摘要：

A new genus new species of freshwater crab and a new Minpotamon Dai & Turkay, 1997 species are described from eastern Guangdong, China, based on morphology and mitochondrial 16S rDNA sequences. The new genus, Teoswamon gen. nov., is established for T. scolasticum sp. nov., which resembles species from several other genera from Guangdong, but its unique combination of carapace, male gonopod and female vulvae characters set it apart from others. Minpotamon kityang sp. nov. is almost identical with Minpotamon nasicum (Dai. Chen. Song, Fan. Lin & Zeng, 1979) externally, but differs drastically in the male gonopod morphology. Molecular analysis supports the current taxonomic treatments. Teoswamon scolastictun sp. nov. forms its own lineage closely related to Huananpotamon Dai & Ng, 1994. Minpotamon kityang sp. nov. clusters with Minpotamon nasicum, but their genetic distance is of an interspecific level.
