Records of Two Manefishes, Platyberyx andriashevi and P. rhyton (Teleostei: Perciformes: Caristiidae), from off the Ogasawara Islands, Japan

We examined four specimens of caristiids from the Ogasawara Islands, southern Japan, and identified two species of the genus Platyberyx: P. andriashevi (Kukuev, Parin and Trunov, 2012) and P. rhyton Stevenson and Kenaley, 2013. The three specimens of P. andriashevi represent the first records of this species in Japan. We propose a new Japanese name for the species and present morphological data on these recently collected specimens. Platyberyx rhyton was previously known from only two specimens from off northeastern Japan. We provide morphological data for the third recorded specimen of this species and present a key to the five species of Caristiidae currently known from Japan.
