초록

The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.
