An annotated checklist of the marine fishes of the Uji Islands in the East China Sea, Kagoshima Prefecture, southern Japan, was compiled on the basis of 560 specimens from field and literature surveys. All registered specimens previously recorded from the Uji Islands in published papers were re-examined. A total of 153 species (126 genera and 70 families) plus one hybrid individual of the Oplegnathidae, including 148 species that represent the first records from the islands on the basis of collected specimens, are listed with citations of literature, registration numbers, sizes, nomenclatural and taxonomic remarks, and color photographs if available. The zoogeographical implications of the Uji Islands ichthyofauna are discussed. Vol. 64, pp. 10 ~ 34 (2015) Introduction The Uji Islands, a group of six uninhabited islands, is located at the northwestern extremity of the Ryukyu Islands (31°11ʹN, 129°27ʹE), north of the Okinawa Trough and west of the East China Sea continental shelf. It is also ca. 65 km west of the western coast of the Satsuma Peninsula (Kagoshima mainland) between Koshiki and Kusagaki islands (Fig. 1). The Uji Islands have a combined area of ca. 1.7 km and a highest point above sea level of 319 m. The islands are surrounded mostly by rocky reefs with small patchy coral reefs; there are no sandy beaches nor freshwater rivers around or on the islands. Fishes occurring on the East China Sea continental shelf and in the Okinawa Trough have been well surveyed and their species lists were published by Yamada et al. and Shinohara et al. 2) respectively. Recently, fishes of islands in the Osumi Group, including Yaku-shima, Iou-jima, and Take-shima islands, were comprehensively investigated and field guides 4) were published. Fukui et al. recorded 23 species from deepwater off Kuro-shima island in the Osumi Group. Although the fish faunas of such islands nearby the Uji Islands have been relatively well surveyed, only four papers recording fish species of the Uji Islands have been published (on the basis of specimens deposited at the Kagoshima University Museum): viz., Shimada, Yamashita et al., Hata et al., and Jeong et al.. This paper provides a list of 153 species of marine fishes (126 genera and 70 families), plus one hybrid individual of the Oplegnathidae, occurring off the Uji Islands on the basis of 560 collected specimens. Previously reported specimens from the islands were re-identified during this study. The zoogeographical implications of the Uji Islands ichthyofauna are discussed. 1 The Kagoshima University Museum, 1-21-30 Korimoto, Kagoshima 890-0065, Japan 2 Faculty of Fisheries, Kagoshima University, 4-50-20 Shimoarata, Kagoshima 890-0056, Japan 3 School & Diving Service Umikobo, 4-30-5 Shimoarata, Kagoshima 890-0056, Japan 4 The United Graduate School of Agricultural Sciences, Kagoshima University, 1-21-24 Korimoto, Kagoshima 890-0065, Japan 5 Fisheries Research Laboratory, Mie University, 4190-172 Wagu, Shima, Mie 517-0703, Japan 6 The Graduate School of Fisheries, Kagoshima University, 4-50-20 Shimoarata, Kagoshima 890-0056, Japan 7 Kanagawa Prefectural Museum of Natural History, 499 Iryuda, Odawara, Kanagawa 250-0031, Japan 8 National Museum of Nature and Science, 4-1-4 Amakubo, Tsukuba, Ibaraki 305-0005, Japan *Corresponding author, E-mail: motomura@kaum.kagoshima-u.ac.jp 11 Ichthyofauna of the Uji Islands Materials and Methods In this paper, fishes collected from waters within a 20-kilometer radius of the Uji Islands are listed; some fishes collected from outside the Uji area, such as 50 km off the Uji Islands, were listed by Fukui et al. as “fishes off Kuro-shima island”. Most specimens were collected by scuba diving and line-fishing during the RV Nansei-maru voyage on 21–23 April 2015 (Fig. 2), by free diving during a fishing boat expedition on 20–21 July 2013, and by purchasing fishes from the Uji Islands that were landed at the Kagoshima Central Fish Market. Additionally, some old specimens (possibly collected in the 1950’s) were found in the collection of the Faculty of Fisheries, Kagoshima University. Curatorial procedures for newly collected specimens followed Motomura and Ishikawa. The systematic arrangement of families follows Nelson. Scientific names generally follow Nakabo and Eschmeyer, with some modifications by recently published or unpublished taxonomic studies. Species in families are arranged in alphabetical order by species name. Standard Japanese names (abbreviated as ‘Jpn name’) follow Nakabo, and are transliterated using the Hepburn system. Each species record was compiled from voucher specimens and literature sources. Data for each voucher specimen comprises registration number and standard length [SL; sometimes total length (TL) or disc width (DW)]. Distributional and other remarks are included for some species. The list of specimens is followed by literature cited. Specimens collected from the Uji Islands have been deposited at collections of the Kagoshima University Museum, Kagoshima, Japan (KAUM), and the Kanagawa Prefectural Museum of Natural History, Odawara, Japan (KPM).
