Limnæa palustris var. pellucida Roffiaen, 1868: 79, pl. 1, fig. 7.

Type material.

RBINS I.G.7065 / MT.4175 : 1 holotype, ex Colbeau coll.

Type locality.

Switzerland: Altdorf, in a ditch on the plains towards Seedorf . “ […] dans un fossé de la plaine d’Altorf, vers Seedorf (M. Colbeau) ” ( Roffiaen 1868: 79).

Taxonomic status.

Junior synonym of Stagnicola palustris (O. F. Müller, 1774) (cf. Servain 1882; Hubendick 1951; Vinarski 2024).

Discussion.

Specimen RBINS I.G.7065 / MT.4175 stems from the collection of Jules Colbeau, comes from the type locality (Altdorf, spelled “ Altorf ” on the label as in the original publication) and is a good match to the published illustration ( Roffiaen 1868: pl. 1, fig. 7). Considering the original description was written using a single individual, the present specimen can thus be considered the holotype.

A possibility that the holotype could belong to S. fuscus cannot be rejected (see the discussion of L. palustris var. fallaciosa above).
