Abstract

Three specimens (56.7~92.4 mm in standard length) of the small psychrolutid Psychrolutes pustulosus (Schmidt, 1937) were collected by bottom trawl in the coastal waters off Pohang, the southern East Sea, Korea. This species is characterized by large cephalic pores, no markings on the body or fins, no spines on the head, and no notch between the spiny and soft-rayed dorsal fin. We describe specimens the southernmost distribution in the world, and compare them with two congeneric species from Russia. We thus present the first record of Psychrolutes pustulosus (Schmidt, 1937) within the Korean fish fauna and propose the new Korean name "Min-mu-nui-mul-su-bae-gi" for this species.

쏨뱅이목 물수배기과에 속하는 Psychrolutes pustulosus 3개체 (표준체장 56.7~92.4 mm)가 포항 해역에서 저층 트롤로 채집되었다. 이 소형종은 두부에 큰 감각공이 산재하고 몸이나 지느러미에 무늬가 없고 두부에 가시가 없으며 등지느러미 극조부와 연조부에 결각이 없이 연결되는 것이 특징이다. 이 어종을 우리나라 어류상에 최초로 포함시키고 국명으로 "민무늬물수배기"를 제안한다.
