Te element is arched in lateral view. In oral view, the margins of the thickened platform are subparallel at mid-length, and taper anteriorly. Te platform is V-shaped, and the margin is directed orally. Te cusp may be conspicuous in well preserved specimens. A posterior process may be present, which bears additional posterior denticles, otherwise the posterior margin is rounded. Te carina denticles are partly fused at mid-length, taller and more discrete towards the anterior end.
