The pholcid spiders from Tibet, China, are reviewed. Seven species belonging to three genera are recorded. A new genus, Tibetia, is established, and four new species, Pholcus medog, P. zham, Belisana gyirong and B. mainling are described. And two new combinations are formed: Tibetia everesti (Hu & Li 1987) is transferred from Pholcus, and Belisana yadongensis (Hu 1985) is transferred from Spermophora.
