Description
Original diagnosis after Ivanov, 2013 [19847]: Multicuspid teeth, elongated mesio-distally; crown strongly inclined lingually, flattened labio-lingually, includes seven to eleven cusps, with wide, triangular central, moderate outer intermediate, short inner intermediate and lateral cusps; cusps separated from each other, slightly fused basally, divergent and form a fan-like structure, with distinct lateral carina; lateral cusps strongly inclined distally; labial ornamentation comprises two long cristae forming a lanceolate patten, and intervening short cristae; base arched and lingually shortly extended, with occlusal thickening, longitudinal groove, shallow labial depression and delicate labio-basal projection; one or two larger foramina in the middle of lingual rim, two to four foramina in the center of basal surface.
