Subspecies
Formerly treated as a subspecies of Short-crested Flycatcher (Myiarchus ferox), but the two differ in vocalizations and do not respond to playback of voice of each other. Similarly, species-level separation from Venezuelan Flycatcher (Myiarchus venezuelensis) argued on basis of sympatry in extreme north-western Venezuela (near Cerro Alto del Cedro) and in northern Colombia (Cansoma, in Bolívar). Analyses of morphological characters and mitochondrial DNA indicate close affinities with those two species and also with Sooty-crowned Flycatcher (Myiarchus phaeocephalus), but precise relationships within that group unclear.
The following 2 subspecies are recognised:
actiosus Ridgway, 1906 - Pacific coast of Costa Rica (Gulf of Nicoya south to point north of Osa Peninsula).
panamensis Lawrence, 1860 - Extreme south-western Costa Rica (Rincón de Osa, Puerto Jiménez), Panama (Caribbean slope in western Bocas del Toro and from northern Coclé east to San Blas, lowlands and foothills on Pacific coast, also Pearl Is, Coiba I, Taboga I and other smaller islands), northern and western Colombia (east to Guajira Peninsula, south to Tumaco, in south-western Nariño, lower Cauca Valley and upper Magdalena Valley at least to Neiva and Villavieja) and Maracaibo region of north-western Venezuela.
