Fishes of Yaku-shima island : a world heritage island in the Osumi group, Kagoshima prefecture, southern Japan

edited by Hiroyuki Motomura and Keiichi Matsuuraabstract for "First records of a triplefin (Tripterygiidae), Enneapterygius hemimelas, from Japan": Four male specimens (19.4–21.8 mm standard length) of Enneapterygius hemimelas (Kner and Steindachner, 1867) (Tripterygiidae) were collected from Yaku-shima Island, Kagoshima Prefecture, Kyushu, Japan. Because previous Japanese records of E. hemimelas were based on mis-identifications of E. bahasa or E. flavoccipitis, and the northernmost record of E. hemimelas was Taiwan, the Yaku-shima Island specimens examined in this study represent the first records of E. hemimelas from Japan and the northernmost record for the species.abstract for "New records of a triplefin, Enneapterygius leucopunctatus, from southern Japan (Perciformes: Tripterygiidae)": Enneapterygius leucopunctatus Shen, 1994 (Tripterygiidae), known only from Taiwan, is recorded for the first time from Yaku-shima Island, Kagoshima Prefecture, and Tosa Bay, Kochi Prefecture, southern Japan. Seventeen Japanese specimens (25.2–36.1 mm in standard length) were identified as E. leucopunctatus based on the following combination of characters: second dorsalfin spines 12–13; third dorsal-fin soft rays 9–11; anal-fin soft rays 17–19; mandibular pore formula mostly 4+1+4; pored and notched lateral-line scales 15–18+16–19; simple dermal flap of anterior nostril; 2 white oblique bands on shoulder girdle; 8 dark saddle markings and 5–6 small ring-like white markings on lateral body; inconspicuous sexual dichromatism.abstract for "Distributional range extension of a scorpionfish, Scorpaenodes quadrispinosus, in the Indo–Pacific, and comments on synonymy of S. parvipinnis (Scorpaeniformes: Scorpaenidae)": Scorpaenodes quadrispinosus, previously known only from type specimens from Fiji and the Marshall Islands, is reported here on the basis of 27 specimens from the eastern Indian Ocean (Christmas Island, Australia) and the Pacific Ocean (East Asia, Micronesia, Melanesia, Timor Sea, and Polynesia). Validity of diagnostic characters of S. quadrispinosus given in the original description is assessed and newly recognized diagnoses are provided. Paronescodes asperrimus is regarded here as a junior synonym of S. parvipinnis.abstract for "Apogonid fishes (Teleostei: Perciformes) of Yaku-shima Island, Kagoshima Prefecture, southern Japan": Forty five species of apogonid fishes were confirmed to occur at Yaku-shima Island, Kagoshima Prefecture, Kyushu, southern Japan. Of these, 27 species represent the first records from the island, including the first Japanese record of Apogon chrysotaenia. A new Japanese name, Akafujitenjikudai, is proposed for Apogon crassiceps. Each species account provides a synonym list, material examined, descriptions based on collected specimens, distribution in Japanese waters, taxonomic and nomenclatural remarks, and ecological notes from Yaku-shima Island.abstract for "Annotated checklist of marine and estuarine fishes of Yaku-shima Island, Kagoshima, southern Japan": An annotated checklist of marine and estuarine fishes of Yaku-shima Island, Kagoshima Prefecture, southern Japan, was compiled from field and literature surveys. All registered specimens previously recorded from Yaku-shima Island in published papers were re-examined. A total of 951 species (382 genera, 112 families, 24 orders), including 374 species that represent the first reliable records from the island on the basis of collected specimens, are listed with citation of literature, registration numbers, sizes, localities in the island, nomenclatural and taxonomic remarks, and color photographs if available. A new Japanese name is proposed for a bythitid, Alionematichthys piger. Zoogeographical implications of the Yaku-shima Island ichthyofauna are discussed.abstract for "Freshwater fishes of Yaku-shima Island, Kagoshima Prefecture, southern Japan": An annotated checklist of freshwater fishes of Yaku-shima Island, Kagoshima Prefecture, southern Japan, was compiled from field and literature surveys. A total of 32 species (22 genera, 11 families, 7 orders) are listed with citation of literature, registration numbers, sizes, localities in the island, ecological notes, and color photographs if available.covertitle page, colophonprefaceeditorscontents[p1-8] First records of a triplefin (Tripterygiidae), Enneapterygius hemimelas, from Japan / Masatoshi Meguro and Hiroyuki Motomura[p9-16] New records of a triplefin, Enneapterygius leucopunctatus, from southern Japan (Perciformes: Tripterygiidae) / Hiromitsu Endo, Eri Katayama, Mina Miyake and Kimi Watase[p17-26] Distributional range extension of a scorpionfish, Scorpaenodes quadrispinosus, in the Indo–Pacific, and comments on synonymy of S. parvipinnis (Scorpaeniformes: Scorpaenidae) / Hiroyuki Motomura, Gota Ogihara and Kiyoshi Hagiwara[p27-64] Apogonid fishes (Teleostei: Perciformes) of Yaku-shima Island, Kagoshima Prefecture, southern Japan / Tomohiro Yoshida, Shigeru Harazaki and Hiroyuki Motomura[p65-248] Annotated checklist of marine and estuarine fishes of Yaku-shima Island, Kagoshima, southern Japan / Hiroyuki Motomura, Kaoru Kuriiwa, Eri Katayama, Hiroshi Senou, Gota Ogihara, Masatoshi Meguro, Mizuki Matsunuma, Yohko Takata, Tomohiro Yoshida, Masahiro Yamashita, Seishi Kimura, Hiromitsu Endo, Atsunobu Murase, Yukio Iwatsuki, You Sakurai, Shigeru Harazaki, Kouichi Hidaka, Hikaru Izumi, and Keiichi Matsuura[p249-261] Freshwater fishes of Yaku-shima Island, Kagoshima Prefecture, southern Japan / Toshihiko Yonezawa, Akihiko Shinomiya and Hiroyuki Motomuraphoto
