On a new species of freshwater crab of the genus Johora (Brachyura, Potamidae) from Peninsular Thailand

Abstract

A new species of freshwater potamid crab of the genus Johora Bott, 1966, previously known only from Peninsular Malaysia and Singapore, is described from southern Thailand. The new species, J. thaiana, can be distinguished from congeners by its setose terminal segment of the male first pleopod, which is distinctly tapering and forming a conical structure, with the distal part slightly curved outwards. © Koninklijke Brill NV, 2005.
