Description
Original diagnose after Guinot et al. (2014) p. 67 [20107]: Teeth wider (up to 4 mm) than high showing a moderate degree of monognathic heterodonty. Triangular biconvex main cusp inclined lingually.Well-developed cutting edges in connection with lateral heels. Fairly high heels with more or less marked indentations. Convex labial face with marked labial protuberance of varying size, protruding labially and reaching the baseline of the root. Vertical or sub-vertical ridges commonly present on labial protuberance. Lingual protuberance elongate and inclined basally, nearly reaching the lingual root edge. Root hemiaulacorhize with sub-horizontal branches and strong lingual protuberance in anterior teeth. Presence of a medio-lingual, a wide central and numerous margino-lingual foramina.
