Neomphaloidea is a superfamily of deep-sea snails or limpets, marine gastropod mollusks previously regarded as in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005), but now classified in its own clade the Neomphalina. They are commonly known as "hydrothermal vent limpets".
The other superfamily of hydrothermal vent limpets is the Lepetodriloidea.
The anatomical characters of the Neomphaloidea largely follow the patterns as in the Vetigastropoda. But unusual morphological and phylogentic characters suggest a different systematic position and place it in its own clade, the Neomphalina.
The clade Neomphalina is, based on optimal phylogenetic analysis, deemed monophyletic [2]
