Description
Original diagnosis after Guinot, Hautier, Sambou & Martin, 2023 [31795]: Teeth broader than high not exceeding 0.8 mm wide. Crown lozenge-shaped in occlusal view; labial visor strongly overhanging the root with median labial expansion separated by straight to concave margino-labial edges. Marginal angles wide and bevelled labially. Transverse crest high, wide, and acute, separating the lingual and labial faces. Transverse crest straight to curved labially, tapering before reaching the margino-lingual edges, anterior to the marginal angles. Occlusal region flat and oval to triangular in shape. Lower lingual region abrupt, moderately developed and concave in profile view with flared basal edge. Median uvula short, wide and triangular, demarcated from margino-lingual faces by a slight concavity. Holaulacorhize root low and lingually positioned with concave lingual face and flat to convex and oblique labial face. Root lobes with triangular basal faces; wide nutritive groove with rounded central foramen positioned slightly labially.
