Vadosiapus copacabanus, n. gen. is described from the surf zone on the beach at Copacabana, Rio de Janeiro, Brazil. The genus and unique species is related to the three known species of Bathyporeiapus, which range southward from Brazil through the Magellan region of South America. Vadosiapus is distinguished from Bathyporeiapus in the odd phoxocephalid-like article 3 of the mandibular palp, the nonsinuate epimeron 2, the broadened tel son bearing only midsagittal armaments and the enlarged dactyl of gnathopod 2.
