Abstract

Three specimens of Abudefduf septemfasciatus were collected firstly from tidal pools on the southern and northern coasts of Jeju Island, Korea in August 2015. This species is characterized by black blotches on the upper origin of the pectoral fin, upper caudal peduncle and a dorsal fin between the second and fourth spines, predorsal scales beyond to above the middle of the eye, 12~13 soft dorsal and anal fin rays, and 20 lateral-line scales. This species is distinguishable from Abudefduf sordidus by soft dorsal and anal fin rays, location of caudal peduncle blotch, and location of the dorsal fin blotch. The newly proposed Korean name is "Il-gop-jul-ja-dom".

2015년 8월, 우리나라 제주도 남부 및 북부 연안 조수웅덩이에서 Abudefduf septemfasciatus 3개체가 처음 채집되었다. 본 종은 가슴지느러미 기점 위, 꼬리자루 위 및 2번째와 4번째 등지느러미 극조 사이에 검은 반점이 있고 등지느러미 전방 비늘은 눈의 중앙을 지나며, 등지느러미 및 뒷지느러미 연조는 12~13개, 측선비늘은 20개이다. 본 종은 줄자돔과 등지느러미 및 뒷지느러미 연조수, 꼬리자루 반점 위치 및 등지느러미 반점 위치에서 차이를 보인다. 본 종의 새로운 국명으로 '일곱줄자돔'을 제안한다.
