This is the first report of Apogon erythrinus (Perciformes: Apogonidae) from Korea. A single specimen (33.6 mm SL) was collected by a fish pot from the coastal waters of Jeju-do Island on 28 October 2009. This species is characterized by having 5~6 predorsal scales, 7~9 developed gill rackers, end of second dorsal fin spine not reaching the middle of second dorsal fin base when depressed, and posterior margin of body scales reddish-brown. To confirm the correctness of species identification, the DNA cytochrome c oxidase subunit I sequence was obtained from the sample and compared with those of cardinalfish species recorded in the NCBI database. As a result, it was well-matched to A. erythrinus. We newly added this species to the Korean fish fauna and proposed a new Korean name, "Kueun-nun-eol-ge-bi-neul" because the eyes are large compared to its body.
