Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae. The total analysis strongly supports the monophyly of the Cebidae family, grouping Aotus, Cebus and Saimiri with the small callitrichines. In the callitrichines, the data link Cebuela to Callithrix, place Callimico as a sister group of Callithrix/Cebuella, and show Saguinus to be the earliest offshoot of the callitrichines. In the family Pithecidae, Callicebus is the basal genus. Finally, combined molecular data showed congruent branching in the atelid clade, setting up Alouatta as the basal lineage and Brachyteles-Lagothrix as a sister group and the most derived branch. Two major points remain to be clarified in the platyrrhine phylogeny: (i) what is the exact branching pattern of Aotus, Cebus, Saimiri and the small callitrichines, and (ii), which two of these three lineages, pitheciines, atelines or cebids, are more closely related?
四个DNA数据集串联组合（6700碱基对），并进行了最大简约法和邻接法分析。结果表明几乎同时出现了三个类群：蛛猴科、僧面猴科和卷尾猴科。总体分析有力地支持了卷尾猴科的单系性，将夜猴属、卷尾猴属和松鼠猴属与小型狨猴类归为一组。在狨猴类中，数据将塞布埃拉狨与狨属联系起来，将伶猴属作为狨属/塞布埃拉狨的姐妹群，并表明柽柳猴属是狨猴类中最早分化出来的。在僧面猴科中，伶猴属是基部属。最后，综合分子数据显示蛛猴科分支具有一致性，将蛛猴属作为基部谱系，将绒毛蛛猴属 - 长毛蛛猴属作为姐妹群和最衍生的分支。阔鼻猴系统发育中仍有两个主要问题有待阐明：（i）夜猴属、卷尾猴属、松鼠猴属和小型狨猴类的确切分支模式是什么，以及（ii）这三个谱系中的哪两个，僧面猴类、蛛猴类还是卷尾猴类，关系更密切？
