Cultriculus kneri and C. eigenmanni previously described as genus Cultriculus were the junior synonym of Hemiculter leucisculus(Basilewsky) and H. eigenmanni (Jordan et Metz) respectively. Differences in the number of lateral line scales and gill rakers further distinguish these two species of the genus Hemiculter. Hemiculter leucisculus has distributed in the two rivers of the Han and the Imjin, and their around reservoirs, and H. eigenmanni has inhabited widely in the middle and lower courses of the Anso＾˘ng-river (include the Suwon) , the Ku＾˘ m, the Man` gyo＾˘ng, the So＾˘mjin, the Yo＾˘ngsan rivers and their around reservoirs.
