The posterior margin of the telson is rounded and ends a short median tooth. Thereare 3 pairs intermediate spines, which are shorter than the lateral spines. Carpus of the 1st leg is 1.4-1.5 times as long as wide, and the chela is 1.8-2.0times as long as wide. Carpus of the 2nd leg is 4.9-5.0 times as long as wide, and thechela is 2.4-2.5 times as long as wide. Endopod of the 1st male pleopod is leaf-shaped.
