Abstract

This is the first report of Cantherhines pardalis (Tetraodontiformes: Monacanthidae) from Korea. A single specimen (105.4 mm in SL) was collected from the coastal waters of Busan by gill net on 20 June, 2012. This species is characterized by having the following morphological traits: II, 34 dorsal fin rays; 31 anal fin rays; 13 pectoral fin rays; caudal peduncle without large spines; spine row on the lateral side of first dorsal spine distinct; posterior end of pelvic with encasing scales distinctly more protruding than ventral flap. This species is similar to C. dumerilii except for the number of spines on caudal peduncle (none in C. pardalis vs. two pairs in C. dumerilii). Based on morphological and molecular approaches, the specimen was identified as C. pardalis. We add C. pardalis to Korean fish fauna and propose the new Korean names "Yuk-gak-mu-nui-jwi-chi" for the species.

쥐치과에 속하는 Cantherhines pardalis 1개체(표준체장 105.4 mm)가 2012년 6월 20일에 부산 연안에서 자망에 처음으로 채집되었다. 이 종은 등지느러미 기조수 II, 34개를 갖는 점, 뒷지느러미 기조수 31개를 갖는 점, 가슴지느러미 기조수 13개를 갖는 점, 꼬리지느러미 미병부에 큰 가시가 없는 점, 첫 번째 등지느러미 극조 측면에 분명한 거치가 있는 점, 그리고 흉부 말단에 딱딱한 비늘이 돌출되어 있는 특징을 갖는다. 그리고 이 종은 형태적으로 검은쥐치(C. dumerilii)와 유사하지만 꼬리지느러미 비병부에 가시가 없어서, 2쌍의 가시를 가지는 검은쥐치와 형태적으로 쉽게 구분된다. 또한 유전학적 방법을 사용하여 이 표본이 C. pardalis임을 확인하였다. 우리나라에서 처음 보고되는 이 종을 한국 어류상 목록에 추가하였고, 국명으로 "육각무늬쥐치"를 제안하였다.
