绒猴和绢毛猴（Cebidae，Callitrichinae）是新世界猴中物种最丰富的亚科，也是表型最多样的亚科之一。尽管该组的分子遗传学丰富，表型性状的进化下迅速出现的一致性遗传学的亚科一直很少研究，导致分类学的建议，有有限的支持，从其他数据集。我们研究了18个表型性状（5个连续和13个离散）的进化，包括皮毛，头骨，牙列，postcrania，生活史和发声变量在一个强大的分子系统发育的绒猴和绢毛猴，量化它们的系统发育信号和一些性状之间的相关性。在家庭层面上，我们得到的拓扑支持猫头鹰猴（Aotinae）的姐妹组Callitrichinae。的callitrichine树的拓扑结构是一致的，与以前的研究，除了的位置的midas组的Saguinus绢毛猴，放置作为姐妹的双色组没有得到显着的统计支持，在最大简约和贝叶斯推理分析。结果表明，在连续性状中，长呼性状的系统发育信号值最高，家域性状的系统发育信号值最低，与骨骼学和头骨大小相关的性状的系统发育信号值居中。在离散性状中，皮毛和骨骼具有相似的系统发育信号。基于遗传学、骨骼学、皮毛学和发声学数据，我们提出了一个更新的属级分类学的Callitrichinae，其中承认6个属的亚科：Callimico，Callithrbc，Cebuella，Mico，Leontopithecus和Saguinus。为了反映其表型的独特性，并避免使用非正式的“种组”，我们细分Saguinus在亚属Leontocebus，Saguinus和Tamarinus（重新验证这里）。
Marmosets and tamarins (Cebidae, Callitrichinae) constitute the most species-rich subfamily of New World monkeys and one of the most diverse phenotypically. Despite the profusion of molecular phylogenies of the group, the evolution of phenotypic characters under the rapidly-emerging consensual phylogeny of the subfamily has been little studied, resulting in taxonomic proposals that have limited support from other datasets. We examined the evolution of 18 phenotypic traits (5 continuous and 13 discrete), including pelage, skull, dentition, postcrania, life-history and vocalization variables in a robust molecular phylogeny of marmoset and tamarin monkeys, quantifying their phylogenetic signal and correlations among some of the traits. At the family level, our resulting topology supports owl monkeys (Aotinae) as sister group of Callitrichinae. The topology of the callitrichine tree was congruent with previous studies except for the position of the midas group of Saguinus tamarins, which placement as sister of the bicolor group did not receive significant statistical support in both Maximum Parsimony and Bayesian Inference analyses. Our results showed that the highest value of phylogenetic signal among continuous traits was displayed by the long call character and the lowest was exhibited in the home range, intermediate values were found in characters related to osteology and skull size. Among discrete traits, pelage and osteology had similar phylogenetic signal. Based on genetic, osteological, pelage and vocalization data, we present an updated genus-level taxonomy of Callitrichinae, which recognizes six genera in the subfamily: Callimico, Callithrbc, Cebuella, Mico, Leontopithecus and Saguinus. To reflect their phenotypic distinctiveness and to avoid the use of the informal "species group", we subdivided Saguinus in the subgenera Leontocebus, Saguinus and Tamarinus (revalidated here).
