Abstract

Based on four specimens (50.9~69.0 mm SL) collected from a small stream of southern coast of Jeju Island, Eleotris acanthopoma was described as the second Eleotris species as well as the first record from Korea. They were characterized by having two dorsal fins, well-separated pelvic fins, separation of two rows of sensory papillae on opercle and extending the fourth row of sensory papillae beyond the 13th longitudinal sensory-papillae row on cheek. We proposed a new Korean name, "Geom-eun-gu-gul-mu-chi", for the species.

2013년 제주도 남부 연안으로 유입되는 소하천에서 구굴무치과(Eleotridae) 구굴무치속(Eleotris)에 속하는 어류 4개체(표준체장 50.9~69.0 mm)를 채집하였다. 이들은 등지느러미가 2개이며 배지느러미가 서로 유합하지 않고 분리되어 있는 점, 새개부 상하 공기열이 새개부 후단에서 서로 만나지 않는 점, 협부 4번째 공기열이 13번째 공기열을 지나 하방으로 신장하는 점 등에서 E. acanthopoma로 동정되었다. 본 종은 이러한 특징에서 북부 서태평양 해역에 분포하는 구굴무치를 포함한 같은 속의 유사종과 쉽게 구별되며, 신한국명으로는 체색이 대체로 흑색인 점에서 '검은구굴무치'를 제안한다.
