Stirton 1951Fossa diagastrica not present; fossa genioglossi not apparent, surface convex dorsoventrally along symphyseal line between incisor alveoli borders and torsustransversus superior; spina mentalis sharply defined; mandibular rami more divergentthan in recent ceboid genera; lingual surface of lateral incisorwith basal cingulum; canine much higher and larger than p2; p2 without metaconid, only slightly larger then p3; anterorbital cingulum prominent on m1; m2 as large as m1 but with different outline; alveolus indicates very little reduction in m3
