The distribution patterns of seven Cobitis species are analysed, namely, C. takatsuensis, C. biwae, the yamato complex, the Kyushu form of C. striata (small race), C. striata (middle race), the Hakata form of C. striata (middle race), and the Onga form of C. striata (middle race) in the northern Kyushu Island Japan. C. takatsuensis is distributed in the upstream areas of some rivers in the northeastern part of the island. The yamato complex is widely distributed in the northern part of the island. The other five species are distributed in five areas separated by mountains. Although the yamato complex and the four striata complex species are often distributed in the same river system, the former inhabit upstream areas, while the latter inhabit the downstream reaches. The results of this study reveal that habitat fragmentation by mountains and the difference in longitudinal distribution lead to this complicated distribution pattern.
