Abstract

The Eyebar goby, Gnatholepis cauerensis is reported firstly from Korea, based on four specimens (36.3~47.1 mm in SL) collected at depth range of 12~16 m in the southern coastal waters of Jejudo Island, Korea. They are characterized by having mostly ctenoid scales on body, head including cheek, opercle, and middle of predorsal region with cycloid scales, and a unique coloration of yellow blotch with marginally black marking above pectoral fin base as well as transverse black bar below eye. A new Korean name, "Geom-eun-nun-ddi-mang-dug", is proposed for the species.

우리나라 제주도 남부 연안의 수심 12~16 m에서 채집된 4개체(36.3~47.1 mm in SL)의 표본들을 근거로 망둑어과 어류, Gnatholepis cauerensis을 한국첫기록종으로 보고한다. 본 종은 몸의 대부분이 빗비늘으로 덮여 있지만, 뺨과 아가미뚜껑, 그리고 등지지느러미 앞 중앙 부분은 둥근비늘로 덮여 있는 점, 가슴지느러미 기부 위에 가장자리가 검정색인 노란색 반점과 눈 아래의 흑색 가로줄무늬가 있는 것이 특징이다. 본 종의 신한국명으로 '검은눈띠망둑'을 제안한다.
