It is unknown whether this overlooked species is still present on offshore islets. The threats and population size and trend are unknown. Therefore this species is considered as Data Deficient (DD).
This species is endemic to the Madeiran island. It is found on the Ilheu dos Embarcadores off the Pta da Sao Lourenco, East Madeira (Seddon 2008). Groh (pers. comm., 2010) has recorded two fresh shells from the peninsula but the origin is uncertain. Quaternary fossils from deposits at Canical on the Pta da Sao Lourenco are abundant.
It is unknown whether the species is still present on offshore islets, where it was last recorded in 1896, but Groh recorded two fresh-looking shells from the mainland, although their origin is uncertain, as these could have been transported by gulls.
The habitat is nknown, but likely to be rocks within grassland and rocky slopes.
The main threats are unknown, as the status on these islets is uncertain.
A survey on the offshore islets is required to determine whether this species is still extant.
