M. Ubilla et al. 1994Very close to Leontinia but with 11 enlarged and caniniform, and I2 small. Lower incisors more procumbent and there are no lingual grooves on the protocones of P2-4 as there are in Leontinia. Deep lingual groove in the trigonid of m3, size of the lower canine intermediate between i3 and pl and shorter symphysial length in contrast to Leontinia.
