Abstract: Materials of the fossil primales were collected from two caves: Xiashan cave and Shanbeiyan cave, Luoding County, Guangdong province. Luoding County is locatedin Southwest Dayunwu mountain and is contiguous to Guangxi. The elements of fauna from Luoding has been reported (Huang et al. 1988;' Chen, 1988). In this paper we made the taxonomy of primate in detail. These fossil primates were assigned to three families: Pongidae, Hylobatidae and Cercopithecidae. The fossil pongo have been reported by Gu et al. (1987). 91 teeth are described in this paper. 60 of them are from Xiashan cave, other 31 teeth were collected from shanbeiyan. The gibbons are determined to Hylobates concolor and were collected from Xiashan cave. In Cercopithecidae there are Rhinopithecus sp., cf. Pygathrix nemaeus, cf. Trachypithecus phyrei, Trachypithecus sp., Trachypithecus francois, cf. Macaca assamensis, Macaca thibetana, Macaca mulatta and Macaca sp. These materials except T. francois, all appeared in two caves. T. francois was only found from Xiashan cave. In the Xiashan cave and the Shanbeiyan cave the assemblage of the fossil primates see the Chinese text.
