There are known about 60 freshwater species of Stenothyridae in the Palearctic (6 species), Oriental (about 60 species) and Australasian region (about 5 species)[2] and some marine. There are 19 endemic species of Stenothyridae in the Lower Mekong River flowing through Thailand, Laos and Cambodia.[2]
American malacologist George Washington Tryon firstly defined this taxon as Stenothyrinæ in 1866.[1] Tryon's diagnosis reads as follows:[1]
| “ |
Stenothyrinæ. Shell turbinate. Operculum subspiral, calcareous. Distribution Indian. Stenothyra, Gabbia. |
” |
Genus Gabbia is classified in Bithyniidae nowadays.
Genera within the family Stenothyridae include:
The habitat of Stenothyridae include rivers, streams and estuaries.[2] Stenothyridae invaded freshwater habitats from marine ones in at least one independent lineage.[2] Some species of Stenothyridae are euryhaline and/or marine.[2] Probably there are some amphidromous (migrate from freshwater to the sea) species of Stenothyridae.[2]
