The study on phylogeny of the sinocyclocheiline fishes (Cypriniformes: Cyprinidae: Barbinae)

The sinocyclocheiline fishes are endemic group distributing in Ynnan-Guizhou Plateau and northern Guangxi Provice, China. Phylogenetic relationgships of the sinocyclocheiline fisher are studied with cladistic analysis and Barbodes is selected as the out-group. The result indicates that the sinocyclocheiline fishes are a monopheletic group which consists of two major phyletic lines, and the varition of the frontal, the scale number and among 19 species of the sinocyclocheiline fishes are analysed on the information of external characters and skeleton characters with clustering methods, which are identical with the result of cladistic analysis. Sinocyclocheilus can be divided two subgenera: Snocyclocheilus Fang s. str. and Gibbibarbus Dai.
