Two species of the genus Koreocobitis in Korea are reviewed with a key to species and their illustrations: Koreocobitis rotundicaudata and K. naktongensis sp. nov. A new species, Koreocobitis naktongensis is described based on 9 specimens collected from the Naktong River, Korea. The new species is distinguished from Koreocobitis rotundicaudata by the following combination of characters: yellow body colouration with many brownish speckles, truncate caudal fin, fewer vertebrae, and longer head. It is remarked biogeographically that Koreocobitis naktongensis is distributed only in the Naktong River, Korea.
