This species was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the glittering-throated emerald and the sapphire-spangled emerald (Chionomesa lactea) were moved by most taxonomic systems to the resurrected genus Chionomesa that had...
