Description
Original diagnosis after Adnet, Cappetta, Guinot & Notarbartolo Di Sciara, 2012 [16825]: The teeth have a small size, less than 5 mm broad, with a roughly hexagonal outline in occlusal view. Marginolabial and marginolingual angles very obtuse and rounded. Occlusal face as developed or less developed than the complete width of the crown, and very hollowed transversally. Oblique and well-developed labial face covered by corrugated enameloid. Sharp and salient labial visor and well-marked lingual bulge at the base of the crown. Root as high as the crown, with about six lobes separated by rather deep and broad W-shaped furrows. Sharp basal face of the lobes. The two marginal lobes may be shorter and diverging more than the others.
