Tryonia is a genus of freshwater snails in the family Hydrobiidae.Wesselingh F. P., et al. (2006). [http://www.repository.naturalis.nl/document/41346 Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia.] Scripta Geologica 1333 19-290. This genus is sometimes placed in the family Cochliopidae.Bouchet, P. (2014). Tryonia Stimpson, 1865. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=722774 on 2014-11-16
Snails of this genus are very small with narrow shells. Females brood young within the genital tract. Species usually live in springs. The genus is differentiated from others by the structure of the male and female reproductive systems.Hershler, R., et al. (2011). [http://www.mapress.com/zootaxa/2011/f/zt03001p032.pdf New species and records of springsnails (Caenogastropoda: Cochliopidae: Tryonia) from the Chihuahuan Desert (Mexico and United States), an imperiled biodiversity hotspot.] Zootaxa 3001 1-32.
Most of these snails occur in western North America, especially the Chihuahuan Desert. There are also species known in Florida and Guatemala.
