Description
Original diagnosis after Duffin & Ward, 2017 [25825]: Genus known only on the basis of isolated teeth measuring up to 1.3 mm labiolingually. The dentition is quite homodont, with crowns symmetrical to slightly asymmetrical in occlusal view. A single high cusp with almost circular cross-sectional shape and cutting edges is present labially. The labial cusp is separated from the lingual heel by a deep central trough. A prominent upright cusp, lower than the labial cusp, is present on the lingual heel. The cutting edge sweeps lingually forming a horizontal ridge which divides into five lingual cristae, labial examples of which are denticulate.
