Abstract

Eleotris oxycephala was described in detail as the first reliable record from Korea based on a single specimen (62.1 mm SL) collected from the lower reach of Jwagwang stream near Busan, Korea. The specimen is easily distinguished from three congeners occurring in the northern West Pacific by having separation between two rows of sensory papillae on opercle and the fourth row of the papillae on cheek not extending beyond the 11th longitudinal sensory-papillae.

2006년 부산시 기장군 일광읍 좌광천 하류역에서 채집된 구굴무치 Eleotris oxycephala 1개체(표준체장 62.1 mm)를 근거로 국내에서 표본에 근거한 구굴무치의 최초 기록으로서 보고한다. 본 종은 새개부 상하 공기열이 새개부 후단에서 서로 만나지 않는 점, 협부 4번째 공기열이 11번째 공기열을 넘지 않는 점 등에서 북부서태평양에 출현하는 3종의 동속 유사종과 쉽게 구별된다.
