A new genus for the extinct Hispaniolan monkey Saimiri bernensis Rímoli, 1977 : with notes on its systematic position. American Museum novitates ; no. 3134

The extinct Hispaniolan primate heretofore known as Saimiri bernensis is distinct in numerous ways from true squirrel monkeys and all other known Recent mainland platyrrhines. We therefore remove it to a new genus, Antillothrix. Parsimony analysis of 32 craniodental characters indicates that the closest known relative of Antillothrix is the newly described (and likewise extinct) Cuban platyrrhine Paralouatta varonai (supported by 5 unambiguously placed synapomorphies of maxillary fourth premolar and maxillary and mandibular first molars). The sister group ofAntillothrix and Paralouatta is Callicebus (supported by 3 unambiguously placed synapomorphies of mandibular and maxillary canines). This clade is sister to a grouping consisting of extant atelids and Stirtonia (sister-group arrangement supported by 1 unambiguously placed synapomorphy, large zygomaticofacial foramen relative to buccolingual breadth of maxillary first molar).
