Subspecies
May be closely related to Large Elaenia (Elaenia spectabilis) and formerly treated as conspecific, but ranges overlap widely in Brazil, and they have different voices. Birds in south-western Colombia appear intermediate between nominate subspecies and semipagana.
The following 4 subspecies are recognised:
subpagana Sclater, PL, 1860 - South-eastern Mexico east from southern Veracruz and Chiapas (including Mujeres I, off northern Quintana Roo) south to Costa Rica, also south-western Panama (Coiba I).
pallididorsalis Aldrich, 1937 - Panama and adjacent islands (except Coiba I).
flavogaster (Thunberg, 1822) - Colombia, Venezuela (including Margarita I and Patos I), Trinidad, Tobago, southern Lesser Antilles (the Grenadines, Grenada), the Guianan Shield, Brazil (southern, except in western and central Amazonas, to Rio Grande do Sul), south-eastern Peru, Bolivia, Paraguay and north-eastern Argentina.
semipagana Sclater, PL, 1862 - Extreme south-western Colombia, western and southern Ecuador (including Puná I) and interior north-western Peru.
