The talonid is simple and strongly joined to the posterior loph via the posterior accessory cusp. There are cingular remnants in the ends of the buccal valleys. The overall morphology of this tooth resembles that seen in bunodont listriodonts from Europe and Africa. The length and estimated breadth of at the base of the crown are 32-8 and 19-5 mm respectively. is a right M3 lacking only the roots and small fragments of enamel at the cervix level. Its enamel is thicker than is usually found in L. splendens and the tooth is more bunodont and lower-crowned, while the lophs are less well formed than in L. pentapotamiae. The 'furchen' are not clear, because they have apparently been eradicated by wear which has advanced to the stage where dentine is exposed on the two lingual cusps. The talon is simple and the lingual flare is marked. The length and breadth of are 25-9 and 220 mm respectively. Discussion. These two teeth probably belong to the same taxon, a bunodont listriodont close to Listriodon lockharti (Pomel, 1848) or L. akatikubas Wilkinson 1976. Teeth like these have.
