Sicyopterus rapa, new species of sicydiine goby (Teleostei: Gobiidae), from Rapa, French Polynesia

Abstract

Sicyopterus rapa, apparently endemic to one of the two southernmost islands of French Polynesia in the south central Pacific Ocean, is distinguished from congeners by a low number of premaxillary teeth and an unsealed ventral surface of the body in largest adults. Its putative closest living relatives are in the Marquesas and Indonesia.
