Abstract

Sixteen specimens of Artediellus fuscimentus, belonging to the family Cottidae, were collected from the coastal waters off Samcheok and Donghae, Korea, in December 2010 and February 2015, respectively. The specimens are characterized by four preopercular spines, 12~13 second dorsal fin rays, 10~12 anal fin rays, a first preopercular spine with no minute spine on the inner side, and pectoral fin extending past the origin of the anal fin. We also analyzed 600 base pairs of the mitochondrial DNA cytochrome b sequence to confirm the taxonomic status of the specimens. The sequences of our specimens corresponded completely to those of Japanese A. fuscimentus, but differed from those of A. atlanticus (d=0.057~0.061). We propose the new Korean names "Eom-ji-hoet-dae-sok" for the genus Artediellus and "Eom-ji-hoet-dae" for the species A. fuscimentus.

2010년 12월 4일 강원도 동해시에서 15개체, 2015년 2월 1일 강원도 삼척시에서 1개체의 Artediellus fuscimentus가 처음 채집되었다. 본 종은 전새개골 가시 4개, 제2등지느러미 줄기 12~13개, 뒷지느러미 줄기 10~12개를 가지며, 첫번째 전새개골 가시 안쪽에 작은 가시가 없고 가슴지느러미 뒤끝이 뒷지느러미 기점을 지나는 특징을 가지고 있다. 또한 mtDNA cytochrome b 염기서열 600 bp를 이용하여 분류학적 위치를 확인하였다. 그 결과, 본 종은 Artediellus atlanticus와 차이(d=0.057~0.061)를 보였으나, 일본산 A. fuscimentus와는 완전히 일치하였다. Artediellus속의 국명으로 "엄지횟대속"을, A. fuscimentus의 국명으로는 "엄지횟대"를 새롭게 제안한다.
