Abstract

A single specimen of Strophidon sathete (1,302 mm in total length), belonging to the family Muraenidae, was collected in a danish seine off the southern coast of Jejudo Island in April, 2019 for the first time. It was characterized by having unpatterned coloration and thin body, snout slightly rounded, three superorbital pores, four infraobital pores, and six mandibular pores. This species is distinguishable from morphologically similar Gymnothorax albimarginatus inhabiting Korean waters by having all fins dark (vs. fins dark posteriorly with white margin for latter), body depth 1.8~3.1% in total length (vs. 3.2~5.7%), and no dark band on head in less than 50~70 cm (vs. exist). We add Strophidon sathete to the Korean fish fauna and propose a new Korean name, "Ga-neun-gom-chi" for the species because the body is relatively thinner than other similar moray species (G. albimarginatus) in Korea.

곰치과에 속하는 Strophidon sathete 1개체(전장 1,302 mm)가 2019년 4월 제주도 남방 해역에서 외끌이 기선저인망으로 처음 채집되었다. 이 종의 특징은 무늬가 없고, 몸이 가늘며, 주둥이 약간 둥근 형태를 띠며, 3개의 안상골공(superorbital pores), 4개의 안하골공(infraobital pores), 그리고 6개의 하악골공(mandibular pores)을 갖는다. 형태적으로 가지굴(Gymnothorax albimarginatus)과 유사하지만 등지느러미와 뒷지느러미가 전체적으로 어둡고(vs. 말단에 하얀색을 띰), 전장에 대해 체고비율이 1.8~3.1% (vs. 3.2~5.7%), 그리고 전장이 50~70 cm보다 작을 때 반문이 없는 것(vs. 반문이 있음)으로 구분할 수 있다. 따라서 몸의 굵기가 유사종에 비해 상대적으로 가는 형태적 특징에 근거해서 이 미기록종의 국명을 "가는곰치"로 제안한다.
