Description
Original diagnose after Cicimurri et al. (2022) p. 5 [30628]: Diminutive teeth measuring just over 1 mm in total height and 1 mm in crown width. Two morphotypes occur, including one with robust longitudinal ridges on the labial and lingual faces, and one exhibiting longitudinal ridges on the lingual face but having a smooth labial face. When present, labial ridges extend from one-third to three-quarters of the crown height. Lingual ridges always extend nearly to the apex of the main cusp. Cusplets are small or may be lacking altogether. valid after Cicimurri et al. (2022) p. 5 [30628];
