Amnicolidae is a family of small freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the superfamily Rissooidea.

This family is in the clade Littorinimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family was previously considered to be a subfamily of Hydrobiidae.


The family Amnicolidae consists of 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[2]


Genera in the family Amnicolidae include:

subfamily Amnicolinae

subfamily Baicaliinae

  • Baicalia Martens, 1876 - type genus of the subfamily Baicaliinae
  • Maackia Clessin, 1880[7]

subfamily Emmericiinae Brusina, 1870

  • Emmericia Brusina, 1870 - type genus of the subfamily Emmericiinae
