Pomatiopsidae is a family of small, mainly freshwater snails, (some also occur in other habitats) that have gills and an operculum, aquatic gastropod mollusks in the superfamily Rissooidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Contents

Pomatiopsidae are well known as intermediate hosts of Asian schistosomes.

Distribution

Species in the family Pomatiopsidae occur worldwide. The generic diversity of Pomatiopsinae is particularly high in the Japanese Archipelago, where four of the eight genera, including two endemics, are recorded. The subfamily Triculinae radiated as aquatic snails in freshwater habitats in Southeast Asia.

Description

The American malacologist William Stimpson first defined this taxon as Pomatiopsinae in 1865. Stimpson's diagnosis reads as follows:

Subfamilies

The family Pomatiopsidae consists of 2 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005) that follows classification by Davis (1979):

  • Ecology

    The Pomatiopsidae have various life habits: aquatic, amphibious, littoral, halophilic, cavernicolous and even terrestrial. Terrestrial taxa occur only on the Japanese Archipelago located in East Asia (Blanfordia). Tomichia and Coxiella include several halophilic species occurring on saline lakes.

    Pomatiopsidae invaded freshwater habitats from marine ones in one or in two independent lineages. They also invaded terrestrial habitats from freshwater habitats in two independent lineages.
