crabs of the Western Ghats have been severely underestimated in their
diversity. Since freshwater crabs have a small spatial scale endemism,
many remote and poorly studied localities in the Western Ghats need to
be surveyed. In this study, a new genus and new species is described.
Results: Arcithelphusa cochleariformis
gen. et sp. nov. is described from Ondayangadi, Wayanad district,
Kerala, India. The new genus and new species is exceptional among
Indian freshwater crabs due to its squarish, highly arched carapace,
appearing box-like in frontal view, and long, stout, spoon-shaped male
the current discovery, 14 genera and 36 species of gecarcinucid
freshwater crabs are recognized in the Western Ghats of India. More new
taxa can be expected from this exceptionally biodiversity-rich area if
the necessary surveys are done.
