Abstract

One specimen (619.0 mm in standard length) of Tentoriceps cristatus, belonging to the family Trichiuridae, was newly collected in the coastal waters of Jeju Island by the bottom trawl. This species was characterized by the following morphological traits: round dorsal profile of head (vs. straight for the similar species, Eupleurogrammus muticus); pelvic fin locating below the 12th dorsal fin ray (vs. 15th~17th); V, 131 dorsal fin rays; 11 pectoral fin rays; 1 pelvic fin ray changed to be a scale-like process; II anal fin rays (second one is changed to be a scale-like process). We suggest the Korean names, "Tu-gu-gal-chi-sok" and "Tu-gu-gal-chi" for the genus and species, respectively.

갈치과에 속하는 Tentoriceps cristatus 1개체(표준체장 619.0 mm)가 제주도 주변해역에서 저층트롤로 처음으로 채집되었다. 이종은 머리의 외곽이 둥근 점(유사종 분장어는 직선을 이룸), 배지느러미는 등지느러미 12번째 기조 밑에 위치하는 점(유사종 분장어는 15~17번째 기조 밑에 위치), 등지느러미 기조수가 V, 131개, 가슴지느러미 기조수가 11개, 배지느러미가 비늘형태로 변형된 점, 그리고 뒷지느러미의 극조수가 2개(2번째 극조는 비늘모양으로 변형됨)인 점이 특징이다. 본 종의 속명과 종명은 "투구갈치속"과 "투구갈치"로 각각 명명하였다.
