Abstract

The Western Ghats has been well studied for freshwater crabs among the regions of the Indian subcontinent. Several studies on the Western Ghats crabs notwithstanding, their actual diversity is still incompletely known. The previous data on their diversity seems to be erroneous. The freshwater crabs of the Western Ghats are revisited to update the information on their diversity, distribution, endemism, and conservation, which include 888 locality records from 46 publications. The updated data comprises 62 crab species in 18 genera of the family Gecarcinucidae, including recognition of two new records from the Western Ghats: Oziotelphusa biloba and Oziotelphusa ravi. The Western Ghats crabs contribute nearly half the diversity of the Indian freshwater crabs and more than two-thirds the diversity of the Indian gecarcinucid crabs. Nearly two-thirds crab species of the Western Ghats have been reported during the last two decades. The Southern Western Ghats is relatively rich in crab diversity as compared to the Northern- and Central Western Ghats.
