|Taxonomic Notes:||In literature this species was often placed under the genus Erinna which is found in Hawaii in similar habitat. However, this is a case of convergence and not relationship.|
|Red List Category & Criteria:||Critically Endangered (Possibly Extinct) B2ab(iii) ver 3.1|

|Reviewer(s):||Cumberlidge, N., Ranaivoson, C.H., Randrianasolo, H. & Rasamy, J.|
The species was rediscovered in 1992, after 100 years, but the area of occupancy (AOO) is still very limited as it occurs only at one locality. Invasive plant species are thought to be altering the specific habitat (mosses) that this species is believed to require and based on this threat, there is a single location. This threat is also leading to a continuing decline in habitat quality. It is therefore considered to be Critically Endangered as in the previous assessment (Brown and Griffiths 1996). The species is not cited in the latest records on the Réunion malacofauna (Forcellini 2011, Jay 2016) and it is thought to be Possibly Extinct.
|Date last seen:||1992|
|Previously published Red List assessments:|
|Range Description:||This species is only known from a waterfall at or near the type locality on Réunion (Brown 1994, Brown and Griffiths 1996). The species is not cited in the latest records on the Réunion malacofauna (Forcellini et al. 2011, Jay 2016).|

|Population:||This species was thought to have become extinct and was rediscovered at or near the type locality by O. Griffiths in 1992.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This is a small limpet-like gastropod adapted for clinging to rocks in mountain streams between 1,200-1,300 m asl (Brown 1994). It is found in mosses according to the original description.|
|Use and Trade:||This species is not used.|
|Major Threat(s):||No particular threats are confirmed. However, invasive plant species are thought to be altering the specific habitat (mosses) this species is thought to require.|
|Conservation Actions:||No conservation measures have been implemented or are planned.|
