Three specimens (33.6-44.8 mm in standard length) of the family Bregmacerotidae, collected from the waters off south-western Jeju-do Island in October 2016, were identified as Bregmaceros nectabanus on the basis of morphological and molecular methods (DNA barcoding). This species is characterized by having 50-52 2nd dorsal fin rays, 52-53 anal fin rays, 13 principal caudal fin rays, an unpigmented abdomen, irregularly distributed dorsal chromatophores, and the origin of a dorsal fin slightly behind the anal fin. This is the first reliable record of B. nectabanus in Korea. According to Yoo et al. (1992), we propose a Korean name "Tae-Pyeong-Yang-Nal-Gae-Myeol" for this species. Also, we suggest key to species of these eight bregmacerotids from the northwestern Pacific.
