Abstract

The systematics of two problematic potamid species, Sinopotamon koatenense (Rathbun, 1904) and Sinopotamon wuyiensis Li, Lin, Cheng & Tang, 1985, both originally described from the Wuyi Mountains are resolved in this study. Sinopotamon koatenense is transferred to the genus Huananpotamon Dai & Ng, 1994, as the new combination Huananpotamon koatenensecomb. nov. The new combination differs from its congeners in the form of the carapace, male pleon, male first gonopod, and vulvae. Phylogenetic analyses based on mitochondrial 16S rDNA sequences support the identification of Huananpotamon koatenensecomb. nov. and a redescription is also provided. In addition, S. wuyiensis is confirmed as a junior synonym of Sinopotamon fukienense Dai & Chen, 1979 based on morphological similarities and phylogenetic lineages.
