中文摘要	Rhinogobio is a cyprinid genus restricted to the river drainages of China. Sequences of the mitochondrial DNA control region were determined for four Rhinogohio species and one outgroup species, Coreius heterodon, to investigate the phylogenetic relationships within the genus. The control region of the Rhinogobio species ranges from 922 to 930 base pairs and comprises 930 base pairs in Coreius. Our phylogenetic analysis indicates two distinct lineages in the genus Rhinogobio. The first includes only R. ventralis. In the second lineage there are three species, two closely related species R. cylindricus and R. hunanensis, and their sister species R. typus. An analysis of character adaptations suggests an evolutionary trend in this genus towards a relatively lower body and caudal peduncle depth, a shorter dorsal fin, and a more anterior anus. In addition, there is a trend towards shorter barbels and relatively larger eyes. Some or all of these traits may be associated with a habitat shift from fast-flowing turbid rivers to slower-flowing clear river habitats.
