Taxonomy

edit

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.[5] 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".[6] At about the same time in 1987 Goryachev elevated the superfamily to ordinal status Seguenziiformes in the superorder Littorinimorpha, based on the taenioglossal radula.[7]

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 Chilodontaidae
† Family Eucyclidae
† Family Laubellidae

2007–2009 taxonomy

edit

Kano et al. (2009)[8] elevated the subfamily Calliotropinae to the family level as the Calliotropidae, and the subfamily Cataeginae to family level as the Cataegidae.[8]

The superfamily Seguenzioidea consists of six families:[9]
