Tryon, 1866[1]
Diversity[2]
About 60 freshwater species

This family has no subfamilies.[3]

Distribution

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]

Description

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.

Currently the genus Gabbia is classified within the family Bithyniidae.

Genera

Genera within the family Stenothyridae include:

  • Farsithyra Glöer & Pešić, 2009[4]
  • Gangetia Ancey, 1890[5]
  • Stenothyra Benson, 1856 - type genus of the family Stenothyridae[3]

Ecology

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]
