First Record of the Genus Oedoparena (Diptera: Dryomyzidae) from Korea with a Key to the World Species

In this paper, we record Oedoparena Curran, 1934, a previously unreported genus discovered on the west coast of Korea, for the first time in Korea, along with a newly recorded species, Oedoparena minor Suwa, 1981. Until now, this genus comprised only three species worldwide, all distributed exclusively along the cool, maritime coasts of the Northern Pacific, from Far East Asia to North America. Furthermore, most larvae of this genus are known to be predators of barnacles in the intertidal zone. We provide photographs of external features, illustrations of male genitalic structures, and a diagnosis of the newly recorded species, along with a key for worldwide species.
