The first annotated checklist of the molluscs of the Republic of Moldova, which included 112 species, was published recently (COADĂ & WELTER-SCHULTES 2011), but unfortunately some literature data were overlooked and this list was incomplete. Moreover, some unpublished data from collection material became available in the last few years. This created a need to update that previous checklist. Our new checklist includes 155 species: 26 bivalves, 45 freshwater gastropods and 84 terrestrial gastropods. Since views on taxonomy of the freshwater molluscs are quite controversial, we follow here mainly a recent guide of European non-marine molluscs (WELTER-SCHULTES 2012) to make the list better available to the European reader. A list of the freshwater molluscs of the Republic of Moldova in the classification applied by the Russian malacologists of Starobogatov’s school was published recently and included 100 species (MUNJIU 2012). We did not try to make any nomenclatural revision here, but intended only to adapt this list of 100 species for the European reader. Since STAROBOGATOV and his followers frequently use specific names not in the sense of their original authors (for most complete list see: STARO-BOGATOV et al. 2004), we could not just list these additional names as synonyms of recognised species. Many of these names are not synonyms in the taxonomic sense (which would require studying the type material), but only synonyms in the sense of these authors. We can only suggest from our experience which species can more likely be understood or determined under these names. Names that are marked by “auctorum non...” refer to a synonym in the sense of some authors (here mainly STAROBOGATOV and his followers) but not the author of the species name. However many of these names are nomina dubia without types and we did not study this problem in detail, so it is also possible that some of these names are actually correct synomyms in the sense of their authors. For this reason we mark such names with “auct. non
