The body of this organism is egg-shaped and highly flattened from top to bottom. Its protective covering consists of two plates: the dorsal plate, which is either concave or nearly straight, pointed towards the rear, and notably smaller than the ventral plate, which is rounded at the rear and convex. The connection between the two plates forms a deep groove, dividing the body cavity into two unequal sections, with the larger portion located ventrally and containing most of the internal organs. The lateral edges of the plates are nearly parallel and somewhat raised. The creature’s foot is short and slender, lacking bristles on the second-to-last joint. Its toes are elongated, thin, cylindrical, with parallel sides and slightly enlarged bases. The head is sizable and linked to the front edge of the protective covering by a stiffened cuticular membrane. The face slopes downward. Its feeding apparatus, called the corona, follows a familial pattern. The grinding structure, known as the mastax, is of a modified malleate type, with each hook possessing ten or more long, slim teeth. The extensions called rami are triangular in shape and each carries a very small comb-like structure on their inner tips. Other internal structures resemble those of Euchlanis.
