Description
Original diagnose after Guinot et al. (2014) p. 71 [20107]: Minute-sized teeth not exceeding 700 mm in size showing a gradient monognathic heterodonty. Teeth broader than high except in anterior files. Crown high with erect main cusp and lateral cusplets lingually oriented. Cusps short to absent in laterals and posteriors, respectively. Labial crown face strongly ornamented by discontinuous ridges following the outline of the cutting edges. Additional short vertical ridges below main ornamentation. Short and wide apron overhanging the root labially. High triangular median uvula with pointed basal edge displaced mesially in laterals. High hemiaulacorhize root with depressed labial region and flared basal face. Wide medio-central foramen displaced mesially in laterals and large centro-basal foramen. Additional foramina in laterals.
