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
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
2017 taxonomy
Williams et al. (2008)[4] have made further refinements to the taxonomy of Trochoidea. The revised taxonomy as defined by Bouchet et al. (2017) resulted in the following families.[5] The fossil families, tentatively included in this list, are based on Tracey et al. (1993) [6]
- Angariidae Gray, 1857

- Colloniidae Cossmann, 1917
- Conradiidae Golikov & Starobogatov, 1987
- † Elasmonematidae Knight, 1956
- † Epulotrochidae Gründel, Keupp & Lang, 2017
- † Eucochlidae Bandel, 2002
- Liotiidae Gray, 1850
- Margaritidae Thiele, 1924
- †Metriomphalidae Gründel, Keupp & Lang, 2017
- † Microdomatidae Wenz, 1938
- †Nododelphinulidae Cox, 1960
- Phasianellidae Swainson, 1840
- † Proconulidae Cox, 1960
- † Sclarotrardidae Gründel, Keupp & Lang, 2017
- Skeneidae Clark W., 1851
- Solariellidae Powell, 1951
- Tegulidae Kuroda, Habe & Oyama, 1971
- Trochidae Rafinesque, 1815
- Turbinidae Rafinesque, 1815
- † Tychobraheidae Horný, 1992
- † Velainellidae Vasseur, 1880
Unassigned to a family:
- Margarella Thiele, 1893 - Margarella rosea belongs to Cantharidinae,[7] but Margarella antarctica belongs to Calliostomatidae/Thysanodontinae as Carinastele antarctica.[7]
