If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
R. A. 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
