Abstract

Based on three specimens (50.6~67.7 mm SL) collected from the southern coastal waters of Jejudo Island, Oxycheilinus bimaculatus was described as the first record from Korea. They were characterized by having two small dark spots behind eye on head and body posterodorsally, a rhomboid caudal fin with elongated central rays and produced uppermost ray as a filament in terminal male, six predorsal scales, and two scale rows on cheek. We proposed a new Korean name, "Du-jeom-gin-ju-dung-i-nol-rae-gi", for the species referring to having two dark spots on head and body.

우리나라 연안성 어류자원 미발굴 분류군 탐색을 위해 제주도 남부 연안해역에서 SCUBA를 이용한 수중조사 중 2015년 11~12월에 수심 약 17 m 부근에서 놀래기과 한국미기록종인 Oxycheilinus bimaculatus 3개체 (표준체장 50.6~67.7 mm)를 채집하였다. 본 종은 체형이 길쭉한 계란형으로 체고가 다소 낮아 두장보다 작은 점, 아래턱이 위턱보다 약간 긴 점, 눈의 후단과 가슴지느러미 후상방에 2개의 소형 흑색 반점이 있는 점, 성숙한 수컷의 꼬리지느러미 상부와 중앙의 기조가 실처럼 신장하는 점, 등지느러미 극조부 전반부가 검고, 등지느러미와 뒷지느러미 가장자리에 작은 흑색 반점이 산재하는 특징에서 동속 타종과 쉽게 구별된다. 본 종의 신한국명으로 체측에 2개의 흑색 반점이 있는 점에서 '두점긴주둥이놀래기'를 제안한다.
