METHODS

In view of the fact that the last list of Czech molluscs was published in a book dealing with Quarternary molluscs, where slugs were not commented (Ložek 1964), we adopted the key of Czechoslovak molluscs (Ložek 1956) as the more suitable base-line. Therefore, references are given for all species firstly recorded in the Czech Republic after 1956. This checklist originated from the previous work by Juřičková et al. (2001), which was complemented by new information.

The territory of the Czech Republic was divided into two parts (Bohemia and Moravia including the Czech part of Silesia) on the basis of historical development. This subdivision has lost its administrative role but is traditionally used in biological research. Bohemia is constituted by a single biogeographical subprovince (Hercynicum) whereas Moravia is constituted by four subprovinces (Polonicum, Carpathicum, Panonicum and Hercynicum). This is the main reason for the different distribution of some species.

The classification is according to Turner et al. (1998) with small modifications based on new information. B - species occurs in Bohemia; M - species occurs in Moravia and Silesia

Explanations until 2001 (see Juřičková et al. 2001), complemented and modified:

¹⁾ missing or extinct species

²⁾ non-native species

³⁾ this taxon was subdivided into more species [in the Czech Republic Stagnicola palustris (=turricula), S. occulta, S. fuscus, S. corvus]

⁴⁾ problematic taxon (compare Jackiewicz 1993 versus Glöer & Meier-Brook 1994, Fechter & Falkner 1990 and Turner et al. 1998)

⁵⁾ problematic form

⁶⁾ eusynantroph

⁷⁾ taxonomic position of this species is still problematic, some authors do not adopt it and consider this species synonymous with Candidula unifasciata

⁸⁾ in southern Moravia probably native
