Description
Original diagnosis after Derycke & Goujet, 2011 [13583]: As for genus: Crown with three diverging main cusps, the middle one being shorter than the two diverging lateral ones, intermediate cusplets in a more labial position than the main ones, rugose base oriented lingually. Scales with a fl at base, a high neck and ridges on the crown, histological structure with an extensive network of wide vascular canals through the neck and base, box-in-box pattern, pallial dentine and mesodentine.
