Rissooidea, originally named Rissoacea by Grey, 1847, is a large taxonomic superfamily of small and minute saltwater, brackish water, freshwater, and semi-terrestrial snails which have gills and an operculum. The gastropod mollusks in this superfamily are mostly marine, but as can be seen from the following list, the superfamily also includes some freshwater, brackish water, and semi-terrestrial families and genera.
[edit] Families
Families within the superfamily Rissooidea include:
- Anabathridae, marine
- Assimineidae, semiterrestrial, also saltwater and freshwater
- Barleeiidae, marine
- Bithyniidae, freshwater
- Caecidae, marine
- Calopiidae, marine
- Cochliopidae, freshwater
- Elachisinidae, marine
- Emblandidae, marine (one species only)
- Epigridae, marine
- Falsicingulidae, marine
- Helicostoidae, freshwater (one species only)
- Hydrobiidae (including Amnicolidae, Istrianidae, Sadlerianidae), freshwater and brackish water
- Hydrococcidae, marine
- Iravadiidae, marine
- Lithoglyphidae, freshwater
- † Mesocochliopidae Yu, 1987, marine (fossil only)
- Moitessieriidae, freshwater
- † Palaeorissoinidae, marine (fossil only)
- Pomatiopsidae, freshwater
- Rissoidae, marine
- Stenothyridae, freshwater
- Tornidae, synonym Adeorbidae, marine
- Truncatellidae, semiterrestrial
[edit] Nomenclature
This superfamily was previously known as Rissoacea. Prior to the recent ruling by the ICZN, many invertebrate superfamily names ended in the suffix -acea, or -aceae, not -oidea as now required according the ICZN article 29.2. The suffix -oidea used to be used for some subclasses and superorders, where it is stll found. In much of the older literature including Keen 1958, Moore et al. 1952, and the Treatise on Invertebrate Paleontology, gastropod superfamilies are written with the suffix -acea.[1][2][3]
