초록
A single specimen (108.12 mm standard length) of the family Pinguipedidae was collected using a Danish seine off Seogwipo-si, Jeju-do Island, Korea, on February 27, 2024. The specimen was identified as Parapercis decemfasciata (Franz, 1910), characterized by having 4 dorsal fin spines, yellow fins (except the pectoral fin when fresh), a continuous dorsal fin without a notch, 10 narrow transverse bands on the body, and 4 dark transverse bands on the caudal fin. This species closely resembles its congeneric counterpart, Parapercis multifasciata. However, they can be differentiated by the number of dorsal fin spines (4 in P. decemfasciata vs. 5 in Parapercis multifasciata), the presence of a black spot at the base of the caudal fin (absent vs. present), and the relative size of the snout and pupil (pupil larger vs. snout larger). Molecular analysis of 529 bp of mitochondrial DNA cytochrome c oxidase subunit I sequences showed that our specimen perfectly corresponded to those of P. decemfasciata from NCBI GenBank. Consequently, we believe this represents a reliable record of P. decemfasciata from Korea, and we propose adopting the Korean name “No-rang-yeol-dong-ga-ri” as suggested by Kim et al.
