Taxonomy

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''.

1996 taxonomy

It was treated by Jensen (1996) as a sister group of

and placed it in the new order Cylindrobullacea.

1998 taxonomy

Mikkelsen (1998) has argued that the genus ''Cylindrobulla'' actually belongs in Oxynoacea within shelled

. 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.

2005 taxonomy

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