中文摘要	the complete 1140 bp mitochondial cytochrome b sequences were obtained from 39 individuals representing five species of all four genera of highly specialized schizothoracine fishes distributed in the qinghai-tibet plateau. sequence variation of the cytochrome b gene was surveyed among the 39 individuals as well as three primitive schizothoracines and one outgroup. phylogenetic analysis suggested that the group assignment based on 1140 bp of the cytochrome b sequence is obviously; different from previous assignments, and the highly specialized schizothoracine fishes (schizopygopsis pylzovi, gymnocypris przewalskii, g. eckloni, chuanchia lablosa, and platypharodon extremus) form a monophyletic group that is sister to the clade formed by the primitive schizothoracine fishes (schizothorax prenanti, s. pseudaksaiensis, and s. argentatus). the haplotypes of schizopygopsis pylzovi and g. przewalskii were paraphyletic based on cytochrome b data, which most likely reflected incomplete sorting of mitochondrial dna lineages. the diploid chromosome numbers of schizofhoracinae were considered in phylogenetic analysis and provided a clear pattern of relationships. molecular dating estimated for highly specialized schizothoracine fishes suggested that the highly specialized schizothoracine fishes diverged in the late miocene pliocene to pleistocene (4.5x10(4)-4.05x10(6) years bp). the relationship between the cladogenesis of highly specialized schizothoracine fishes and geographical events of the qinghai-tibet plateau is discussed.
