A specimens of Hippichthys spicifer (Rüppell, 1838) (92.7 mm in standard length) were collected from Jeju Island, Korea on July 19, 2023. The species is well distinguished from Hippichthys heptagonus by the number of trunk rings between the anus and dorsal fin (two in H. spicifer vs one) and the presence of black stripes on the abdomen (present in H. spicifer vs absent). It is also distinguished from Hippichthys penicillus by the direction of the lateral median trunk ridge (deflected in H. spicifer vs. straight). Mitochondrial DNA cytochrome c oxidase subunit I sequences (436 bp) showed a 99.1% match with H. spicifer. As this is the first record of such species in Korea, we suggest a Korean name “Jul-mu-nui-sil-go-gi”.
