Geographic Variation

Four subspecies recognized:

diluta van Rossem 1938; type locality Santiago, Nayarit, Mexico

Occurs in northwestern Mexico in Sinaloa and Nayarit. Perhaps not valid, as it intergrades with nominate rutila (Weller 1999).

Similar to nominate rutila, but "coloration below paler and more pinkish (less reddish) cinnamon, and upper parts slightly more golden (less greenish) bronze" (van Rossem 1938: 227).

rutila (DeLattre 1842); type locality Acapulco Guerrero, Mexico

Occurs from western and southern Mexico from Jalisco and Yucatán south to Honduras and northwestern Costa Rica.

See Detailed Description.

corallirostris (Bourcier and Mulsant 1846); type locality Escuintla, Guatemala

Occurs on the Pacific slope in Chiapas Mexico, south to the Lempa River, El Salvador; or includes the populations from the Yucatán south to Costa Rica, usually attributed to nominate rutila (Weller 1999).

Similar to nominate rutila, "but much more deeply colored, the under parts deep cinnamon-rufous, the tail chestnut, and green or bronze of back, etc., deeper and brighter" (Ridgway 1911).

graysoni Lawrence 1866; type locality Tres Marias Islands, Mexico

Restricted to Maria Madre Island, Tres Marias Islands, off the west coast of Mexico.

Similar to nominate rutila, "but darker, throughout, and much larger" (Ridgway 1911).

Related Species

Subspecies graysoni of the Tres Marias Islands formerly was recognized as a separate species (e.g. Ridgway 1911).

There is no phylogenetic survey of the large genus Amazilia. Weller (1999) considered rutila to form a superspecies with Amazilia yucatanensis (Buff-bellied Hummingbird).

Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, indicates that Amazilia is polyphyletic, as the genera Hylocharis, Chrysuronia, Lepidopyga, and Damophila are embedded within the current Amazilia (McGuire et al. 2007, 2008). The type species of the genus Amazilia is rutila, however, so although the nomenclature of Amazilia is destined for revision, the scientific name of Amazilia rutila will not change.
