Sinopotamon baokangense sp. nov., a new freshwater crab with spoon-tipped cheliped fingers from Hubei Province, P.R. China (Decapoda, Brachyura, Potamidae)

A new freshwater crab of the genus Sinopotamon Bott, 1967, S. baokangense sp. nov. (Potamidae), is described from Baokang County, Hubei Province, P.R. China. The new species closely resembles two other Chinese species: S. cochlearidigitum Dai, Chen, Zhang & Lin, 1986, from Fang and Zhushan Counties; and S. introdigitum Dai, Chen, Zhang & Lin, 1986, from Fang and Yun Counties and Shennongjia, in general morphology and their distinctive spoon-tipped cheliped fingers. The new species, however, can easily be distinguished by a number of cheliped, male abdominal, and male first gonopod characters.
