Checked: verified by a taxonomic editorClassification Aculifera is a group, with rank of subphylum, including the Aplacophora (Caudofoveata and Solenogastres) and Polyplacophora (chitons), all other molluscs being included in subphylum Conchifera (shell-bearers)(Hatscheck in Blumrich, 1891; Scheltema, 1993) or alternately including only the Aplacophora, aside with the subphyla Placophora and Conchifera (Stasek, 1972).

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 phylogenetic relationship like (Solenogastres(Caudofoveata(Polyplacophora(Conchifera)))) making Aplacophora (and therefore Aculifera) paraphyletic.
Because groupings of molluscan classes into clades is highly controversial (for a review of competing hypothesis see Steiner & Dreyer (2003) Molecular phylogeny of Scaphopoda (Mollusca) inferred from 18S rDNA sequences: support for a Scaphopoda–Cephalopoda clade. — Zoologica Scripta, 32, 343–356), classes will be treated herein as an unresolved polytomy within Phylum Mollusca. [details]
