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).

Two species of lefteye flounder (Bothidae), Engyprosopon mozambiquense Hensley, 2003 and Engyprosopon parvipectorale Amaoka and Ho, 2018, are newly recorded from Japan based on five specimens (one male and four females) and a single male specimen, respectively, from Nakagusuku Bay, Okinawa Island, Ryukyu Islands. The two species resemble each other in sharing the following combination of characters: extremely narrow interorbital space; large mouth (posterior margin of ocular side upper jaw extending beyond anterior margin of lower eye); inner margin of gill rakers with serrae; and a pair of dark blotches on caudal fin absent. However, the present male specimen of E. mozambiquense differed from male specimens of E. parvipectorale from Taiwan and Japan in having a greater interorbital width, 11.5 in head length (vs. 23.1–67.7 in male E. parvipectorale), a rostral spine on the ocular side of the snout (vs. absent), and three dark blotches on the ventral surface of the ocular side lower jaw (vs. uniformly black). The present female specimens of E. mozambiquense were characterized by having small teeth on both jaws (vs. anterior teeth on the upper jaw, and all teeth on the lower jaw large and canine-like in both male and female E. parvipectorale). The two species are also similar to the Japanese endemic congener, Engyprosopon kushimotoense Amaoka, Kaga and Misaki, 2008 (known only from the male holotype from Wakayama Prefecture), and Engyprosopon longipelvis Amaoka, 1969 (known from southern Japan) in having gill rakers with serrae and a narrow interorbital space. However, E. kushimotoense and E. longipelvis differ from the former in having 43 and 37–42 lateral-line scales, respectively (vs. 49–52 in E. parvipectorale and 46–52 in E. mozambiquense). The new standard Japanese names “Yorime-darumagarei” and “Kiba-yorime-darumagarei” are proposed here for E. mozambiquense and E. parvipectorale, respectively.

The labrid genus Suezichthys Smith, 1958 includes 11 valid species, four of which have been recorded from the Japanese waters. Three specimens (125.2–137.7 mm standard length) of the Northern Rainbow Wrasse Suezichthys notatus (Kamohara, 1958) were collected from Tosa Bay and the East China Sea. These specimens possess the following characters: dorsal-fin rays IX, 11; anal-fin rays III, 10; scale rows above lateral line 2 1/2; lateral-line scales 25, each with unbranched laterosensory canal tube; and dark brownish blotches on head and body above pectoral fin. Suezichthys notatus, distributed in scattered localities of the eastern Indian Ocean and the Pacific Ocean, has been recorded only from Okino-shima island, Kochi Prefecture, on the basis of a holotype in the Japanese waters. Therefore, the present specimens represent the second records of the species from Japan.

A single specimen (636.0 mm disc width) of the Pink Whipray Pateobatis fai (Jordan and Seale, 1906) (Dasyatidae) was collected off the south coast of the Satsuma Peninsula, Kagoshima Prefecture, Kyushu, Japan. Although the tail had been removed after capture, the specimen was subsequently identified based on disc morphology and molecular analysis. In Japanese waters, the species has previously been recorded only from Chichi Island (Ogasawara Islands), Okinawa Island (Okinawa Islands), and Iriomote Island (Yaeyama Islands), The present specimen, described here in detail, therefore representing the first record of P. fai from the Japanese mainland, and the northernmost record for the species.

The pipehorse genus Solegnathus Swaison, 1839 is divided into two subgenera, Solegnathus Swaison, 1839 (superior trunk ridge discontinuous, with superior tail ridge) and Runcinatus Whitley, 1929 (ridges continuous), the former including Solegnathus (Solegnathus) hardwickii (Gray, 1830), S. (S.) lettiensis Bleeker, 1860, S. (S.) spinosissimus (Günther, 1870), and S. (S.) robustus McCulloch, 1911, and the latter, S. (Runcinatus) dunckeri Whitley, 1927. Of these five species, only S. (S.) hardwickii and S. (S.) lettiensis, have been recorded to date from Japanese waters, the latter being known from only two specimens [259.6 mm and 284.6 mm total length (TL)], both reported from the middle of the Okinawa Trough, southern East China Sea in 1978. However, a single specimen (KAUM–I. 182558, 367.0 mm TL) of S. (S.) lettiensis was found on a beach on Kamikoshiki-shima Island, Koshiki Islands, northern East China Sea, Kagoshima Prefecture, Japan in December 2022, probably a discarded bycatch from a deepwater bottom trawl fishery operating off the island. The specimen was characterized by having the superior trunk ridge discontinuous, with a superior tail ridge; opercular membrane without bony side platelets; body surface mainly tuberculate; length of dorsal-fin base 1.41 in head length; 23 trunk rings; and 74 total rings, and its identification confirmed after comparison with the two previously-collected specimens (above). The former, representing the second Japanese record and northernmost record of S. (S.) lettiensis, is described herein in detail, and the new standard Japanese name “Shinkai-sumitsuki-yoji” proposed for the species.

Two specimens (201.6–205.9 mm standard length) of Hippocampus spinosissimus Weber, 1913 (Gasterosteiformes: Syngnathidae), previously recorded from the Indo-West Pacific from India east to the Philippines, north to Taiwan, and south to northern Australia, were collected at a depth of 20 m off Tanega-shima Island, Osumi Islands, Kagoshima Prefecture, southern Japan. These specimens, described here in detail, represent the first records from Japan and the northernmost record for the species. A new standard Japanese name “Tamayori-tatsu” is proposed for the species.

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.
