Clausilia plicatula var. albinos Roffiaen 1868

Clausilia plicatula var. albinos Roffiaen, 1868 Clausilia plicatula var. albinos Roffiaen, 1868: 76. Type material. Single specimen, at present not located. Type locality. Switzerland: Iseltwald. Taxonomic status. Junior synonym of Macrogastra plicatula plicatula (Draparnaud, 1801). Discussion. No specimens belonging to this taxon were found. The original description mentioned a single shell, whitish and transparent (hence, “ albinos ”), as belonging to this variety, while commenting that the nominate form is common and very variable (Roffiaen 1868: 76). Thus, this variety based on an albino specimen (or otherwise presenting partial or total loss of pigments) can be considered synonymous with the nominate form. Macrogastra plicatula is widespread in Europe, including many records in the area encompassing Iseltwald representing M. p. plicatula (Turner et al. 1998; Nordsieck 2006).
