2005 taxonomy

Architectibranchia was not used in the taxonomy by Bouchet & Rocroi (2005) and this taxon name has been listed as an available name.

2009 taxonomy

Clade Architectibranchia was reinstated by Malaquias et al. in 2009;Malaquias M. A. E., Dodds J. M., Bouchet P. & Reid D. G. (2009). "A molecular phylogeny of the Cephalaspidea sensu lato (Gastropoda: Euthyneura): Architectibranchia redefined and Runcinacea reinstated". '' Zoologica Scripta'' 38(1): 23-41. . they limited the taxon to Acteonoidea and Ringiculoidea. There are five families within the clade Architectibranchia: *

2010 taxonomy

Taxon Architectibranchia is not explicitly mentioned in the molecular analysis by Jörger et al. (2010).Jörger K. M., Stöger I., Kano Y., Fukuda H., Knebelsberger T. & Schrödl M. (2010). "On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia". '' BMC Evolutionary Biology'' 10: 323. . However, some of its members were included: Acteonoidea was moved to Lower Heterobranchia.
