Description
Original diagnose after Siverson (1993) p. 10 [2213]: Upper jaw teeth with very large lateral cusplets, reaching half the height or more of cusp. Labial face of crown very flat, without ornamentation. Flat, V-shaped basal face of root with two axial foramina or with infundibulum. Rectangular lower jaw teeth longer than high. Separate axial foramina; occasionally forming infundibulum. No disto-lingual foramen. Interlocking hollows poorly developed, especially in juveniles.
