Separacion del ermitaño mexicano del ermitaño colalarga-suplemento 56 AOU (AUK vol 132 2015)

Phaethornis mexicanus is treated as a species separate from P. longirostris. In the species account for P. longirostris, change the distributional statement and Notes to: Distribution.—Resident [longirostris group] on the Gulf-Caribbean slope from Veracruz, Tabasco, northern Oaxaca, and northern Chiapas south through Central America to Nicaragua, on both slopes of Costa Rica and Panama, and in northern Colombia and northwestern Venezuela; and [baroni group] in South America west of the Andes in western Ecuador and northwestern Peru. Notes.—Groups: P. longirostris and P. baroni Hartert, 1897 [Hartert’s Hermit]. Formerly considered conspecific with extralimital P. superciliosus (Linnaeus, 1766) [Longtailed Hermit], but separated (Banks et al. 2002) largely on morphological grounds. See Notes under P. mexicanus.
Before the species account for P. longirostris, insert the following new account:
Phaethornis mexicanus Hartert. Mexican Hermit.
Phaethornis mexicanus Hartert, 1897, Ibis, p. 425. (Dos Arroyos, near Chilpancingo, Guerrero.)
Habitat.—Tropical Lowland Evergreen Forest, Montane Evergreen Forest (100–1,900 m; Tropical and Subtropical zones). Distribution.—Resident [griseoventer group] in western Mexico from west-central Nayarit (near Tepic and San Blas) south to Jalisco (Sierra de Autla ´n, Mineral San Sebastian) and Colima (Cerro Grande); and [mexicanus group] in Guerrero and western Oaxaca. Notes.—Groups: P. griseoventer Phillips, 1962 [Jalisco Hermit] and P. mexicanus. Formerly considered conspecific with P. longirostris, but treated as a separate species on the basis of differences in vocalizations, behavior, genetics, and morphology (Arbela ´ez-Cort´es and Navarro-Sig¨uenza 2013, Howell 2013, McGuire et al. 2014).
