salvador and western Honduras.
parva (Miller, W & Griscom, 1925) - Central and eastern Honduras and north-western Nicaragua.
