Wortman united the Anaptomorphidae with the Tarsiidae in the group 

 Palaeopithecini, and these again with the Ardopithecini-IIapale on the one hand 

 and the Neopithecini-Adapidae, Cebidae, Cercopifhecidae, Simiidae and Hominidae 

 on the other, in the suborder Anthropoidea as opposed to the other Primates — 

 Gheiromyoidea and Lem- 

 uroidea. In any case ^ 



the Anaptomorphidae 

 are closely related to 

 the Tarsiidae.
