Upper jaw teeth with one main cusp and one pair of asymmetrical lateral cusplets of different height, elongated lingual bulge below the crown pierced by a central foramen. Root contour squared or distally rounded with a medio-lingual foramen and a nutritive groove. Lower jaw teeth monocuspid with short, stocky main cusp inclined distally. Mesial cutting edge sigmoid, distal cutting edge straight. Mesial root edge straight and displaced below the crown, rounded root contour on the distal edge. One central foramen situated on the bulge, one medio-lingual foramen is developed below and a nutritive groove occurs. Numerous labial foraminal openings follow the basal crown edge.
