The teeth are usually fairly small. Upper teeth have wide, coarsely serrated enamel shoulders. The main cusp is triangular, moderately inclined and finely serrated. Where the enamel shoulder meets the main cusp the abrupt change in direction and serrations creates a distinctive notch on each side.
Lower teeth are fairly indistinct.
They lack a cutting edge until at least halfway up the blade before becoming finely serrated. Largest tooth illustrated measures 16mm slant by 16mm wide.
