Primates: Xenotrichidae

      The single species, P. varonai, is known only from Cuba. The largest of the Antillean monkeys, with a body wieght of approximately 12 kg, it has been suggested that this animal may have been partially terrestrial. There are currently no pertinent radiocarbon dates that bear on the question of when P. varonai became extinct. Closely related to Xenothrix of Jamaica and Antillothrix of Hispaniola.
