Abstract

The porcellanid crab, Polyonyx boucheti, previously known only from the Loyalty Islands in the south-western Pacific, is reported from the south-western Indian Ocean based on two specimens collected from Mayotte, Comoro Islands. The present material agrees well with the original description of the species in every diagnostic aspect. Polyonyx boucheti is widely distributed in the Indo-West Pacific as is its closest congener P. utinomii, although the records of the two species are very limited.
