Population:

Morelet (1860:199) states that this species is common under stones on all islands and Backhuys (1975:95) that it is one of the most common land molluscs in the archipelago. Although the group is presently under revision, this appears to be the case; the material collected on Corvo needs deeper study, but it is provisionally assumed as L. fasciolata. This species is abundant throughout the islands in dry environments as in forested areas, preferentially near the sea. In Pico island it was found from 10 m to about 550 m (Martins et al. 2006), but Backhuys (1975: 94) reported it from 915 m, on Flores island. This currently widespread species is most probably a complex, so its representation on the various maps is mostly circumscribed to the typical specimens, and may not reflect the true extent of the taxon

Habitat and Ecology

L.fasciolata lives in forested habitats, where it can be found under dead leafs, as well as under heaps of rocks and stone walls, from xeric, littoral habitats, e.g. Ilhéu de Vila Franca do Campo (Martins 1995), to the endemic forest, e.g. Lagoa Seca, Flores island (Backhuys 1957: 94). It is very common under rocks, mainly at lower altitudes; in forests it can also be found on the underside of the leafs of live Hedychium gardneranum, but more commonly hiding in the curled, dry leafs of that same plant.

Major Threat(s):

Due to its wide range of habitats, no threats are foreseen.

Conservation Actions

More research is needed on the taxonomy.
