Porcellanid crabs from Goa, Eastern Arabian Sea (Crustacea: Decapoda: Porcellanidae)

Abstract

We report here 10 species of Porcellanidae sampled along the coast of Goa, India, each of which is described and figured. Polyonyx splendidus is registered for the first time outside the type region, and Petrolisthes coccineus is registered for the first time for the Arabian Sea. Accordingly, the porcellanid fauna of the western coast of the Indian subcontinent now consists of 16 species, including two endemics, Polyonyx hendersoni and P. splendidus. For the Indian Ocean, 9 species are here reported as endemic. We provide a key for the identification of all species so far reported for the western coast of the Indian subcontinent.
