Description
Original diagnosis after Siverson, Lindgren, Newbrey, Cederström & Cook, 2015 [22014]: Anterior teeth equipped with slender cusp; straight, very slightly curved or moderately distally inclined. Outer margin of cusplets more-or-less vertical on upper anterior teeth. Root symmetrical in labial/lingual views on first upper and lower anterior teeth but asymmetrical in basal view with one lobe more compressed than the other. Lingual protuberance of root poorly demarcated in basal view in upper anterior teeth but highly protruding in profile view, overhanging the neck. Most upper lateroposterior teeth equipped with rounded cusplets, lacking distinct apex.
