<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>

Four specimens (390.5–576.0 mm standard length; SL) of Etelis boweni Andrews, Fernandez-Silva, Randall and Ho, 2021 (Perciformes: Lutjanidae), collected from the Osumi Islands, Kagoshima Prefecture, Japan, were similar to Etelis carbunculus Cuvier, 1828 in sharing the following characters: dorsal fin with a deep notch and lacking scales; maxilla covered with scales; caudal-fin lower lobe whitish; and length of caudal-fin upper lobe greater than 3.3 in SL. However, the specimens differed from E. carbunculus in having the opercular spine posterior end rounded (pointed in the latter), 14 scale rows below the lateral line (vs. 12), and tip of the caudal-fin upper lobe black in both fresh and preserved specimens (vs. reddish in fresh specimens, yellowish in preserved specimens). Furthermore, a sequence analysis of the mitochondrial cytochrome oxidase I gene of the four Osumi Islands’ specimens showed a divergence of only 0.0–0.5% from the holotype of E. boweni, the five specimens comprising a clade separated by 7.5–8.8% sequence divergence from E. carbunculus. Although E. boweni is widely distributed in the IndoWest Pacific (from the Red Sea and Seychelles to Samoa), the Osumi Islands’ specimens (for which the standard Japanese name “Oo-akamutsu” is newly proposed) represent the first specimen-based records of Etelis boweni from Japanese waters as well as from the northwestern Pacific Ocean. Additionally, the apparently sympatric occurrence of E. boweni and E. carbunculus was evidenced by the collection together of the two species (KAUM–I. 160343, 390.5 mm SL and KAUM–I. 160342, 407.9 mm SL, respectively).

A single specimen (166.0 mm standard length) of Peristedion riversandersoni (Alcock, 1894) (Teleostei: Peristediidae), previously recorded in Japanese waters from off Toyama Prefecture in the Sea of Japan, the Pacific coast from Ibaraki to Miyazaki prefectures, and the East China Sea, was recently collected from off Iwate Prefecture, northern Japan. This specimen representing the northernmost record for P. riversandersoni is described herein. In addition, coloration of fresh and preserved specimens of P. riversandersoni are emphasized as newly recognized diagnostic characters for this species based on a comparative examination of 29 specimens of P. riversandersoni, including the Iwate specimen, with 70 specimens of Peristedion orientale Temminck and Schlegel, 1843.

A single specimen (153.7 mm total length) of large congrid leptocephalus, collected at a depth of 400 m off Kuro-shima Island, Osumi Islands, Kagoshima Prefecture, Japan, was subsequently identified as Congriscus maldivensis (Norman, 1939), having the following combination of characters: 46 lateral-line pores before anus; 149 total vertebrae, including 46 abdominal vertebrae; maximum body depth 27.2% of total length (TL); pectoral fin length 40.6% of head length; highest margin of head profile anterior to pectoralfin base; snout rounded, its tip anterior to tip of lower jaw; maxilla and mandibular teeth conical, uniserial; anterior nostril with short membranous tube, below snout margin; posterior nostril rounded, anterior to eye; posterior end of mouth posterior to vertical through middle of eye; cephalic sensory pores and lateral line developed; anus slightly anterior to middle of body; dorsal, anal, pectoral, and caudal fins present (dorsal-, anal-, and caudal-fin membranes fused); and dorsal fin origin slightly posterior to ventral through pectoral-fin base. A neighbor joining tree based on mtDNA cytochrome c oxidase subunit I (COI) gene sequences placed the specimen within a clade of C. maldivensis, based on previously published sequences, thereby supporting its conspecificity with C. maldivensis. The specimen was tentatively determined as a metamorphic larva, based on the following features: 153.7 mm TL, head length 12.7% of TL, and body opaque, with melanophores around the midline. An Indo-West Pacific species, C. maldivensis has previously been recorded from Tanzania to the Philippines, Wallis and Futuna Islands, and Australia, the present specimen therefore representing the first Japanese record and northernmost record of the species. The new standard Japanese name “Nan’you-okianago” is proposed for the species.

A single specimen [411.5 mm total length (TL)] of the Short-tail Brown Moray Gymnothorax pseudoprolatus Smith, Hibino and Ho, 2018 was collected at a depth of 27 m off Kasasa, Minami-satsuma, Kagoshima Prefecture, Japan. The specimen possessed the following characters: 75 pre-anal vertebrae; 175 total vertebrae; maxillary teeth biserial anteriorly and uniserial posteriorly; dentary teeth uniserial; 6 mandibular pores; head length (HL) 11.1% of TL; pre-dorsal length 8.6% of TL; body depth at gill opening 4.1% of TL; body uniformly brown; and lips whitish. Although G. pseudoprolatus is most similar to Gymnothorax prolatus Sasaki and Amaoka, 1991, it differs from the latter in having a longer pre-anal region (pre-anal length 50.0–53.6% of TL vs. 48–51% in G. prolatus), shorter snout (snout length 17.8–20.7% of HL vs. 20.0–23.8%), 6 mandibular pores (vs. 7), 75–78 pre-anal vertebrae (vs. 79–83), and 169–175 total vertebrae (vs. 182–187). In addition, analysis of the mitochondrial cytochrome oxidase I (COI) gene of both species showed them to be separated by 3.2–3.8% average sequence divergence. Gymnothorax pseudoprolatus has been previously known only from the holotype from Taiwan. Therefore the Kagoshima specimen represents the first record from Japanese waters and the northernmost record for the species. The new standard Japanese name “Chairo-utsubo” is proposed for the species.

The triplefin genus Ceratobregma Holleman, 1987 includes two valid species, the Spotted Spiny-eye Triplefin C. acanthops (Whitley, 1964) and Helen’s Triplefin C. helenae Holleman, 1987. Both are characterized by the first dorsal fin having 3 spines, the anal fin 2 spines, and the pelvic fin with one spine and 2 rays, in addition to discontinuous lateral lines (upper series of tubular pored scales and lower series of notched scales), well developed lateral ethmoids, 3 or 4 spines on the anterior margin of the orbit in males, and a scaleless opercle and pectoral-fin base. Ceratobregma acanthops is known only from the Coral Sea, whereas C. helenae is widely distributed in the eastern Indian and western Pacific oceans. A single specimen (KAUM–I. 146836, 24.3 mm standard length) of C. helenae collected from Kume-jima Island, Okinawa Islands, Ryukyu Archipelago, Japan in October 2020 possessed the following characters: first spine of 1st dorsal-fin shorter than that of 2nd dorsal-fin; caudal peduncle narrow; sides of body with orange vertical bands; and 2nd dorsal fin with a basal series of orange spots. Previous records of the species from Japan include a single specimen (BPBM 8723, 29.6 mm standard length) collected from Taketomi-jima Island, Yaeyama Islands in 1968, and underwater photographs (as Ceratobregma sp.) taken at Irabu-jima and Miyako-jima Islands, Miyako Islands, in 2002 and 2004, respectively. The two Japanese specimens were examined, that from Kume-jima Island (described in detail) representing the northenmost record for the species. The new standard Japanese name “Mikan-hebigimpo” is proposed for C. helenae on the basis of the Kume-jima specimen, “Mikan-hebigimpo-zoku” serving for the genus Ceratobregma.

<p>A comparison of 68 specimens of <i>Plectranthias</i> (Serranidae: Anthiadinae) from Japanese waters with 85 Indo-Pacific specimens, all characterized by the fourth dorsal-fin spine longest, no branched pectoral-fin rays, two antrorse spines on the lower preopercular margin, the lateral line incomplete with fewer than 22 pored scales, and scales absent from the maxilla, revealed the former to include <i>P. longimanus</i> (Weber, 1913) [23 specimens, 8.5–28.4 mm standard length (SL)], <i>P. nanus</i> Randall, 1980 (38, 10.6–32.3 mm SL), and <i>P. winniensis</i> (Tyler, 1966) (7, 24.1–38.6 mm SL). Among the Japanese specimens, <i>P. longimanus</i> was similar to <i>P. nanus</i> in overall body appearance, but differed from the latter in having modally 12 pectoral-fin rays [vs. 13 in <i>P. nanus</i>], 15 gill rakers (vs. 17), 14 pored lateral-line scales (vs. 18), 26 or 27 scale rows in the longitudinal series (vs. 28), 8 scale rows below the lateral line (vs. 9), 3 interopercular spines (vs. spines absent), and 2 or 3 subopercular spines (vs. spines absent), a maximum body depth 34.1% (mean) of SL (vs. 28.6%), and a vertical band absent near the base of the caudal fin (vs. band present in both fresh and preserved specimens). Japanese <i>P. winniensis</i> clearly differed from the other two species, having 16 or 17 soft rays in both the dorsal and pectoral fins (vs. fewer than 15 rays in the latter two species), modally 16 pored lateral-line scales (vs. 14 in <i>P. longimanus</i>, 18 in <i>P. nanus</i>), subopercular spine absent (vs. 1–4 present in <i>P. longimanus</i>), and a greenishred body without dark blotches or bands (vs. reddish-brown body, mottled with dark blotches and bands). In addition, analyses of 12S ribosomal RNA and cytochrome c oxidase subunit I gene sequences indicated that the three species were genetically distinct from each other. In Japanese waters, <i>P. longimanus</i> has been recorded from the Izu Peninsula and the Izu Islands to the Koshiki Islands, mainland Kagoshima, and the Ryukyu Islands, <i>P. winniensis</i> having a similar distribution pattern, i.e., from the Izu Islands south to the Ryukyu Islands. <i>Plectranthias nanus</i> has been recorded only from island groups, including the Ogasawara, Ryukyu, and Daito islands.</p>

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.

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.
