摘要
依据倒刺属内部骨骼和外部形态特征，结合其地理分布．首次探讨了该属鱼的物种分化与区域地理演变历史的关系。研究结果表明，倒刺属鱼类共有３个共同离征。其一级姐妹群的分布范围在中国东南沿海地区有较大的重叠。二级姐妹群的分化与云贵高原的抬升和相应的水系分流有密切的关系。三级和四级姐妹群的分化主要是由于生活环境的差异所致。
Based on the interior and outer morphological characters as well as the geographical distributions, the interspecific differentiations of Spinibarbus fishes have been studied in the present paper with referrence to regional geographical development history. The investigation results reveal that the Spinibarbus fishes share 3 synapomorphies. The distribution ranges of the first pair of sister groups overlap greatly each other. The phyletic division of second pair of sister groups is supposed to be correlated to the uplift of Yunnan-Guizhou Plateau and the subsequent drainages' subdivision. The phyletic split of the 3rd pair of sister groups and the 4th pair of ones should be resulted from the habitat's differentia.
