Yucatan Flycatcher (Myiarchus yucatanensis) - HBW 9, p. 431
French: Tyran du Yucatan
Spanish: Copetón Yucateco
Taxonomy: Myiarchus yucatanensis Lawrence, 1871, Yucatán, Mexico.
Has in the past been suggested as being conspecific with M. stolidus, but differs significantly in morphological and vocal characters. Phylogenetic analysis of mitochondrial DNA placed it in a clade with M. crinitus, M. cinerascens and M. tyrannulus. Geographical variation, including populations on Cozumel I (lanyoni), seems ecophenotypic (correlated with rainfall and vegetation); nominate race and navai apparently intergrade in C Yucatán Peninsula; sampling needed in order to test validity of existing taxonomy. Three subspecies currently recognized.
Subspecies and Distribution:
- yucatanensis Lawrence, 1871 - E Mexico, in extreme E Tabasco (near Balancán) and N & C Yucatán Peninsula.
- lanyoni Parkes & A. R. Phillips, 1967 - Cozumel I, off NE Quintana Roo (Mexico).
- navai Parkes, 1982 - S Quintana Roo (La Vega, Chetumal) and SE Campeche (Xpujil), in Mexico, and Guatemala (Tikal, in N Petén); probably also N Belize (Gallon Jug).
