AbstractThe little yellow-shouldered Mesoamerican bat, Sturnira parvidens Goldman, 1917, is a medium-sized yellow-shouldered bat with no tail, a vestigial uropatagium, and reddish or yellowish patches on the shoulders. It lives in tropical habitats associated with lower and mid-elevations from northern Costa Rica to Mexico, and it is one of 24 described species in the genus Sturnira. Although S. parvidens is more common in disturbed areas because it mainly feeds on pioneer plants, it uses day roosts located in mature forest or in areas with advanced successional stages. It is an abundant species and is listed as “Least Concern” by the International Union for Conservation of Nature and Natural Resources.
