For more than a century Frustulia saxonica was considered to be an infraspecific variety of F. rhomboides. A search for the type of the basionym, Navicula rhomboides Ehrenberg, revealed that Navicula rhomboides is not a Frustulia. A lectotype is presented for N. rhomboides Ehrenberg. As a consequence twelve new nomenclatural transfers within the genus Frustulia have been proposed. From the original material of Frustulia saxonica Rabenhorst, type of the name of the genus, a lectotype is chosen from among the heteromorphic specimens which had been traditionally identified as F. rhomboides.
