Ostorhinchus fleurieu Lacepede, 1802 is recorded from Japan for the first time on the basis of 21 specimens (37.6-106.8mm standard length) collected from Kagoshima Prefecture, southern Japan. On the basis of underwater photographs, Osezaki, Izu Peninsula, is regarded as the northernmost record of the species. The new Japanese name "Kongo-tenjikudai" is proposed for the species. Comparisons of Ostorhinchus fleurieu with closely related species, O. aureus, based on 21 and 12 specimens, respectively, from Japan showed that O. fleurieu differed from O. aureus in having fewer total gill rakers (19-21, mode 21 vs. 23-24, 24 in the latter) and developed gill rakers (16-18, 18 vs. 18-21, 20), the pelvic-fin base located below the first lateral-line scale (vs. second scale), and a poorly defined, barrel-shaped black band on the caudal peduncle (vs. well-defined, sandglass-shaped band).

The carangid genus Decapterus Bleeker, 1851 is characterized by single finlets behind both the second dorsal and anal fins, no scutes along the anterior curved part of the lateral line, two low papillae on the shoulder girdle, and a well-developed adipose eyelid. Members of the genus are distributed in tropical to temperate areas of the Pacific, Indian and Atlantic oceans, and are commercially important food fishes. Four species (D. akaadsi Abe, 1958, D. kurroides Bleeker, 1855, D. smithvanizi Kimura, Katahira and Kuriiwa, 2013 and D. tabl Berry, 1968), characterized by a red caudal fin, are included in the red-fin Decapterus group. In 2016 and 2018, three specimens [216–304 mm in standard length (SL)] of D. kurroides, previously recorded from the Red Sea and east coast of Africa to the east coast of Australia and the Philippines, were collected from Kumano-nada, Pacific coast of Mie Prefecture, Japan. Additionally, a single specimen (191 mm SL) collected from Japanese waters in the East China Sea (west of Kyushu) in 2006 was also identified as D. kurroides. The specimens represent the first records of the species from Japanese waters, the Kumano-nada specimens being the northernmost record for the species. Decapterus kurroides is the most similar to D. akaadsi, but differs from the latter in the following characters: scutes more numerous on the straight part of the lateral line (30–32 vs. 26–29 in D. akaadsi), longer head (head length 29.9–33.0% SL vs. 26.7–30.1%) and longer snout-anus distance (55.8–60.4% SL vs. 51.2–54.6%) [measurements for both species modified from Kimura et al., (2013)]. Decapterus kurroides is also distinguishable from D. smithvanizi and D. tabl by having fewer cycloid scales on the curved part of the lateral line (45–52 vs. 54–62 in D. smithvanizi, 61–72 in D. tabl) and a deeper body (body depth 23.4–27.2% SL vs. 19.4–22.5%, 16.6–23.0%). A new standard Japanese name “Kitsune-akaaji” is proposed for D. kurroides.

<p>During an ichthyofaunal survey of southwestern Satsuma Peninsula, Kagoshima Prefecture, Japan, a single pompano specimen (748.0 mm standard length, 814.0 mm fork length) was collected by set net at a depth of 20 m on 24 November 2018. The specimen was subsequently identified as <i>Trachinotus anak</i> Ogilby, 1909, having the following combination of characters: dorsal-fin rays VI-I, 18; anal-fin rays II-I, 16; snout profile essentially straight immediately above upper lip; upper lip separated from snout by a continuous deep groove; a narrow band of villiform teeth on lower jaw; teeth on tongue absent; supraoccipital bone thin and blade-like; nasal and lacrimal bones hyperossified; first supraneural bone an inverted "L" shape; first to third ribs hyperossified; no distinct pattern (e.g., blotches or bands) on lateral body surface; and anal-fin lobe yellow, the anterior margin lacking brownish coloration. Because of the superficial similarity of <i>T. anak</i> to <i>T. mookalee</i> Cuvier, 1832, differentiation between the species sometimes requiring dissection, previous Japanese records of <i>T. mookalee</i> were re-examined. <i>Trachinotus mookalee</i> was confirmed as occurring in Japanese waters, but is known only from a single specimen from Miyazaki Prefecture, east coast of Kyushu, southern Japan. <i>Trachinotus anak</i> was previously known only from Taiwan, northern and eastern Australia, and New Caledonia, the present specimen from Kagoshima representing the first record from Japan and northernmost record for the species. The new standard Japanese name "Yokozunamarukoban" is herein proposed for the species.</p>

In this paper, the author presents a practical and theoretical approach to studying fish taxonomy for students and early career researchers, based on his personal experience working on the revision of threadfins-marine and freshwater fishes of the family Polynemidae. The approach is systematically arranged and described under twelve chapters, including an introduction, an insight into fish taxonomy research opportunities, and a conclusion, in the following order: Introduction; Research start-up; Writing the first taxonomic paper; Revisionary work: focus on common and widespread species; Reassessment of type specimens and original descriptions; The distributional implications of target taxa; Morphology and Ecology; Comparison between revision and review of taxonomic papers; A strategy on the order of publications; Recognizing species differences: natural aptitude or plentiful experience?; Research frontier: the numerous undescribed Southeast Asian freshwater fish species; and Conclusion.

The Duskytail Grouper, Epinephelus bleekeri (Perciformes: Serranidae), is recorded from Tanega-shima and Amami-oshima islands and the Yaeyama Islands in the Ryukyu Islands, southern Japan on the basis of six specimens (232.6-581.2 mm standard length). In addition, several records of E. bleekeri by photographs and/or observations from Kanagawa, Kochi, Ehime, Miyazaki, and Kagoshima prefectures are confirmed. Because E. bleekeri has previously been recorded from Taiwan and southward, the present specimens represent the first reliable records of the species from Japanese waters on the basis of collected specimens. Distributional implications of E. bleekeri in Japanese waters are discussed.

日本に分布するカダヤシ科グッピー属魚類には、日本各地の温泉地と琉球列島に生息するグッピー、および北海道室蘭市白老町に生息するコクチモーリーの2種が知られている。これら日本国内に生息するグッピー属魚類はいずれも人為的に導入されたものであり、本属魚類の原産地はいずれも中央アメリカである。鹿児島県の薩摩半島南部に位置する指宿市では、二反田川の南側に広がる市街を中心に多数の温泉保養施設があり、住宅地では一般家庭に温泉水が供給されている。それらの施設や住宅から排出された温泉水は、用水路を介して二反田川に流出している。鹿児島県レッドデータブックにおいて、米沢は指宿市の二反田川にコクチモーリーが生息することを目録的に報告した。しかし、本研究で指宿市のグッピー属魚類と北海道白老町産のコクチモーリーを詳細に比較したところ両者は別種であることが明らかになり、前者はPoecilia mexicana Steindachner、 1863に同定された。指宿市のP. mexicanaは二反田川の全流域にわたって、稚魚から成魚まで周年確認されており、本種は同河川で自然繁殖している。本報告では指宿市二反田川産P. mexicanaを記載するとともに、本種の成長に伴う形態の変化および性的二型を報告する。さらに本種には標準和名が与えられていないため新標準和名を提唱する。

A taxonomic review of the scorpionfish genus Scorpaenopsis in Japanese waters recognizes 12 species as valid: viz., S. cirrosa, S. cotticeps, S. diabolus, S. macrochir, S. neglecta, S. orientalis, S. oxycephala, S. papuensis, S. possi, S. ramaraoi, S. venosa and S. vittapinna. Of these, S. oxycephala, S. ramaraoi and S. vittapinna are reliably reported from Japan for the first time, including the northernrnost record of each. Distributional ranges in Japanese waters of four other species are extended, viz. S. macrochir (northernmost record from Sesoko Island off Okinawa Island, Ryukyu Islands; new record from the Ogasawara Islands), S. papuensis (northernmost record from Wakayama Prefecture; new records from Iriomote Island, Ryukyu Islands and Amamioshima, Kagoshima Prefecture), S. possi (new records from Kerama Islands and Izu Islands) and S. venosa (northern-most record from Kochi Prefecture). Three species, previously identified by Japanese researchers as S. cirrosa (Ryukyu Islands var.), S. brevifrons, S. oxycephala and Scorpaenopsis sp., are herein re-identified as S. possi, S. vittapinna, S. papuensis and S. venosa [or S. possi (part)], respectively. Five new standard Japanese names are proposed for S. macrochir, S. orientalis, S. oxycephala, S. ramaraoi and S. venosa. The configuration of a bulge on the snout and posterior nostrils found in S. macrochir constitute a newly-recognized diagnostic character for the species. Each of the above 12 species is redescribed on the basis of specimens collected from Japanese waters and compared with each other in detail. A key to the species of Japanese Scorpaenopsis is included.

A single carangid specimen (MUFS 12564, 204 mm standard length and 225 mm fork length), collected by a small set net within ca. 10 m depth at Meitsu, Nango, Miyazaki, Kyushu Island, Japan (131°23.5'E, 31°31.9'N), was identified as Trachinotus mookalee Cuvier in Cuvier & Valenciennes, on the basis of its short second dorsal fin lobe (24.0% of fork length) and anal fin coloring (lobe anteriorly yellow-golden, with weak melanophores). The specimen repre-sents the northernmost record of the species and first record from Japan. Observa-tions (at Nagasaki and Kanagawa Prefectures, Japan) of larger examples (ca. 60-90 cm in total length) of the species suggested a wide distribution around southern Japan, except the Ryukyu Islands. The specimen is described and a new Japanese name “kogane-marukoban” proposed for the species.
