Since the last comprehensive overview of the Czech and Slovak mollusc
        fauna, released in 2013, several records of species new for the
        countries or particular regions have appeared. In this paper, we
        summarize all such records and news collected in 2015–2019, including
        those affecting nomenclature and the national Check-lists made in 2013
        and 2014. The rules for the selection of the records are: (i) the first
        record in Bohemia, Moravia or Slovakia, (ii) regionally important new
        records, (iii) records of species listed in NATURA 2000 and the national
        Red-lists as either critically endangered or endangered species, and
        (iv) currently spreading non-native species. New records are briefly
        commented and summarized for each species separately. Location data are
        published with all details in a supplementary table and are freely
        accessible.
