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.

The threadfin bream genus Nemipterus Swainson, 1839 (Perciformes: Nemipteridae) currently includes 29 valid Indo-West Pacific species, eight of which have been recorded from Japanese waters. During an ichthyofaunal survey of Tanega-shima Island, Osumi Islands (Kagoshima Prefecture), Japan, a single specimen (246.9 mm standard length) of the Japanese Threadfin Bream Nemipterus japonicus (Bloch, 1791) was collected at a depth of 10 m on 13 January 2020. The specimen was characterized by seven anal-fin soft rays, 47 lateral-line scales, 6 + 10 = 16 gill rakers, a moderately deep body (depth 33.9% of standard length), long pectoral fin (posterior tip vertically level with anal-fin origin), posterior tip of depressed pelvic fin reaching between anus and anal-fin origin, upper lobe of caudal fin filamentous, and body pinkish dorsally and silver ventrally, with 1 longitudinal yellow stripes on the lateral surface, and a reddish blotch on the lateral line above the pectoral fin. Although the species is widely distributed in tropical and subtropical Indo-West Pacific waters from the Red Sea and the east coast of Africa to Taiwan and the Malay Archipelago, and bears the specific and Japanese names japonicus and Nihon-itoyori, respectively, it has at no time been recorded from Japanese waters. Therefore, the present specimen of N. japonicus, described here in detail, represents the first reliable record from Japan and northernmost record of the species in the western Pacific Ocean. The specimen collected from Tanega-shima Island was most likely to have been transported from Taiwan or the Philippines by the Kuroshio Current, the species being unlikely to reproduce in Japanese waters.

Thirty-two specimens (124.1–365.0 mm standard length) of Saurida undosquamis (Richardson, 1848) (Aulopiformes: Synodontidae), previously recorded from the Indo-West Pacific from Persian Gulf, Chagos Archipelago, Andaman Sea to Taiwan, Southeast Asia, Papua New Guinea and northern half and southwestern Australia, were collected from the mainland of Kagoshima Prefecture and Tanega-shima island in the Osumi Islands, southern Japan. These specimens represent the first records of S. undosquamis from Japanese waters and include the northernmost records (Kasasa, west coast of Satsuma Peninsula) for the species. The Japanese specimens are described here in detail and the new Japanese name “Tsukeage-eso” is proposed for the species.

<p>Two specimens (227.8–251.7 mm standard length) of the rare grouper <i>Cephalopholis polleni</i> (Bleeker, 1868) were collected off Okinawa-jima and Ishigaki-jima islands, Ryukyu Islands, the species having previously been known from scattered insular localities in the Indo-Pacific Ocean, including the Ryukyu Islands between the Amami and Yaeyama Islands. Although a single specimen of <i>C. polleni</i> had been previously obtained from a fish market in Naha, Okinawa-jima Island, its capture locality was unknown and the specimen is now apparently lost. All other Japanese records of the species were based solely on photographs. Accordingly, the present specimens of <i>C. polleni</i>, described here in detail, from Okinawa-jima and Ishigaki-jima islands represent important specimen-based records of the species from Japan, being the first with precise locality data. A review of previous distribution records of <i>C. polleni</i> from Japanese waters is also provided.</p>
