A single specimen of the genus Plectorhinchus (Family: Haemulidae) was collected from the coastal waters around Jejudo Island on November 1, 2017 by a longline. The specimen was identified as Plectorhinchus vittatus by the morphological characters as follows: eight black vertical stripes on the body, scattered polka dots on the dorsal, anal and caudal fins. It is clearly distinguished from the congeneric species, P. lineatus, which is morphologically very similar to P. vittatus, in the number of gill rakers, stripes on the abdomen, and black patterns on the base of the pelvic fin. In this study, the occurrence of this species has been newly revealed at higher latitudes, suggesting the expansion of the northern distribution limit. Following Lee et al. (1999), we propose its Korean name as "Chu-sa-eo-reum-dom".
