There are seven recognized subspecies of the Social Flycatcher. Myiozetetes simlis primulus resides in western Mexico from southern Sonoroa south to northern Sinaloa (del Hoyo et al. 2004). M. s. hesperis is found also in western Mexico (C Sinaloa and S Zacatecas E to SW Pubela, S at least to SE Oaxaca) (del Hoyo et al. 2004). M. s. texensis is found in eastern and southern Mexico from southwestern Tampaulipas south through Yucatan Pinsula. This subspecies is also found in Guatemala, Belize, El Salvador, Honduras, Nicaragua and Costa Rica (del Hoyo et al. 2004). It is thought that these three subepcies may actually form a different species (del Hoyo et al. 2004).
Myiozetetes similis columbianus is found in southwest Costa Rica and Panama, the northern coast of Colombia and in northern Venezuela (del Hoyo et al. 2004). M. s. grandis resides in western Ecuador, as well as in northwestern Peru (del Hoyo et al. 2004). M. s. similis occupies eastern Colombia, east of the Andes, southeastern Venezuela, French Guiana, eastern Ecuador, eastern and central Peru, Amazonian Brazil and Northern Bolivia (del Hoyo et al. 2004). The final recognized subspecies, M. s. pallidiventris is found in eastern Brazil, eastern Paraguay and northeast Argentina (del Hoyo et al. 2004).
