Description
Original diagnose after Guinot et al. (2013) p. 641 [24889]: Medium-sized teeth; lingual ornamentation of slight flexuous vertical folds on lower half of the cusp of preferentially lower teeth. Anterior teeth with erect cusp and arched root branches; well-developed cutting edges in continuity with very low and inclined heels; lateral extremities of the heels bent lingually; slight labial bulge and strong lingual protuberance cut by a narrow, occasionally partly closed, nutritive groove. Lateral teeth as high as broad to broader than high in lateroposteriors; labiolingually compressed and triangular cusp with high heels that overtake the root laterally. Straight marginal root edges with a shallow notch in lateroposterior teeth. Root laterally expanded with slightly convex lingual face and subrectilinear basal edges of the branches.

Remarks
valid after Guinot et al. (2013) p. 641 [24889];
