Abstract

A new potamiscine genus, Laevimon, is established for two species of semi-terrestrial freshwater crabs from Vietnam, viz., Laevimon kottelati, new species (type species) and L. tankiensis (Dang & Tran, 1992). The genus is morphologically closest to Hainanpotamon Dai, 1995, but is easily distinguished by distinct sternal and gonopodal characters. The status of Orientalia Dang, 1975, a synonym of Hainanpotamon, as a junior homonym of Orientalia Radoman, 1972 (Mollusca), is also discussed.
