Abstract: The Sciuridae from Shihuiba, a late Miocene hominoid locality at Lufeng, Yunnan Province are described. The fauna contains seven species of Sciuridae, including one new genus and four new species. One of the sciurids is a ground squirrel: Sciurotamias wangi sp. nov.; three are tree squirrels: Tamiops sp., Callosciurus sp. and Dremomys primitivus sp. nov.; and three are flying squirrels: Miopetaurista asiatica sp. nov., Hylopetodon dianense gen. et sp. nov. and Pteromyinae gen. et sp. indet. The sciurid fauna is characterized by its dominance of tree and flying squirrels, and reflects a rather humid and forsted environment. Biogeographically, the fauna is endemic to southeastern Asia, and is obviously Oriental in character.
