Discussion.
This variety was described to allocate specimens for which the single conchological character noted by Roffiaen (1868) was the “ pale greenish colour ”. The shell of Discus ruderatus is known to typically to be light brown to reddish brown ( Welter-Schultes 2012), though paler yellowish and greenish brown specimens are also common ( Kerney et al. 1979; Wiese 2014). Furthermore, the type locality of this variety is within the known distribution of D. ruderatus in Switzerland ( Turner et al. 1998), and Roffiaen (1868) himself mentioned “ typical ” D. ruderatus occurring in the same place. Thus, even without access to type material, it can be surmised that Helix ruderata viridana is very likely a junior synonym of D. ruderatus .
