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

Description

Three Seguenziid gastropods

The distinctive characteristics of the shells of the Seguenzioidea are:

Taxonomy

This superfamily was placed in part or in whole previously to 1979 either in the Archaeogastropoda near the superfamily Trochoidea or in the Caenogastropoda near the superfamily Stromboidea. 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". At about the same time in 1987 Goryachev elevated the superfamily to ordinal status Seguenziiformes in the superorder Littorinimorpha, based on the taenioglossal radula.

2005 taxonomy

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

Superfamily Seguenzioidea
Family Seguenziidae
Family Chilodontaidae
† Family Eucyclidae
† Family Laubellidae

2007–2009 taxonomy

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

The superfamily Seguenzioidea consists of six families:

Unassigned to a family
Unassigned genera brought into synonymy
