Abstract

A re-examination of Luciogobius guttatus was conducted using 84 samples, which lives on all coastal waters of Korea. As a result, 41 specimens (31.3~54.4 mm SL) collected from the west and south coasts were classified as L. martellii. The morphological features of L. martellii as follows: number of abdominal vertebrae 16; total number of vertebrae 35~37; dorsal fin base length longer than upper caudal peduncle length or equal; one free ray on its upper pectoral fin; and edge of tail fin white. Among these, the most prominent morphological difference in L. guttatus is comparing the dorsal fin base length and upper caudal peduncle length, which is also well observed in syntypes of L. martellii. We proposed a new Korean name, "Geom-jeong-mi-kken-mang-duk" referring to their color.

우리나라 전 해안을 대상으로 미끈망둑 (Luciogobius guttatus)에 대한 분류학적 재검토를 실시하였다. 그 결과 41개체 (31.3~54.4 mm SL)가 L. martellii로 분류되었다. 본 종의 형태학적 특징은 다음과 같다: 복추골 수 16개; 총 척추골 수 35~37개; 등지느러미 기저부의 길이가 미병부 상부의 길이보다 길거나 같음; 가슴지느러미 상부에 1개의 유리연조; 꼬리지느러미 끝이 하얀색인 특징이 있다. 그중에서 L. guttatus와 형태학적으로 가장 뚜렷한 차이점인 등지느러미 기저부 길이와 미병부 상부의 길이의 차이는 L. martellii의 총모식표본과도 잘 일치하였다. 본 종의 한국명으로 "검정미끈망둑"을 제안한다.
