Later, I. Turculet divided Lamellaptychus into several subgenera. Within the framework of both the genera, species and subspecies were distinguished, which resulted in binominal and trinominal nomenclature. With regard to the richness of newly described species and subspecies in recent years, is not possible to continue using the original system. It is the basic ribbing that plays the decisive role in the generic and subgeneric classification of ribbed aptychi. In the case of subspecies systematics, all details on the valve surface are used with the exception of the sigmoidal bend (fractocostatus) and radial lines (radiatus). The ribbed aptychi are newly divided into the following families: Punctaptychidae fam. nov. and Lamellaptychidae fam. nov.
