In this paper, we report the findings of a comparative study of the elbow joints of five species of macaque that inhabit China: Macaca assamensis, M. arctoides, M. mulatta, M. thibetana and M. nemestrina. Results of multivariate analyses of size-related variables and indices of the elbow joint suggested that the breadths of the ventral aspect of the trochlea and of the medial epicondyle of the humerus as well as indices describing the head of the radius are important factors for discriminating these species. The elbow joint of M. arctoides was most similar to that of M. thibetana, no doubt reflecting recency of common ancestry and similarity in terrestrial locomotion. The structures of the elbow joints in M. nemestrina and M. assamensis seemed more adapted to arboreal quadrupedalism. The elbow joint of M. mulatta, however, appears intermediate between the most terrestrial and the most arboreal forms.
在本文中，我们报告了对栖息于中国的五种猕猴（熊猴、藏酋猴、恒河猴、藏猕猴和豚尾猴）肘关节的比较研究结果。对与肘关节大小相关变量和指标的多变量分析结果表明，滑车腹侧宽度、肱骨内侧髁宽度以及描述桡骨头的指标是区分这些物种的重要因素。熊猴的肘关节与藏猕猴的最为相似，这无疑反映了它们最近的共同祖先关系以及在陆地运动方面的相似性。豚尾猴和熊猴的肘关节结构似乎更适应树栖四足行走。然而，恒河猴的肘关节则介于最适应陆地生活和最适应树栖生活的类型之间。
