Xenothrix macgregori had a dental formula of 2:1:3:2 on the lower jaw (Fleagle, 1988). The molars of this species had large, bulbous cusps, and the second molar is longer than the first molar (Fleagle, 1988). This species had an average body mass of around 2.0 kilograms (Fleagle, 1988).
Xenothrix macgregori was found on the island of Jamaica and occurred during the latest Pleistocene to the Recent epoch (Fleagle, 1988).
Based upon the dental morphology this was a frugivorous species or possibly consumed insect larvae like Daubentonia madagascariensis (Fleagle, 1988).
