Carychiinae
# Carychiinae

Carychiinae is a taxonomic subfamily of minute air-breathing land snails, terrestrial pulmonate gastropod mollusks.

## Taxonomy

Carychiinae is part of the family Ellobiidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Some authors consider Carychiidae as a separate family.

## Genera

Genera within the subfamily Carychiinae include:

* Carychiella Strauch, 1977
* Carychiopsina Kadolsky, 2020 †
* Carychiopsis Sandberger, 1872 †
* Carychium O. F. Müller, 1773 - type genus of the subfamily Carychiinae
* Koreozospeum 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 (Carychium) or subterranean (Zospeum) 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.
