[New record of a bat species from China, Megaderma spasma (Linnaeus, 1758)].

One male bat was collected in a cave in Cuibi Hill (N: 21 degree 53', E: 101 degree 18', H: 683 m a.s.l.), Menglun Town, Mengla County, Yunnan Province, on November 26, 2006. This bat is of medium body size, with 60.7 mm forearm and 21.4 g body mass. Its ears are large ovals and joined medially to the forehead at about 15% of the height of inner margin. The tragus of each ear is slender and distinctly bifid. The noseleaf is simple, and the 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 a W-shaped tip. Frontal noseleaf is horseshoe shape and attached directly to the muzzle. The tail is absent, and 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 a new record of China. Its external and craniodental measurements were presented and compared with those of M. lyra. The specimen is preserved in Guangdong Entomological Institute.
