Abstract

A single specimen of Strophidon dorsalis (1,254 mm in total length), belonging to the family Muraenidae, was firstly collected in a fish trap off the coastal waters of Jindo Island in July 2018. It was characterized by having unpatterned body coloration, thin body, slightly rounded snout, two superorbital pores, three infraorbital pores, and six mandibular pores. This species is distinguishable from a morphologically similar species, S. sathete inhabiting the Korean waters by having three infraorbital pores (vs. four in S. sathete), last infraorbital pore below an anterior part of the eye (vs. below a posterior part of the eye), body depth 3.2~4.1% in total length (vs. 1.8~3.1%), and total vertebrae 154~167 (vs. 188~200). We add S. dorsalis to the Korean fish fauna and propose a new Korean name, "Seo-mang-gom-chi" for the species.

곰치과에 속하는 Strophidon dorsalis 1개체 (전장 1,254 mm)가 2018년 7월 우리나라 남해안의 진도연안에서 연안통발로 처음 채집되었다. 이 종의 특징은 몸에 무늬가 없고, 주둥이가 약간 둥근 형태를 띠며, 2개의 안상골공 (superorbital pores), 3개의 안하골공 (infraorbital pores), 그리고 6개의 하악골공 (mandibular pores)을 갖는 다. 이 종은 형태적으로 가는곰치 (Strophidon sathete)와 유사하지만 안하골공이 3개이며 (vs. 가는곰치는 4개), 마지막의 안하골공은 눈의 앞부분에 위치하며 (vs. 안하골공이 눈의 뒷부분에 위치), 전장에 대해 체고비율이 3.2~4.1%(vs. 1.8~3.1%), 그리고 척추골수가 154~167개 (vs. 188~200)로 구분할 수 있다. 이 어종의 국명은 '서망곰치'로 제안한다.
