Porównanie

Price and Korn have chosen the neotype for the type species of Progonioclymenia, P. acuticostata (Münster, 1842) with juvenile ventrolateral spines and ribbing similar to those in the gonioclymeniids. This makes it fundamentally different from Clymenia aegoceras Frech, 1902, believed to be a junior synonym of P. acuticostata Bogoslovsky,1981. It is here transferred to Soliclymenia as the earliest member of the lineage. The specimen from the Prolobites-Platyclymenia Zone of the Ishikay River determined as S. solarioides Bogoslovsky,1981 has been made the type of Borisiclymenia ishikayensis  Korn and Klug, 2002, whereas that from the Clymenia-Gonioclymenia Zone of the Kia River section originally referred to P. acuticostata has been named P. bogoslovskyi. They may represent the same lineage.
