利用19只新大陆猴的ϵ-珠蛋白基因序列(代表所有现存的16个头猴属)和7种卡他目动物(1只东半球猴和6个人科动物)和眼镜猴作为外类群，研究了新大陆猴总科16个现存属之间的系统发育关系。对这些ϵ-珠蛋白序列发现的共识最大简约树以及简约分析和自举分析对该树中的分支的支持水平，为分支分类提供了强有力的证据，如下所示。Callitrichina(Callithrix，Cebuella)、Callimicina(Callimico)、Leontopithecina(Leontopithecus)和Saguina(Saguinus)亚族组成Callitrichinae亚科，Callitrichinae、Aotinae(Aotus)、Saimiriinae(Saimirinae)和Cebinae(Cebus)组成Cebinae科。依次，Chiropotina(Chiropotes，Cacajao)和Pitheciina(Pithecia)组成Pithecini，Pitheciinini和Callicebini(Callicebus)组成Pitheciinae亚科，Atelini(Brachyteles，Lagothrix，Ateles)和Alouattini(Alouatta)组成Atelinae亚科，Pitheciinae和Atelinae亚科组成Atelinae。这两个科(Cebiae和Atelidae)构成了Ceboidae，这是扁形目中现存的唯一超家族。Brachyteles和Lagothrix，Sguinus和Leontopithecus，Callimico与Cebuella/Callirix分支的姐妹群关系不是很好地被简约和Bootstrap分析所支持。因此，这些关系不包括在拟议的分支分类中。在仅从ϵ-珠蛋白基因座更自由进化的非编码序列中确定头骨类系统发育树的分支长度，并以3500万年前为新大陆猴-卡他龙分支点的参考年龄时，我们估计该分支点的年龄约为20MYA，下一个分支点的年龄为19-16MYA。
Phylogenetic relationships among the 16 extant genera of Ceboidea (the New World monkeys) were examined using aligned ϵ-globin gene sequences from 19 New World monkeys (representing all 16 extant ceboid genera), and seven catarrhines (one Old World monkey and six hominoids) and tarsier as the outgroups. The consensus maximum parsimony tree found for these ϵ-globin sequences and the levels of support from parsimony and bootstrap analyses, for the clades in this tree, provided strong evidence for a cladistic classification with the following clusters. Subtribes Callitrichina (Callithrix,Cebuella), Callimiconina (Callimico), Leontopithecina (Leontopithecus), and Saguina (Saguinus) constitute subfamily Callitrichinae, and subfamilies Callitrichinae, Aotinae (Aotus), Saimiriinae (Saimiri), and Cebinae (Cebus) constitute family Cebidae. In turn, subtribes Chiropotina (Chiropotes,Cacajao) and Pitheciina (Pithecia) constitute tribe Pithecini, tribes Pitheciini and Callicebini (Callicebus) constitute subfamily Pitheciinae, tribes Atelini (Brachyteles, Lagothrix, Ateles) and Alouattini (Alouatta) constitute subfamily Atelinae, and subfamilies Pitheciinae and Atelinae constitute family Atelidae. The two families (Cebidae and Atelidae) constitute the Ceboidea, the only extant superfamily of infraorder Platyrrhini. The sister-group relationships ofBrachytelesandLagothrix,SaguinusandLeontopithecus, andCallimicowith aCebuella/Callithrixclade is not as well supported by the parsimony and bootstrap analyses. Therefore, these relationships are not incorporated in the proposed cladistic classification. On determining branch lengths for the ceboid phylogenetic tree from only the more freely evolving noncoding sequences at the ϵ-globin locus and taking the reference age of 35 million years ago (MYA) for the New World monkey-catarrhine branch point, we estimated the age of the atelid-cebid branch point as about 20 MYA, and the ages of the next branch points, those between the sub-families in each family, as 19-16 MYA.
