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
