First distributional record of Neoniphon argenteus (Beryciformes, Holocentridae) from the Miyako Islands, Japan

A single specimen (137.2 mm standard length) of Neoniphon argenteus (Valenciennes, 1831) (Beryciformes: Holocentridae) was collected from Irabu-jima island in the Miyako Islands, Ryukyu Islands, Japan. In Japan, this species has previously been recorded only from Okinawa-jima island and the Yaeyama Islands. This specimen represents the first record of N. argenteus from the Miyako Islands, suggesting that this species is most likely to be widely distributed in the Ryukyu Islands.
