Description
Original diagnose after Siverson (1995) p. 977 [2215]: Basal face of root subrectangular and, with no observed exceptions (N = 30), hemiaulacorhizous. Central foramen generally with sharp edge and of same size or slightly larger than mediolingual foramen on lingual protuberance. Crown almost as high as wide in anterior files but progressively rela-tively wider towards commissure and twice as wide as high in posterior teeth. Cusp relatively upright in lateral teeth and well detached from heels.
