Description
Original diagnosis after Underwood & Cumbaa, 2010 [12632]: Teeth small, under 2 mm in greatest dimension, showing moderate heterodonty. Tooth crown of similar width to height. All teeth close to symmetrical, with a robust and conical main cusp (less than 1.5 times as high as wide) flanked by a single pair of short and robust lateral cusplets, with a second pair of incipient cusplets sometimes being present. A single ridge forming a sharp-edged keel is present on the labial face, and extends from half way up the main cusp to the base of a narrow but very prominent labial boss, sometimes bifurcating near the base. Other, shorter, ridges are present elsewhere on the crown but are always widely spaced and never join. Lingual crown face strongly convex with a very well-developed lingual protuberance at the base. Other than the labial boss, the crown does not strongly overhang the root. The root is wider and deeper than the crown, with a very well-developed nutritive groove seen in all teeth. The distal parts of the root lobes are somewhat recurved labially and have flared bases.
