MORPHOLOGY: Mahgarita stevensi has relatively small premolars and molars with well-developed crests (Fleagle, 1999). This species has a dental formula of 2:1:3:3 on both the upper and lower jaw (Martin, 1990). The mandibular symphysis is fused and the snout is deep in this species (Fleagle, 1999). This species has an average body mass of 600 grams (Fleagle, 1999).
RANGE: Mahgarita stevensi lived in North America and occurred during the late Eocene (Fleagle, 1999). This is the only cercamoniinae found in North America (Fleagle, 1999).
Based on dental morphology this species most likely had a folivorous diet (Fleagle, 1999).
