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. DistributionThis species is endemic to France.[1][2] References1. ^1 {{cite journal | author = Prie, V. | title = Belgrandia varica | journal = The IUCN Red List of Threatened Species | volume = 2010 | page = e.T155668A4818436 | publisher = IUCN | date = 2010 | url = http://www.iucnredlist.org/details/155668/0 | doi = 10.2305/IUCN.UK.2010-4.RLTS.T155668A4818436.en | access-date = 10 November 2017}} 2. ^1 Fontaine B., Bouchet P., Van Achterberg K., Alonso-Zarazaga M.
