There is a debate over whether Caudofoveata should be a subclass of a Class Aplacophora or a separate class. The phylogenetic relationships of aplacophoran molluscs are not unambiguously resolved although the data at hand (see Haszprunar 2000: American Malacological Bulletin 15, 115-130, and Glaubrecht, Maitas & Salvini-Plawen, 2005: Mitteilungen aus der Museum für Naturkunde in Berlin – Zoologische Reihe 81, 145-166) would support a relationship like Solenogastres(Caudofoveata(Polyplacophora(Conchifera)))) making Aplacophora paraphyletic. For this reason, contra the Aculiferan hypothesis of Scheltema (1993: Biological Bulletin 184, 57-78) and in agreement with the European school of Salvini-Plawen, Solenogastres and Caudofoveata are given full class status.
