Subspecies
Sometimes placed in a separate genus, Melodivireo. May form a superspecies with Eastern Warbling-Vireo (Vireo gilvus), and often considered conspecific, but the two differ in plumage and some vocalizations. Northern subspecies (eleanorae, dubius, amauronotus, strenuus, bulli, palmeri) have been treated as forming a separate species, distinct from that consisting of remaining subspecies (in Costa Rica, Panama and South America).
Proposed subspecies chiriquensis (described from Boquete, at Volcán de Chiriquí, in Panama) and disjunctus (from Antioquia, in Colombia) both treated as synonyms of dissors.
The following 14 subspecies are recognised:
eleanorae Sutton & Burleigh, 1940 - North-eastern Mexico (south-western Tamaulipas south to northern Hidalgo).
dubius (Phillips, AR, 1991) - East-central Mexico (near Ciudad Victoria, in Tamaulipas).
amauronotus Salvin & Godman, 1881 - South-eastern Mexico (north-eastern Puebla east to west-central Veracruz).
palmeri (Phillips, AR, 1991) - Mountains of Honduras, possibly also northern El Salvador.
costaricensis (Ridgway, 1903) - Central Costa Rica (Cordillera de Tilarán).
dissors Zimmer, JT, 1941 - Southern Costa Rica, western and eastern Panama, and north-western Colombia (western and central Andes, southern on western slope to western Nariño).
mirandae Hartert, 1917 - Northern Colombia (Santa Marta Mts) and north-western Venezuela (Zulia, and Táchira east to Sucre).
josephae Sclater, PL, 1859 - South-western Colombia (central Andes in Nariño) and western Ecuador.
leucophrys (Lafresnaye, 1844) - Eastern Andes from Colombia south to central Peru.
maranonicus Zimmer, JT, 1941 - Northern Peru (both slopes of western Andes, west of R Marañón).
laetissimus (Todd, 1924) - South-eastern Peru and northern Bolivia (La Paz and Cochabamba).
chiriquensis (Bangs, 1903) - Subtropical Costa Rica and extreme western Panama.
