Overview
Pomatiopsidae is a family of small mainly freshwater snails (but also in other habitats) with gills and an operculum, aquatic gastropod mollusks in the superfamily Rissooidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Pomatiopsidae are well known as intermediate hosts of Asian schistosomes.3]
Distribution
Pomatiopsinae are distributed worldwide.[3] The generic diversity of Pomatiopsinae is particularly high in the Japanese Archipelago, where four of the eight genera including two endemics, are recorded.[3] Triculinae radiated as aquatic snails in freshwater habitats in Southeast Asia.[3]
Description
American malacologist William Stimpson firstly defined this taxon as Pomatiopsinae in 1865.[1] Stimpson's diagnosis reads as follows:[1]
Subfamilies
The family Pomatiopsidae consists of 2 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005)[6] that follows classification by Davis (1979):[7]
- subfamily Pomatiopsinae Stimpson, 1865 - synonyms: Hemibiinae Heude, 1890; Tomichiinae Wenz, 1938;[8] Coxiellidae Iredale, 1943;[9] Oncomelaniidae Salisbury & Edwards, 1961; Cecininae Starobogatov, 1983
- subfamily Triculinae Annandale, 1924[10]
Family-group name Rehderiellinae Brandt, 1974[13] is also in Pomatiopsidae, but it is not allocated in detail.[6]

Ecology
Pomatiopsidae possesses various lifestyles from aquatic to amphibious, littoral, halophilic, and even terrestrial.[3] Terrestrial taxa occur only on the Japanese Archipelago located in East Asia (Blanfordia).[3] Tomichia and Coxiella include several halophilic species occurring on saline lakes.[3]
Pomatiopsidae invaded freshwater habitats from marine ones in one or in tw o independent lineages.[2] Additionally they invaded terrestrial habitats from freshwater habitats in two independent lineages.[3]
