Chionomesa Explained

Chionomesa is a genus of South American hummingbirds in the family Trochilidae.

Species

The genus contains two species:^[1]

These two species were formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic.^[2] In the revised classification to create monophyletic genera, these species were moved to the resurrected genus Chionomesa that had been introduced in 1921 by the French naturalist Eugène Simon.^{[1] [3] [4]} The genus name combines the Ancient Greek khiōn meaning "snow" with mesos meaning "middle".^[5] The type species was designated as the sapphire-spangled emerald by the American ornithologist Charles Wallace Richmond in 1927.^{[6] [7]}
