Two specimens of Apogon unicolor (81.0 mm and 96.3 mm in standard length) belonging to the family Apogonidae were firstly collected by using a gill net from the southwestern coastal waters of Jejudo Island, Korea in July 2013. These species are characterized by having 26 lateral line pores, a first dorsal fin with 6 spines, 2+1+8=11 developed gill rackers, posterior margin of preopercle serrated, without markings and spots on the body. Our specimens are well-matched in their morphological and molecular characteristics with Apogon unicolor previously reported. Thus, we newly add this species to the Korean fish fauna and propose its new Korean name "Jin-hong-eol-ge-bi-neul" because the overall fish body and fins reveal deep red colors.
