A new species of freshwater crab of the genus Tiwaripotamon Bott, 1970 (Crustacea, Brachyura, Potamidae) from northern Vietnam and southern China.

A new freshwater crab species of the family Potamidae is described from the boundaries of northern Vietnam and southern China. Tiwaripotamon pluviosum sp. nov. can be distinguished from other species by a suite of morphological characters, including a relatively flat carapace, relatively less slender legs, and distinct dorsal flaps on the male first gonopods. Molecular data using the mitochondrial cytochrome oxidase subunit I (COI) also supports this species as being new.
