Shane T. Ahyong, and Hsi-Te Shih (2017) A new genus and four new
species of freshwater crab, Cantopotamon zhuhaiense n. gen., n. sp., C.
shangchuanense n. gen., n. sp., C. hengqinense n. gen., n. sp. and C.
yangxiense n. gen., n. sp. are described from Guangdong, China, based
on morphology and two mitochondrial markers (16S rDNA and cytochrome
oxidase subunit I). Species of Cantopotamon closely resemble species of
Dai & Türkay, 1997, but differ by the combination of
carapace, third maxilliped, male pleon, male first gonopod and female
vulva characters. Molecular data derived from the mitochondrial 16S
rDNA also supports the establishment of the new genus.
