Assessment Rationale:

There is insufficient information on distribution, population size and trend and threats to assess this species. There are no published records since 1932. Consequently the species is assessed as Data Deficient (DD).

Geographic Range:

This species is endemic to Gran Canaria. It was described in 1839 and later given several synonyms by Mabille in 1882 and 1883. The last published reference is by Odhner (1932), who describes it to be not rare in the middle heights of Gran Canaria. The species was not refound or mentioned by Ibanez and his colleagues, nor found by K. Groh (K. Groh, pers. comm., 2011). Fresh shells are offered by shell dealers such as Femorale in Brazil and Shell Auction in Italy, so apparently living populations of this species still exist, but no data are available.
