The classification and phylogenetic relationships of the snub-nosed langurs (Rhinopithecus) are still open questions. We have sequenced a mitochondrial cytochrome b gene fragment from R. roxellana, R. bieti, R. avunculus and Presbytis phayrei. There are 47 sites (19%) characterized by variation. A series of evolutionary trees with concordant topology has been derived by using parsimony, maximum likelihood and distance methods, which may have resolved the evolutionary relationships of the three golden monkey species. R. bieti is more closely related to R. avunculus than to R. roxellana. The divergence among those three species occurred about 2-6 million years ago. Our results suggest that Rhinopithecus is a valid genus, and avunculus should be placed into this genus. Our non-invasive genetic analysis provided useful information for the genetic management of the captive population at the Kunming Institute of Zoology.
仰鼻猴属（Rhinopithecus）的分类及系统发育关系仍是有待解决的问题。我们测定了来自川金丝猴（R. roxellana）、滇金丝猴（R. bieti）、越南金丝猴（R. avunculus）和菲氏叶猴（Presbytis phayrei）的线粒体细胞色素b基因片段序列。共有47个位点（19%）存在变异。运用简约法、最大似然法和距离法构建了一系列拓扑结构一致的进化树，这些进化树可能已解决了三种金丝猴物种的进化关系。滇金丝猴与越南金丝猴的亲缘关系比与川金丝猴更近。这三个物种之间的分化发生在约200万至600万年前。我们的结果表明仰鼻猴属是一个有效的属，越南金丝猴应归入该属。我们的非侵入性遗传分析为昆明动物研究所圈养种群的遗传管理提供了有用信息。
