Description
Diagnosis after Landau, Hovestadt & Silva, 2025 [35130]: Gradient monognathic heterodont. High anterior tooth lacking any ornamentation without mesial and distal cusplets, lateral teeth with small mesial and distal cusplets at the lower end of the cutting edges that are lost in posterior teeth. Teeth up to 2.5 mm wide, anterior teeth higher than wide. Main cusp triangular, elongate and lingually directed. Cusps of lateral and posterior teeth inclined towards commissure. Basal edge of the apron convex. Root holaulacorhizid and divided into two root lobes by a deep central groove with wide mediocentral foramen.
