Description
Original diagnose after Guinot et al. (2013) p. 610 [24889]: Small teeth (up to 1.5 mm wide); erect triangular main cusp with a pair of low and diverging lateral cusplets. Apron bifid, varying in morphology; strongly concave median region of the lingual face in profile view; well-developed triangular lingual protuberance with rounded extremity nearly reaching the lingual root edge. Abrupt marginolingual faces with characteristic depression in the basal region, from the base of the lingual protuberance to the marginal angles. Root heart-shaped with concave marginolingual and mediolabial edges and well-developed lingual protuberance. Broad central and marginolingual foramina. Slight occasional ornamentation of the labial crown face with short vertical and/or sub-horizontal ridges. Lateral and posterior teeth labiolingually compressed with reduced main cusp inclined to the posterior; small to absent anterior cusplet.
