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.

Un nouveau crabe d’eau douce du genre Sinopotamon Bott, 1967, S. baokangense sp. nov. (Potamidae) provenant du district de Baokang, province du Hubei, Chine, est décrit. La nouvelle espèce ressemble fortement aux deux autres espèces chinoises: S. cochlearidigitum Dai, Chen, Zhang & Lin, 1986, district de Fang et Zhushan; et S. introdigitum Dai, Chen, Zhang & Lin, 1986, district de Fang, Yun et Shennongjia, dans leur morphologie générale et leur chélipède à l’extrémité caractéristique. La nouvelle espèce, cependant, peut facilement être distinguée par certains caractères du chélipède, de l’abdomen du mâle et du premier gonopode du mâle.
