绒猴和绢毛猴，家庭Callitrichidae，是新热带灵长类动物有超过60种和亚种，栖息在南美洲大部分地区。虽然马蹄莲科的分布非常广泛，但由于分类学上的混乱和缺乏适当的统计地理学框架，试图解开它们的地理历史的努力受到了限制。在这里，我们构建了一个时间校准的多位点基因组从GenBank数据和马蹄莲文献的38个类群。我们使用这个框架进行统计学分析的Callitrichids使用BioGeoBEARS。DIVAj模型是我们的分析中最支持的地理历史重建，并表明最近的共同祖先callitrichids是广泛分布在森林地区c。十四年前。也有证据支持亚马逊盆地的大西洋森林地区的多个殖民地，首先是Leontopithecus c。11 Ma和后来的Callithrix c. 5 Ma.我们的研究结果支持了一个900万年前的分裂之间的小型团体和大型团体的绢毛猴。这些系统发育的数据，在演唱会上的一致差异，在两个群体之间的身体大小和地理模式（小体绢毛猴和大体绢毛猴有一个非常高的程度的同源物的地理重叠）借给支持我们的建议，将Saguinus分为两个属，我们建议使用不同的属名; Leontocebus和Saguinus，分别。(C)2014 Elsevier Inc.

The marmosets and tamarins, Family Callitrichidae, are Neotropical primates with over 60 species and subspecies that inhabit much of South America. Although callitrichids exhibit a remarkable widespread distribution, attempts to unravel their biogeographic history have been limited by taxonomic confusion and the lack of an appropriate statistical biogeographic framework. Here, we construct a time-calibrated multi-locus phylogeny from GenBank data and the callitrichid literature for 38 taxa. We use this framework to conduct statistical biogeographic analyses of callitrichids using BioGeoBEARS. The DIVAj model is the best supported reconstruction of biogeographic history among our analyses and suggests that the most recent common ancestor to the callitrichids was widespread across forested regions c. 14 Ma. There is also support for multiple colonizations of the Atlantic forest region from the Amazon basin, first by Leontopithecus c. 11 Ma and later by Callithrix c. 5 Ma. Our results show support for a 9 million year old split between a small-bodied group and large-bodied group of tamarins. These phylogenetic data, in concert with the consistent difference in body size between the two groups and geographical patterns (small-bodied tamarins and large-bodied tamarins have an unusually high degree of geographic overlap for congeners) lend support to our suggestion to split Saguinus into two genera, and we propose the use of distinct generic names; Leontocebus and Saguinus, respectively.
