A single specimen (196.4 mm standard length) of the scorpaenid Hozukius emblemarinus was collected by a bottom trawl from the coastal waters off Ulsan, East Sea, Southern Korea. The specimen is characterized by a deep oblong body, three spines on the lower margin of the eye, a dorsal fin with 12 spines, a head mostly covered with various sizes of scales, and a truncate posterior margin of the caudal fin. This is the first record of H. emblemarinus in Korea; we therefore add the species to the Korean fish fauna and propose the new Korean name, "Dong-hae-keun-nun-bol-rak" for this species.
