. This species is very well distinguished by its first lower premolar that has the morphology of a well-developed canine, being anteriorly and posteriorly isolated by rather long diastemata. The lower canine is incisor-shaped, anteriorly leaned on the external incisor. The second lower premolar is elliptical, without internal perpendicular groove; no trace of external groove is visible.
