抄録

A single specimen of Chromis earina Pyle, Earle and Greene, 2008, previously known from Puluwat westward to Palau, and southward to Papua New Guinea, Indonesia, Vanuatu and Fiji, was collected from Iou-jima Island, Kagoshima Prefecture, Japan at a depth of 80 m. A second example of the species was photographed at a depth of 70 m in the same locality. The collected specimen was characterized by the following combination of characters: XIII dorsal-fin spines; II, 12 anal-fin rays; 18 pectoral-fin rays; 3 spiniform caudal rays; 6 + 20 = 26 gill rakers; and a poorly-defined, broad, white vertical band, its width subequal to that of 3 or 4 scales, on the mid-lateral surface of the body when alive. The specimen represents the first record of C. earina from Japan and is the northernmost record of the species.
