 The accessory ridges on the upper molars, the anterolophs and mesolophs, are less well-developed than in "T. hylophilus".The third upper molar is reduced relative to the second, much more so than in "T. hylophilus".The lower molars are generally similar to the uppers, but the anteroconid (the equivalent of the anterocone on the first lower molar) is often undivided and the third molar is unreduced.
