Belgrandia varica is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusc or micromollusc in the family Hydrobiidae.

Belgrandia varica was previously considered to be extinct,[2] however it has been classified as Critically Endangered (Possibly Extinct) by IUCN because it might still be present in a small spring that has been overlooked during previous surveys.

Distribution

This species is endemic to France.[1][2]
