This paper presents important faunistic records including location
data with all details conducted in the Czech and Slovak
Republics during 2020. Four new non-native species, Arion
intermedius, Ambigolimax valentianus, Clathrocaspia
knipowitschii and Krynickillus melanocephalus, were
recorded outdoors in Slovakia. Radix lagotis was genetically
confirmed for the first time from several sites in the Czech Republic
and Slovakia. Corbicula fluminea, recorded in Moravia for the
first time in 2018, was found in another river, ca 50 km far from the
first occurrence. Cepaea nemoralis, recorded in Slovakia for
the first time in 2015, seems to have started spreading. New sites of
Cornu aspersum were noticed in Prague and Bratislava; for the
first time it was also found in Brno. There are also new records of
several endangered species, e.g. Vertigo moulinsiana, Pisidium
hibernicum, P. globulare, and Pseudanodonta
complanata, presented.
