Central and S Switzerland, adjacent N Italy.
Type Locality: Switzerland: Canton Obwalden, Rischiwald near Glaubenberg, 1080 m.
External: Slug colour variable, creamy white, brownish or black, often with colour spots or bands; mantle always evenly coloured without patterns (difference to several other species).
Internal: Penis 1/3-1/2 of body length, inside with weak transverse folds and one interior pilaster; vas deferens inserts close to tip of penis, retractor attached at same point as vas deferens.
Up to 200 x 22 mm (preserved 165 x 17 mm).
Mountain habitats, usually at 1000-1500 m, also in forests.
Slugs feed on lichens growing on coniferous trees.
Life History and Behavior
Active at night, locally in high population densities.
Copulation takes place in 80-180 cm height above surface (for example at coniferous tree trunks), posterior ends of both animals are united and sticked on a slime thread (difference to L. cinereoniger), penes are everted and reach 50-75 % of body length. Dates of observed copulations were not recorded; life cycle unresearched.
