The purple-naped spiderhunter or purple-naped sunbird (Kurochkinegramma hypogrammicum) is a species of bird in the family Nectariniidae. It is the only species in the genus Kurochkinegramma. It is found in Southeast Asia from Myanmar to Sumatra and Borneo. Its natural habitat is subtropical or tropical moist lowland forests.
A study published in 2011 appeared to show that the purple-naped spiderhunter was phylogenetically nested within the genus Arachnothera. A subsequent 2017 study, conducted by some of the same authors and using additional sequence data, found that the purple-naped spiderhunter occupied a basal position to Arachnothera. It was formerly placed in the genus Hypogramma until it was realised that the name was preoccupied within Lepidoptera.

GBIF citizen-science records
It is estimated from how often the Purple-naped Spiderhunter is recorded against all the birds logged in Cuc Phuong National Park (26 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.
