Abstract

A specimen of Redigobius bikolanus (29.0 mm SL) belonging to the family Gobiidae was collected by a hand net from the estuary of Changgo-cheon (river) in Andeok-myeon, Jeju Island, Korea. This specimen was characterized by having 26 lateral line scales, 7 predorsal scales, 7 transverse scales, anterior oculoscapular canal, preopercular canal, and four black spots between origin of anal fin and lower origin of caudal fin. The morphological characteristics of the specimen well matched those of Redigobius bikolanus previously reported. Thus, we newly add this species to the list of Korean fish fauna and propose its new Korean name, "Jeom-bak-i-mang-duk".

망둑어과(Family Gobiidae)에 속하는 Redigobius bikolanus 1개체가 제주도 서귀포시 안덕면 창고천의 기수 지역에서 채집되었다. 이 종은 측선 비늘수 26~28개, 측선상부 비늘수 6~8개, 측선하부 비늘수 7개, 뒷지느러미 기점에서 꼬리지느러미 밑 기점까지 4개의 점이 있으며, 암컷의 경우 위턱의 뒤 가장자리가 눈의 앞부분까지 도달하며, 수컷의 경우 위턱의 뒤 가장자리가 눈을 지나는 특징을 갖고 있다. 본 종의 신한국명을 "점박이망둑"이라고 명명하였다.
