Abstract

Based on a single specimen (49.9 mm SL) collected from Incheon River estuary, south-western Korea, Gymnogobius cylindricus was described as the first record from Korea as well as the westernmost record of the world. The species is characterized by having a large maxilla extend far beyond posterior margin of eye, dorsal fin with VI-I, 12 rays, anal fin with I, 11 rays, and without dark blotches and dots on lower part of body and caudal fin, respectively. A new Korean name, "Ga-neunsal-mang-dug" is proposed for the species.

우리나라 서남부의 인천강 하구역에 설치된 실뱀장어잡이 그물에서 망둑어과 꾹저구속 Gymnogobius cylindricus 1개체(표준체장 49.9 mm)가 채집되어 한국미기록종 및 분포의 서방한계로 보고한다. 본 종은 머리가 납작하며 몸이 가늘고 긴 점, 등지느러미 기조수가 VI-I, 12, 뒷지느러미 기조수가 I, 11, 체측의 어두운 반점열이 몸의 복부에 도달하지 않는 점 및 꼬리지느러미 하방에 반점열이 없는 점이 특징이다. 본 종의 신한국명으로 "가는살망둑"을 제안한다.
