Cylindrobulla is a genus of sea snails or bubble snails, marine gastropod mollusks in the clade Sacoglossa.
Cylindrobulla is the type genus of the family Cylindrobullidae and it is the only genus in the family.
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) 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.
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 infomal group Opisthobranchia.
According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Cylindrobullidae has no subfamilies.
Molecular phylogeny analysis by Maeda et al. (2010) have confirmed placement of Cylindrobulla within Sacoglossa.
Species within the genus Cylindrobulla include:
