Description
Original diagnosis after Underwood, Goswami, Prasad, Verma & Flynn, 2011 [13074]: In addition to generic diagnosis (above), lower lateral teeth moderately large (seen 13 to 19 mm wide) with up to six differentiated cusps. Cusps are all of similar shape and orientation and decrease in size distally, with the mesial (largest) cusp lower than root. In wider and lower teeth (maximum height half width), cusps are more broadly triangular than in narrower teeth. Mesial edge of root of all teeth, other than presumed first lower tooth, is gently convex. Mesial edge of first cusp straight or faintly convex, with six to nine serrations present on the lower half. Upper lateral teeth unknown.
