Abstract

Redescription of the Hawaiian ladyfish Elops hawaiensis was carried out based on four specimens collected from Busan and Gwangyang between 2008 and 2010. This species has a gular plate between the symphysis and isthmus, and the entire premaxillary tooth band is exposed when the mouth is closed. Our Korean specimens of E. hawaiensis are characterized by having 65~67 vertebrae, 14 anal fin rays and 95~101 lateral line scales, which values differed slightly from those given in previous studies. Molecular analysis using 4S0 base pairs of mitochondrial DNA cytochrome b sequences showed that our four specimens corresponded well with E. hawaiensis (99.8~100.0%). Therefore, our results suggest that there may exist regional differences in vertebrae and anal fin ray counts for E. hawaiensis.

2008~2010년 사이에 우리나라 부산 및 광양에서 채집된 당멸치, Elops hawaiensis 4개체의 형태특정을 상세히 재기재하였다. 본 종은 아래턱의 봉합부와 협부 사이에 후판을 가지며, 입을 닫았을 때 전상악골의 치대 전체가 노출된다. 한국산 당멸치는 척추골수이 65~67개, 뒷지느러미 연조수가 14개, 측선비늘이 95~101개를 가지는 것이 특징적이었으며 이전 연구결과와 약간 달랐다. 미토콘드리아 DNA cytochrome b 480 bp의 염기서열을 분석한 결과, 우리의 4개체는 E. hawaiensis와 99.8~100% 일치하였다. 따라서, 우리 결과는 당멸치가 척추골 및 뒷지느러미 계수에서 지역적 변이가 존재할 것이라는 사실을 제시한다.
