Gatunek typowy Ambalodus elegans RHODES, 1953. Opis
Diagnosis - A weakly developed platform (with variably developed accessory lobes) in the sp and oz elements . The symmetry transition series similar to that in coeval species of Amorphognathus,but with strongly bent cusp in the ne elements. Remarks. - The platform elements of the genus are similar to those of Baltoniodus . Except for the symmetry transition series , which is distinctly balognathid, the most significant ifference concerns the position of branching of the anterior process in the platform elements . In Rhodesognathus, like other balognathids, it is connected with the external denticle of the cusp, while in Balt oniodus a rib connects the process directly with the cusp.
