Carychiinae
Carychiinae is a taxonomic subfamily of minute air-breathing land snails, terrestrial pulmonate gastropod mollusks.
Taxonomy
Carychiinae is part of the family Ellobiidae.
Some authors consider Carychiidae as a separate family.
Genera
Genera within the subfamily Carychiinae include:Carychiella Strauch, 1977Carychiopsina Kadolsky, 2020 †Carychiopsis Sandberger, 1872 †Carychium O. F. Müller, 1773 - type genus of the subfamily CarychiinaeKoreozospeum Jochum, Prozorova, Sharyi-ool & Páll-Gergely, 2015 Ovicarychium Kadolsky, 2020 †Turricarychium Kadolsky, 2020 †Zospeum Bourguignat, 1856 Zuella Kadolsky, 2020 †
Ecology
One lineage of the Ellobioidea, the Carychiidae has successfully accomplished a complete transition onto land. Extant carychiid snails inhabit aphotic and permanently wet epigean or subterranean environments throughout their Holarctic distribution. This dramatic shift from a marine to a terrestrial habitat has occurred independently of the stylommatophoran land-snails of the Eupulmonata.
