Abstract

A single specimen (700 mm in disc length) of Plesiobatis daviesi, belonging to the family Plesiobatididae, was firstly collected in the north-eastern coastal waters of Jejudo Island, Korea by using a bottom trawl on 24 October 2010. This species was characterized by having five pairs of gill openings, tail with one to three large spines, long snout length, long caudal fin, and pleated margin of nasal curtain. It is morphologically similar to Urolophus aurantiacus, but the former is distinguished from the latter by having longer caudal fin and snout length. We add P. daviesi to the Korean fish fauna and suggest the new Korean names, "Gin-kko-ri-huin-ga-o-ri-gwa", "Gin-kko-ri-huin-ga-o-ri-sok" and "Gin-kko-ri-huin-ga-o-ri" for the family, genus and species, respectively.

매가오리목, 긴꼬리흰가오리과 (신칭)에 속하는 Plesiobatis daviesi 1개체 (체반장 700 mm)가 2010년 10월 11일 제주도 동북쪽 연안 (해구번호 110)에서 저인망에 처음으로 채집되었다. 이 종은 5쌍의 아가미 구멍이 있는 점, 꼬리에 1~3개의 가시가 있는 점, 주둥이가 긴 점, 꼬리지느러미가 긴 점, 그리고 코 끝에 커튼 모양의 주름이 있는 점이 특징이다. 그리고 형태적으로 흰가오리와 유사하지만, 흰가오리보다 꼬리지느러미 길이와 주둥이 길이가 상대적으로 긴 특징을 갖는다. 이 미기록종의 과명과 속명 그리고 종명은 "긴꼬리흰가오리과", "긴꼬리흰가오리속" 그리고 "긴꼬리흰가오리"로 각각 제안한다.
