Abstract

Taxonomic review of the five flyingfishes, Parexocoetus mento (Valenciennes), Cheilopogon agoo (Temminck et Schlegel), Cheilopogon heterurus doederleini (Steindachner), Cheilopogon cyanopterus (Valenciennes), Hirundichthys oxycephalus (Bleeker) were carried out based on samples collected from the South sea and around sea of Jeju Island of Korea from 1996 to 1998. Parexocoetus mento (Valenciennes) and Cheilopogon cyanopterus (Valenciennes) were revealed as the unrecorded species in Korea, which were named as "Men-to-hwang-nal-chi" and "Ki-geom-nal-chi" respectively. Parexocoetus mento is differed from P. barchypterus in having no chin barbels in juveniles, and Cheilopogon cyanopterus is distinguished from C. agoo in the branched form of pectoral fin rays and from C. heterurus doederleini in the numbers of the dorsal fin ray and the color of pectoral fins.

한국 남부해 및 제주도 주변해역에서 1996~1998년의 3년간 채집된 날치류 5종, Parexocoetus mento (Valenciennes), Cheilopogon agoo (Temminck et Schlegel), Cheilopogon heterurus doederleini (Steindachner), Cheilopogon cyanopterus (Valenciennes), Hirundichthys oxycephalus (Bleeker)에 대하여 분류학적 위치를 재검토하였다. Parexocoetus mento 및 Cheilopogon cyanopterus는 국내에서 처음으로 보고되는 종으로 P. mento는 "멘토황날치", C. cyanopterus는 "기점날치"로 명명하였다. P. mento는 유어기에 아래턱 선단에 돌기를 가지지 않는 점에서 황날치 P. brachypterus와 잘 구별되며, C. cyanopterus는 날치 Cheilopogon agoo와는 가슴지느러미줄기의 분지형태, 전력날치 Cheilopogon heterurus doederleini와는 등지느러미 줄기수 및 가슴지느러미 색깔에서 잘 구별된다. 본 조사에서 날치과 어류는 우리나라 제주도 주변해역에서 남부해에 걸쳐 6월부터 9월까지 출현하는 것으로 나타났다.
