The great woolly horseshoe bat (Rhinolophus luctus) is a species of bat in the family Rhinolophidae. It is endemic to Southeast Asia. The northern woolly horseshoe bat (R. perniger), Malaysian woolly horseshoe bat (R. morio), and Andersen's woolly horseshoe bat (R. foetidus) were previously classified in this species but have since been reclassified as their own species, and other populations have been described as distinct species of their own: the Selangor woolly horseshoe bat (R. luctoides).

GBIF citizen-science records
It is estimated from how often the Woolly Horseshoe Bat is recorded against all the mammals logged in Cat Tien National Park (17 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.
