Abstract

Based on the 14 specimens collected from the Korean waters, we described the external morphology of Ocynectes maschalis in detail to provide morphological characteristics for species identification. The species from Korea is characterized by having a low first dorsal fin with a dark spot posteriorly, no dark blotches ventrally, three saddle-like blotches on dorsal midline posterior to the second dorsal fin, and two occipital cirri on head.

우리나라 주변해역에서 채집된 둑중개과 가시꺽정이 14개체를 근거로 종 동정을 위해 외부 형태적 특징을 상세히 기재했다. 본 종은 제1등지느러미가 낮고 그 후방에 흑색 반점이 있는 점, 복부에 암색 반점이 없는 점, 제2등지느러미 후방에서 꼬리지느러미 기부에 이르는 등쪽 정중선을 따라 3개의 암색 안장 모양의 반문이 있는 점, 그리고 후두부에 2쌍의 피변이 있는 점에서 유사종인 '민가시꺽정이'와 쉽게 구별된다.
