Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. [1] 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. [2]
Note that this taxon is not the same as a pulmonate land snail genus which is spelled the same way: Trochoidea (genus).
Taxonomy
2005 taxonomy
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
According to Williams et al. (2008)[3] 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,[4] but Margarella antarctica belongs to Calliostomatidae/Thysanodontinae as Carinastele antarctica.[4]
- 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
