First Shikoku and northernmost distributional records of Pseudoplesiops annae (Teleostei: Perciformes: Pseudochromidae)

Nine valid species known for the genus Pseudoplesiops (Pseudochromidae), and three of them have been recorded from Japanese waters. A single specimen of Pseudoplesiops annae (Weber, 1913), was currently collected from off Komame, Otsuki, Kochi Prefecture, southwestern Shikoku. This species can be distinguished from its congeners by its fin ray and scale counts, and lacking well developed intermandibular flap. This species has previously recorded only from Io-jima and Amami-oshima islands at Kagoshima Prefecture, and the former was the northernmost distributional record of the species. The present specimen represents the first record of the species from Shikoku, and the northernmost distributional record of the species.
