Cette espèce se distingue facilement par le grand raccourcissement de la dernière molaire inférieure qui est à peine un peu plus longue que l'avant-dernière, et par son lobe postérieur qui est convexe sur le côté externe, sans vestige du sillon perpendiculaire qu'on voit sur la même dent des autres espèces.
