Pleuroceridae is a family of small to medium-sized freshwater snails, aquatic gilled gastropod mollusks in the superfamily Cerithioidea.These snails have an operculum and typically a robust high-spired shell.
Reproduction is iteroparous, and juvenile snails emerge from eggs laid on a firm surface by a gonochoristic female. There is no veliger stage.
Distribution
Species assigned to this family are widespread in temperate and tropical parts of Southern and Eastern Asia,[citation needed] Africa,[citation needed] and North and Central America. Most require unpolluted rivers and streams, but a few are adapted to living in lakes or reservoirs.
Taxonomy
2005 taxonomy
The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005):
- Pleurocerinae P. Fischer, 1885 - synonyms: Ceriphasiinae Gill, 1863; Strepomatidae Haldeman, 1864; Ellipstomatidae Hannibal, 1912; Gyrotominae Hannibal, 1912; Anaplocamidae Dall, 1921
- Semisulcospirinae Morrison, 1952 - synonym: Jugidae Starobogatov, Prozorova, Bogatov & Sayenko, 2004 (n.a.)
2009 taxonomy
Subfamily Semisulcospirinae within Pleuroceridae was elevated it its family level Semisulcospiridae by Strong & Köhler (2009).[2]
Genera
Genera within the family Pleuroceridae are organized in the one subfamily only since 2009 and they include:
Pleurocerinae
- Pleurocera
- Athearnia
- Elimia
- Gyrotoma
- Io Lea, 1831 - with the only species Io fluvialis (Say, 1825)
- Leptoxis
- Lithasia
