Abstract: One male bat was collected in a cave in Cuibi Hill (N: 21°53', E: 101°18', H: 683 m a.s.l.), Menglun Town, Mengla County, Yunnan Province, in 26 November, 2006. This bat is a middle species with 60.7 mm forearm and 21.4 g body mass. The ears are large oval and joined medially to the forehead at about 15% of the height of inner margin. The tragus of each ear is well-developed and distinctly bifid. The noseleaf is simple. Posterior noseleaf is oval with obtuse tip and convex sides, a significant longitudinal ridge laying middle, which connects to intermediate noseleaf at the base. Intermediate noseleaf presents triangle with W-shape at the tip. Frontal noseleaf is horseshoe shape and attached directly to the muzzle. The tail is absent. The second finger of each wing has only one phalanx. There are no upper incisors, Pm³ and Pm₃. The upper canine has an anterior and a large posterior basal cusps. This bat is identified as lesser false vampire, Megaderma spasma, which is the new record of China. Its external and craniodental measurements were presented and compared with those of M. lyra. The specimen was preserved in Guangdong Entomological Institute.
