Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum.^[2] Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.^[3]

This taxon is not the same as a pulmonate land snail genus which is spelled the same way: Trochoidea (genus).

Taxonomy[edit]

2005 taxonomy[edit]

This superfamily consisted of nine following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

Trochidae Rafinesque, 1815

Calliostomatidae Thiele, 1924 (1847)

† Elasmonematidae Knight, 1956

† Eucochlidae Bandel, 2002

† Microdomatidae Wenz, 1938

† Proconulidae Cox, 1960

Solariellidae Powell, 1951 - synonym: Minoliinae Kuroda, Habe & Oyama, 1971

† Tychobraheidae Horný, 1992

† Velainellidae Vasseur, 1880

2008 taxonomy[edit]

According to Williams et al. (2008)^[4] the taxonomy of Trochoidea looks this:

Calliostomatidae Thiele, 1924 (1847)

Liotiidae Gray, 1850

Margaritidae Thiele, 1924

Skeneidae Clark W., 1851

Solariellidae Powell, 1951

Tegulidae Kuroda, Habe & Oyama, 1971

Trochidae Rafinesque, 1815

Turbinidae Rafinesque, 1815

† Elasmonematidae

† Eucochlidae

† Microdomatidae

† Proconulidae

† Tychobraheidae

† Velainellidae

Unassigned to a family:

Margarella Thiele, 1893 - Margarella rosea belongs to Cantharidinae,^[5] but Margarella antarctica belongs to Calliostomatidae/Thysanodontinae as Carinastele antarctica.^[5]

Families brought into synonymy

Cyclostrematidae P. Fischer, 1865: synonym of Liotiidae Gray, 1850

Gazidae Hickman & McLean, 1990: synonym of Margaritidae Thiele, 1924

Stomatellidae Gray, 1840: synonym of Stomatellinae Gray, 1840

Stomatiidae Carpenter, 1861: synonym of Stomatellinae Gray, 1840
