This doubtful taxon, described by Bernasconi, has never been found again despite recent researches in the type locality in Corsica (see Bertrand 2004). Initially described as Moitessieria corsica, Falkner et al. 2002 have placed the species in the genus Spiralix. Then, Boeters & Falkner (2009) have studied the type specimen again and propose to place the species within a new genus, the genus Corseria.

In 1996 this species was assessed as Vulnerable (VU D2) based on its restricted range and potential threats. This species' group is cryptic, as they live in subterranean ground-waters which are difficult to sample effectively and may well be rare. It has not been found again despite several surveys over the last 10 years. The species was not listed by Regnier et al. (2009) as an Extinct or Possibly Extinct species, and so on a precautionary basis the species is assessed as Critically Endangered (Possibly Extinct) B1ab(iii,v), based on a single known site, where the species has not been observed for 16 years, in order to flag the site as one requiring conservation action.

Spiralix corsica was originally described from France, based on records from a single site on Corsica. Its distribution is doubtful as it has not been found again since and further research is required to confirm the presence of the species is maintained at the reported location.

There is no population trend data available for this species.

This species lives in subterranean waters.

Subterranean habitats are vulnerable to water pollution from domestic (sewage and run-off) or agricultural (nutrient loads, herbicide and pesticides) sources. Falls in the water levels in the aquifer degrading the habitat maybe another threat if the aquifers are overexploited.

No trade in this species.

There is no conservation actions for this species. More research is needed on the taxonomy, population size, distribution and threats of this species.
