Cochliopidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.

Paludestrina d'Orbigny, 1840 is an archaic synonym,[1] and has been placed on the Official Index of Rejected and Invalid Names by ICZN Opinion 2202.[2]

This family is in the superfamily Truncatelloidea and in the order Littorinimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

## Description[edit]

Cochliopidae snails are characterized by sharp, elongated spire-like structures, and can be found in rivers or brackish water.[1]

## 2005 taxonomy[edit]

The family Cochliopidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[3]

* Cochliopinae Tryon, 1866 \- synonyms: Mexithaumatinae D. W. Taylor, 1966, Paludiscalinae D. W. Taylor, 1966
* Littoridininae Thiele, 1928
* Semisalsinae Guiusti & Pezzoli, 1980 \- synonym: Heleobiini Bernasconi, 1991

## Genera[edit]

Liu et al. (2001)[4] have recognized 34 genera with more than 260 species within the subfamily Cochliopinae.[4]
