Homunculus vizcainoi Kay & Perry, 2019

Homunculus is an extinct genus of New World monkey that lived in Patagonia during the Miocene. Two species are known: Homunculus patagonicus and Homunculus vizcainoi, which are known from material found in the Santa Cruz Formation in the far south of Argentina.

H. patagonicus was a robustly built, quadrupedal primate, with body mass estimates varying between 1.4 and 5.9 kg (3.1 and 13.0 lb) based on different techniques.

Some authors consider Killikaike blakei to be a junior synonym for H. patagonicus, but others consider the species distinct.

While some studies have regarded Homunculus as a crown group platyrhine and a member of the family Pitheciidae, other studies have regarded it as a stem-group platyrhine outside any modern group, which is supported by the morphology of its nasal turbinates, which are dissimilar to those of crown-group platyrhines.

Homunculus is suggested to have been primarily frugivorous based on dental wear.
