Cylindrobulla is a genus of sea snails or bubble snails, marine gastropod mollusks in the clade Sacoglossa.^[1]

Cylindrobulla is the type genus of the family Cylindrobullidae^[4] and it is the only genus in the family.^{[citation needed]}

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)^[5] as a sister group of Sacoglossa and placed it in the new order Cylindrobullacea.

1998 taxonomy

Mikkelsen (1998)^[6] has argued that the genus Cylindrobulla actually belongs in Oxynoacea within shelled Sacoglossa.^[6] 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.^[6]

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 infomal group Opisthobranchia.^[4]

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

2010 taxonomy

Molecular phylogeny analysis by Maeda et al. (2010)^[1] have confirmed placement of Cylindrobulla within Sacoglossa.^[1]
