( Mohanamico herskovitzi gen. et sp. nov., a middle Miocene South American primate).
Mohanamico hershkovitzi was about the size of the living squirrel monkey Saimiri sciureus. Its molars are low-crowned and the molar crests are not pronounced suggesting a frugivorous diet like Aotus. The lateral incisor is large and high-crowned, which foreshadows living Pitheciinae. The canines and P2 were large and sharp like Callimico. Our analysis of the mandible and teeth suggest that Mohanamico is a primitive member of the Pitheciinae. Some similarities with Callimico and Saguinus are also noted raising the possibility that pithecines and callitrichids are monophyletic.
