Abstract
Freshwater brachyuran crabs in the limestone caves of northern and western Thailand were studied. Overall, 65 caves in nine provinces were investigated. The crabs obtained were referred to six species of six genera in two families. A checklist and the distribution of freshwater cave-dwelling crabs in Thailand and Southeast Asia are also provided. In Thailand at least 16 species of 14 genera in two families are recognized. On a broader scale, a total of at least 70 cave-dwelling crab species of 36 genera in three families are recorded in Southeast Asia. The majority are in the family Gecarcinucidae (14 genera, 43 species), followed by the families Potamidae (19 genera, 24 species) and Hymenosomatidae (3 genera, 3 species). The troglofaunal status for each species is also given.
