A new species of terrestrial freshwater sesarmine crab (Decapoda: Brachyura), Geosesarma krathing spec, nov., is described from near a waterfall in Chanthaburi Province, eastern Thailand. This is the first record of the genus from that part of Thailand. The species is allied to G. peraccae (Nobili, 1903) from Singapore and southern Peninsular Malaysia, but differs in the form of the carapace and male first pleopod structure.
