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...

GBIF citizen-science records
It is estimated from how often the Glittering-throated Emerald is recorded against all the birds logged in Rio de Janeiro (170 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
