Chilina is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the superfamily Chilinoidea.
Chilina is the only genus in the family Chilinidae.
Distribution
Chilinidae occupies the temperate and cold zones of South America from the Tropic of Capricorn to Cape Horn and Falkland Islands. Distribution of Chilina include Argentina (17 species, 12 of them are endemic), Uruguay (2 species), Brazil (about 4 species).
Taxonomy
The family Chilinidae has been classified in the clade Hygrophila within the informal group Basommatophora (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). There are no subfamilies.

Ecology
Within their area, the Chilinidae are abundant snails in all suitable stations, as Physidae are in North America. They swarm in springs, small streams, lakes, and in some places the margins of rivers. They are most abundant southward, becoming rarer and local toward the northern borders of their range.
Chilina gibbosa and Chilina fluminea are medically important, because they transfer parasites causing dermatitis.
