초록

수중 집어등에 의한 제주도 북부 연안역 자치어 조사 과정에서 2004년부터 2007년 사이에 채집된 도치과 어류 5개체 (표준체장 9.8~ 17.9 mm)에 근거로 Lethotremus awae를 한국미기록종으로 기재하였다. 이들의 체형은 구형으로 두부에 3개의 수염과 유사한 관상 돌기가 있는 점, 제1등지느러미가 기조수를 세기 어려울 정도로 두꺼운 피부로 덮혀 있는 점, 등지느러미 기조수 VIII-9, 뒷지느러미 기조수 8~ 9, 가슴지느러미 기조수 22~23인 특징이 있다. 본 종의 신한국명으로는 크기가 작은 점에서 '엄지도치'라 명명한다.

Five specimens of Lethotremus awae (Cyclopteridae) were collected from the northern coastal waters of Jeju Island, Korea, during a survey on larval and juvenile fishes flocking to aquatic lamp in 2004 ~ 2007. They were characterized by having a spherical body with three barbel-like tubes on head and the first dorsal fin overgrown by skin with undiscernible rays as well as VIII-9 dorsal fin rays, 8 ~ 9 anal fin rays and 22 ~ 23 pectoral fin rays. A new Korean name, "Eom-ji-do-chi", was proposed for the species.
