The glittering-bellied emerald (Chlorostilbon lucidus) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. The glittering-bellied emerald was widely called by the scientific name Chlorostilbon aureoventris, but in 2006 José Pacheco and Bret Whitney showed that lucidus is the correct specific epithet due to the principle of priority.
The Clements taxonomy and BirdLife International's Handbook of the Birds of the World add C. l. igneous, whose population the IOC includes in the nominate. Some ornithologists believe that pucherani is "approaching the species threshold".

GBIF citizen-science records
It is estimated from how often the Glittering-bellied Emerald is recorded against all the birds logged in Emas National Park (22 verified sightings from 2019 to 2026), 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.
