Subspecies
Most populations exhibit extraordinary individual variation (especially in colour of wingbars), even at a single locality, and majority of named subspecies cannot be distinguished from one another. Hence, hellmayri (Costa Rica and western Panama), transandinus (eastern Panama, western slope of western Andes of Colombia, western Ecuador), poliocephalus (central and eastern Andes of Colombia), venezuelensis (northern Venezuela, from western Zulia east to Monagas) and pariae (extreme north-eastern Venezuela in Sucre, and Trinidad) all merged with nominate. Transition to distinctive white-bellied subspecies albidiventer occurs sharply in eastern Andes of central Peru, and both plumage types occur together from Ayacucho south to Cuzco.
The following 3 subspecies are recognised:
superciliaris Tschudi, 1844 - Mountains of Costa Rica and Panama, Colombia (all three cordilleras), Venezuela (Andes and coastal mountains, and Paria Peninsula), Trinidad, Ecuador (both slopes) and eastern Peru (south to Ayacucho).
albidiventer Hellmayr, 1918 - Eastern Peruvian Andes (southern from Ayacucho and Cuzco) and northern Bolivia (La Paz, Cochabamba, western Santa Cruz). Considered by some authors to be a distinct species, White-bellied Flycatcher (Leptopogon albidiventer).
transandinus Berlepsch & Taczanowski, 1884 - Highlands of Costa Rica and Panama, and west slope of the Andes of Colombia and Ecuador.
