dentition. Cusps and reentrants are spaciously open, ectomesolophid is extremely short and crescentic, occlusal morphology is simplified and a mesolophid is absent, The m1 anteroconid is simplified as a small compressed and narrow cusp. The m3 is conspicuously reduced and lacks an entoconid. Dentition is parallel to the axis of the mandible.
