''Cylindrobulla'' is the type genus of the family Cylindrobullidae
and it is the only genus in the family.
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
Sacoglossa
Sacoglossa, commonly known as the sacoglossans or the "solar-powered sea slugs", are a superorder of small sea slugs and sea snails, marine gastropod mollusks that belong to the clade Heterobranchia. Sacoglossans live by ingesting the cellular co ...
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.
