Description
Original diagnose after Siverson (1995) p. 6 [2214]: (lower antero-lateral teeth) Teeth up to at least about 47-49 mm wide (estimated original size of RM P8706) with straight (males?) or strongly convex (females?) mesial cutting edges on acrocone. Distal cones with convex mesial cutting edges; straight or slightly concave distal edges. Mesial cusplets apico-distally directed (with possible exception for first antero-lateral file) with concave distal cutting edge. Basal borderline of crown markedly convex. Root medially much higher than acrocone.
