title: Binhthuanomon vinhtan, a new genus and new species of semi-terrestrial freshwater crab (Crustacea: Decapoda: Brachyura: Potamidae) from south central Vietnam.
abstract: A new genus and new species of semi-terrestrial crab of the family Potamidae, Binhthuanomon vinhtan n. sp., is described from south central Vietnam. The new genus is morphologically closest to Villopotamon Dang & Ho, 2003, and Balssipotamon Dang & Ho, 2008, in the shapes of the carapace and first gonopod but is easily distinguished by distinct carapace characteristics and gonopod 1 structures, and the habitat occupied.
