2005年在印度东北部发现了一种灵长类新种--阿鲁纳恰尔猕猴Macaca munzala，隶属于该属的中国种组，根据其外貌和分布，推测其与中国猕猴Macaca munzala亲缘关系较近。assamensis和M.藏甜菜碱我们随后获得了一个完整的成年男性标本和组织仍然从其他两个M。Munzala个人。分子分析确定了该物种的独特身份，并指出了c的起源时间。0.48该种还与异地分布的M.与M. radiata在地理上较近。assamensis和M. thibetana，可能是由来自祖先M.阿萨姆种M. thibetana股票转化为祖先M。Munzala股票。另一方面，形态计量学分析重申其仅与M. assamensis和M.据伯格曼和艾伦法则预测，在相似的生态条件下，沿着纬度梯度，可能是趋同进化的结果。(c)2007爱思唯尔公司All rights reserved.
A new species of primate, the Arunachal macaque Macaca munzala, belonging to the sinica species-group of the genus, was described from northeastern India in 2005, and, based on its appearance and distribution, hypothesised to be closely related to M. assamensis and M. thibetana. We subsequently obtained an entire adult male specimen and tissue remains from two other M. munzala individuals. Molecular analyses establish the distinct identity of the species and indicate a time of origin of c. 0.48 mya for it. The species also shows close phylogenetic affinities with the allopatric M. radiata and with the geographically closer M. assamensis and M. thibetana, possibly mediated by male introgression from an ancestral M. assamensis-M. thibetana stock into an ancestral M. munzala stock. Morphometric analyses, on the other hand, reiterate its close similarity only with M. assamensis and M. thibetana, presumably resulting from convergent evolution under similar ecological conditions and along a latitudinal gradient, as predicted by Bergmann's and Allen's rules.
