摘要

A juvenile specimen, 59.2 mm standard length (SL), of the ammodytid genus Ammodytoides was collected with a midwater trawl off Cape Ashizuri-misaki, Kochi Prefecture, Shikoku Island, Japan. This specimen has the following combination of characters: dorsal fin rays 48; anal fin rays 22; pectoral fin rays 15; pored lateral line scales ca. 95; gill rakers 5 + 22 = 27; vertebrae 33 + 24 = 57; head length 25.3% SL; predorsal length 26.7% SL; caudal peduncle depth 5.7% SL; 2 supratemporal pores; pale orange-red body with blackish dorsal and anal fins posteriorly when fresh. Among the 10 valid congeners, this specimen is similar to A. gilli (Bean, 1895) (tropical eastern Pacific), A. kimurai Ida and Randall, 1993 (Ogasawara Islands) and A. kanazawai Shibu-kawa and Ida, 2013 (Ogasawara Islands) in most counts and proportions, but differs from them by the combination of coloration when fresh, and counts of lateral line scales and supratemporal pores. The validity of A. kanazawai described from a juvenile is also discussed.
