Description
Original diagnose after Duffin & Batchelor, 2025 [34256]: Species known from isolated teeth characterised by the following combination of characters: the root is equal to the crown in length; the central cusp is moderately high and robust; the apron extends to the labial base of the crown and has parallel-sided to tapering margins with a rounded to occasionally squared off terminus; the apron is surmounted by a prominent keel which extends half way up the central cusp; a horizontal ridge runs the greater part of the length of the crown labially, with short vertical ridges attaining the crest of the crown shoulder; the lateral heels are deep (subequal to the depth of the root), occasionally inflated centrally and downturned. The basal face of the holaulacorhize root is concave.
