| 内容記述 | A single specimen (275.8 mm standard length) of Saurida macrolepis Tanaka, 1917, distributed in the western Pacific Ocean, was collected from Amami-oshima island, Amami Islands, Ryukyu Islands, Japan. In Japanese waters, S. macrolepis has previously been recorded from Japanese mainland (from Wakasa Bay and Chiba Prefecture to southern Kyushu), and the East China Sea. Thus, the Amami specimen, described herein in detail, represents the first reliable record of S. macrolepis from the Ryukyu Islands. The Amami specimen had shorter pectoral fins and more distinct black spots along the upper margin of the caudal fin than those of S. macrolepis from Japanese mainland and the East China Sea. Examination of specimens of this species from Vietnam, the Philippines, and Malaysia showed that the above-mentioned two characters of specimens from Vietnam were consistent with those of Japanese mainland and the East China Sea, and specimens from the Philippines and Malaysia agreed with the Amami specimen. Although the two characters are different between specimens from the eastern Eurasian Continent (Japanese mainland, East China Sea, and Vietnam) and Southeast Asia (Philippines and Malaysia), molecular analysis shows no significant differences among them; thus we regard that the morphological and color differences indicate geographic variations within a species. The Amami specimen is considered here to be transported by the Kuroshio Current from the Philippines. Saurida macrolepis can be distinguished from other Japanese congeners by the following combination of characters: lateral-line scales 46–50 (usually 48 or 49); vertebrae 45–49; posterior end of pectoral fin just reaching or extending beyond P–D line; scale pockets below lateral line, 2–3 scale rows with melanophores; single row of distinct or indistinct black spots along caudal-fin upper margin or else uniformed black; and lower margin of caudal fin white. | |||||||||||||
