Description
Original diagnosis after Ginter & Ivanov, 1992 [3129]: The crown consists of five cusps. Three main cusps are strongly inclined linguad and form large angles between each other. The labial face of central and of two smaller intermediate cusps Is covered by strong, subparallel ridges. The sculpture of the main lateral cusps is spirally curved. The base is thick, advanced far linguad; its linguo-lateral angles may be expanded linguad farther than its median part. The underside of the base forms an almost semicylindrical arch. A broad oval button occurs on the upper side.
