In order to resolve the taxonomic contusion of Acheilognathus limbata from Korea, 17 morphological characters, egg form and cleavage part of A. limbata from Japan and Korea were ompared. These two groups are overlapping each other in morphometric characters mostly, but two characters of snout length and interarbital width percent in head length are distinguished between them. Moreover the Korean and the Japanese specimens are significantly different from each other based on the egg form and, cleavage part of egg. These results indicate that A. limbata from Korea and from Japan are homonyms. So we consider that the target specimens from Korea should be treated Acheifognathus sp. rather than Acheilognathus limbata until further informations are available.
