 | | Also the traditional cebid-callitrichid dichotomy is radically altered: Cebinae, consisting of Cebus (capuchin monkeys) and Saimiri (squirrel monkeys), is the sister of Callitrichinae and these two subfamilies constitute the family Cebidae. |
 | | We plan to gather extensive additional DNA sequence data in order to test the congruent branching arrangements of the epsilon and IRBP maximum parsimony trees, especially those arrangements that are controversial when compared to the cladistic evidence from previous morphological studies (11-14). |
 | | Thus we plan to further test the cladistic validity of proposed taxonomic groupings (20,21,24) that reflect congruent epsilon and IRBP results (but not all morphological results) such as a subfamily Cebinae (Cebus, Saimiri), a family Cebidae (Cebinae, Aotus, Callitrichinae), a subfamily Pitheciinae (Callicebus, Pitheciini), a subtribe Brachytelina (Brachyteles, Lagothrix), and a tribe Atelini (Ateles, Brachytelina). |
