초록
Two specimens belonging to the family Mugilidae were collected from Jeju-do Island on August 7 and September 7, 2022. Based on their mitochondrial cytochrome c oxidase subunit I (COI) sequences (612 bp), they were identified as Moolgarda buchanani (Bleeker, 1853) and Osteomugil perusii (Valenciennes, 1836) respectively. M. buchanani is characterized by the origin of the first dorsal fin located nearly midway between the snout tip and the base of the caudal fin. The origin of the anal fin in directly opposite or slightly anterior to that of the second dorsal fin, and there are 32–36 lateral line scales (mainly 33–35). O. perusii is characterized by the origin of the anal fin being located anterior to that of the second dorsal fin. Other identifying features are the pelvic fin being shorter than the pectoral fin, and most parts of the second dorsal and anal fins being covered with scales. The proposed Korean names for the species are “Pa-rang-kko-ri-sung-eo” for M. buchanani and “So-mi-sung-eo” for O. perusii.
