Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda. [1] [2]

Description[edit]

The distinctive characteristics of the shells of the Seguenzioidea are:

Taxonomy[edit]

This superfamily was placed in part or in whole previously to 1979 in either in the Archaeogastropoda near the superfamily Trochoidea or in the Caenogastropoda near the superfamily Stromboidea [4] In 1987 Salvini-Plawén and Haszprunar changed its status to the suborder Seguenziina, based on the radular formula that they considered to be intermediate between "rhipidoglossate" and "taenioglossate". [5] At about the same time in 1987 Goryachev elevated the superfamily to ordinal status Seguenziiformes in the superorder Littorinimorpha, based on the taenioglossal radula. [6]

2005 taxonomy[edit]

2005 taxonomy according to Bouchet & Rocroi, 2005. (Families that are exclusively fossil are indicated with a dagger †.)

Superfamily Seguenzioidea
Family Seguenziidae
Family Chilodontidae
† Family Eucyclidae
† Family Laubellidae

2007-2009 taxonomy[edit]

Kano et al. (2009)[7] elevated the subfamily Calliotropinae to the family level as the Calliotropidae, and the subfamily Cataeginae to family level as the Cataegidae.[7]

The superfamily Seguenzioidea consists of four families: [8]

Unassigned genera brought into synonymy
