Description
Original diagnose after Feichtinger et al. (2020) p. 159 [29103]: Minute teeth with single cusp, not exceeding 1 mm in height. Irregular cutting edges not reaching the base of the cusp. Crown constricts from apex to base at two thirds of height of cusp, resulting in a spearhead-shaped crown morphology. Crown ending basally with basal collar as typical for genus. Labial crown face smooth with occasional enameloid protuberances situated near crown neck, where the cusp narrows. Lingual crown face strongly convex. Bi- or trilobate root with numerous, small foraminal openings piercing the tooth base.
