Description
Original diagnose after Duffin & Batchelor, 2025 [34256]: Species known from isolated teeth characterised by the following combination of characters: the root is wider than the crown; the central cusp is relatively high and slender; the unornamented apron extends well beyond the labial base of the crown, has tapered sides and a round to slightly squared terminus; the mesial and distal heels are shallow (one third to one quarter the height of the root), downturned in anterior teeth but more horizontal in laterals, with crests that may be straight, slightly inflated centrally or developed into rudimentary incipient cusplets; the basal face of the root is flat to slightly arched with holaulacorhize vascularisation.
