Glacidorbis

Glacidorbis is a genus of minute freshwater snails with an operculum, aquatic gastropod molluscs or micromolluscs in the family Glacidorbidae.

This genus has proved to be somewhat enigmatic in terms of where it belongs within the taxonomy of the gastropods. It was previously thought to belong in the family Hydrobiidae or even in the Basommatophora.
