A new species of freshwater crab of the genus Stoliczia Bott, 1966 (Crustacea: Brachyura: Potamidae) from the summit of Bukit Larut, Perak, Peninsular Malaysia

A new highland species of potamid freshwater crab of the genus Stoliczia Bott, 1966, is described from Bukit Larut, Perak, Peninsular Malaysia. Stoliczia larutensis, new species, is diagnosed by its ovate carapace with smooth dorsal surface, slender ambulatory legs and a characteristic male first gonopod structure. With regards to the first male gonopod, it is perhaps closest to S. leoi (Ng & Yang, 1985) described from mountains southeast of Bukit Larut. Stoliczia larutensis, however, differs markedly in a number of carapace, ambulatory leg and male abdominal characters.
