A Taxonomic Revision of the Subfamily Gobiinae(Pisces, Gobiidae) from Korea

한국산 망둑어아과 어류의 분류학적 재검토

Thirty three species belonging to twenty genera in the subfamily Gobiinae of Korea were reviewed and key to species and genera were provided. Among them twenty seven species captured during 1985-1987 were examined on the cephalic sensory canal systems for the taxonomic review, and classified into 4 groups based on the presence or absence of the canal and their canal pore patterns. It was confirmed that the pore patterns of preopercular and anterior ocular-scapular canal were important in the diagnosis of gobiid genera or species and in the discussion of the specialized species group. It was considered that the genus of Acentrogobius masago should be transferred to Pseudogobius from Acentrogobius, because A. masago was more similar to P. jausnicus than to A. pflaumi and its congeneric species in their cephalicc sensory canal systems. Some populations of Chaenogobius annularis and Acanthogobius lactipes showed the geographical variations in cephalic pit organs and the number of predorsal scales. The endemic gobiid species was not found the Korean waters, but some species showed a disjunct distributions between the west and the east coast waters in Korea. The south coast was inhabited by the abundant species including twenty seven species of seventeen genera. The genera of Acanthogobius, Chaenogobius, and Chasmichthys were considered to be the common genera in Korean waters.

한국산 망둑어아과 어류를 20속 33종으로 분류하고 속${\cdot}$종검색표를 작성하였다. 채집된 망둑어 아과 어류 16속 27종에 대하여 종별 전${\cdot}$후안견갑관과 전새개관의 유무 혹은 개공 서열구상을 비교하여 4 groups으로 구분하였으며, 이것을 근거로 하여 계통 유연관계를 논의였다.전새개관개공배열구상은 속의 구분과 일치하였고, 전안견갑관개공의 소실정도는 속내의 특화된 종이나 종군을 찾아내는데 유의하였다. Pscudogobisu masago는 후안견갑관과 전새개관이 없는 점에서 Acentrogobius 속과는 구별된다고 본다. Chaenogobius annularis, Chaenogobius casteneus 및 Acanthogobius lactipes는 두부감각관계와 predorsal scales의 수에 있어서 지리적 변이를 보여 주었다. 망둑어아과 어류의 한국고유종은 발견되지 않았으나, 동해연안과 서해연안의 어류상은 잘 구분되었으며, 남해연안에서 17속 26종이 출현하고 있어 가장 다양한 분포상을 보였다. 우리나라 연안의 망둑어아과어류의 우점속은 Acanthogobius Chaenogobius 및 Chasmichthys 속이었다.
