利用线粒体DNA（mtDNA）部分序列分析了日本西部低地广泛分布的小型鲤（Hemigrammocypris rasborella）的遗传群体结构。分子系统发育分析表明，九州西部地区的人口显着分化，从所有东部人口，这样的群体将是可比的不同物种，他们的分歧被推断发生在晚中新世上新世。此外，在三洋和四国东北部地区发现了一个很大程度上不同的mtDNA组（在更新世早期出现分歧），在近畿西部与东部mtDNA组形成了次级接触带。迄今为止，这些方面的人口结构的H。在日本西部的低地鱼类中，鱼似乎是独一无二的。要更深入地了解日本西部淡水动物群的形成过程，就需要进一步比较组成物种的地理格局和生态特征。
The genetic population structure of the small cyprinidHemigrammocypris rasborella, distributed widely in lowlands of western Japan, was examined using partial sequence data of mitochondrial DNA (mtDNA). Molecular phylogenetic analysis revealed that the populations of the western Kyushu region were markedly differentiated from all eastern populations, such that the groups would be comparable to different species; their divergence was inferred to have occurred in the Late Miocene–Pliocene. Also, a largely divergent mtDNA group (with divergence in the early Pleistocene) was found in the Sanyo and northeastern Shikoku regions, forming a secondary contact zone in the western Kinki with the eastern mtDNA group. To date, these aspects of the population structure ofH. rasborellaappear to be unique among lowland fishes in western Japan. Deeper understanding of the formation processes of freshwater faunas in western Japan will require further comparisons of the phylogeographic patterns and ecological traits of constituent species.
