Cylindrobulla

The suborder Cylindrobulloidea used to be recognized as monogeneric suborder; in other words there was only one family in the suborder, the family Cylindrobullidae, and only one genus Cylindrobulla.

It was treated by Jensen (1996){{cite journal | author=Jensen, K.R.| title=Phylogenetic Systematics and classification of the sacoglossa (Mollusca, Gastropoda, Opisthobranchia)| journal=Philosophical Transactions of the Royal Society| year=1996| volume=351| pages=91–122| doi=10.1098/rstb.1996.0006}} as a sister group of Sacoglossa and placed it in the new order Cylindrobullacea.

Mikkelsen (1998) has argued that the genus Cylindrobulla actually belongs in Oxynoacea within shelled Sacoglossa. This change in taxonomy was suggested on the basis of the similarity in many characteristics: digestive, sexual, pallial (= concerning the mantle), and the nervous system.{{cite journal | author=Paula M. Mikkelsen| title=Cylindrobulla and Ascobulla in the western Atlantic (Gastropoda, Opisthobranchia, Sacoglossa): Systematic review, description of a new species, and phylogenetic reanalysis| journal=Zoologica Scripta| year=1998| volume=27| issue=1| pages=49–71| doi=10.1111/j.1463-6409.1998.tb00428.x}}

According to the taxonomy by Bouchet & Rocroi (2005), is the Cylindrobullidae the only family in the superfamily Cylindrobulloidea and Cylindrobulloidea is the only superfamily within the group Cylindrobullida in the informal group Opisthobranchia.{{Bouchet 2005}}

According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Cylindrobullidae has no subfamilies.
