Description
Original diagnose after Cappetta et al. (2014) p. 3 [21747]: Species characterized by its rather labio-lingually compressed teeth and being able to reach a relatively large size (up to about 25 mm total width). Cutting edges with strong serrations secondarily serrated; root high; cusp with acute apex less than 90°; distal notch absent on the anterior and antero-lateral teeth but present on lateral and very lateral ones. Presence of a flatness of the root at the site of the lingual protuberance; labial face of the crown with a barely significant basal bulge.
