The present paper deals with the freshwater crab fauna of Sichuan Province based on the materials mainly collected by the Institute of Zoology, Academia Sinica since the 1960's. Some of them were taken from the Mt. Hengduan of Southwest mountainous area in 1981-1984. Materials collected by the Institute of Parasitology of Sichuan Province during the survey of Paragonimaisis have also been studied. A total of 257 numbers of specimens from 74 counties were examinined, and 25 species and subspecies belonging to 3 families and 5 genera were identified. Among them, 8 species and subspecies are considered to be new to science. All the type specimens are deposited in the Institute of Zoology, Academia Sinica.Discriptions of New Taxa Potamiscus elaphrius sp. nov. Dai et Chen (pl.
