Description
Original diagnose after Duffin & Batchelor, 2025 [34256]: Species founded on isolated asymmetrical multicuspid teeth showing the following combination of characters. Crown ornament is usually better developed on the lingual face of the crown than the labial face. A wavy horizontal ridge runs from end to end of the crown on top of the labial crown shoulder, giving rise to both short and longer vertical ridges apically and a reticulate network of ridges basally. The basal margin of the labial face of the crown overhangs the crown/root junction. The root vascularisation is pseudopolyaulacorhize. The root is longer than the crown, mesiodistally, with upturned lateral extremities. Anterior teeth have a slightly distally inclined central cusp, which may be flanked by lateral cusplets (usually one pair) both mesially and distally. The central cusp is biconvex, not flattened labio-lingually; ornament is usually restricted to the mesial and distal flanks of the central cusp, the lateral cusplets and the basal regions of the crown. The root has a lingual protuberance and a U-shaped outline to the basal face. In antero-lateral and lateral teeth, the distal inclination of the central cusp increases to around 30 °, lateral cusplets are retained distally but the mesial heel is surmounted by an elongate crenulated cutting edge, which may encroach on the mesial cutting edge of the central cusp. The root in these teeth is more elongate and less U-shaped than is the case with anteriors. Posterior teeth are the most heavily ornamented.
