2013년 9월 8일 제주도 서귀포시 예래동 조간대에서 뜰채로 채집된 나비고기과 유어 1개체를 형태 분석한 결과, 등지느러미 연조부에 커다란 눈 모양의 반점을 가지는 점에서 Chaetodon vagabundus로 동정되었다. 또한, 분자 분석을 통해 얻은 COI 572 bp 염기서열을 NCBI에 등록된 염기서열과 비교한 결과, C. vagabundus와 100% 일치하였다. 본종의 새로운 국명으로 “황줄나비고기”를 제안한다.
A single specimen of Chaetodon vagabundus Linnaeus, 1758 belonging to the family Chaetodontidae was collected on September 8, 2013 in Yerae-dong, Seogwipo-si, Jeju Island, Korea. The morphological characteristics of C. vagabundus are similar to C. auriga and C. auripes in having dark vertical stripes cross the eye, but differs from C. auriga, which has high dorsal fin extended between spine and soft rays without concavity and has blotch of circle in dorsal fin, and from C. auripes which has yellow body, big of eye proportion and a black stripe along the caudal peduncle during the immature stage. C. vagabundus has eye-like black spots on dorsal fin and black vertical stripe extended from the anterior dorsal soft ray to the middle of the anal fin along the caudal peduncle. Molecular analysis results showed that our specimen perfectly matched C. vagabundus in the mitochondrial DNA COI sequences. Therefore, we use the Korean name, “Hwang-jul-na-bi-go-gi” for C. vagabundus proposed by Kim et al. (2020).
