This article presents important faunistic records carried out in the Czech and Slovak Republics in 2024. In 2024, many new records were made for non-native and currently spreading species such as for example Cornu aspersum, Krynickillus melanocephalus, Sinanodonta woodiana, and Tandonia kusceri. Krynickillus melanocephalus was recorded in Czechia for the first time. Melanoides tuberculata was confirmed at two outdoor sites in Slovakia, where it forms stable populations. The records of several native species include findings of protected and rare species (e.g. Euglesa pseudosphaerium, Gyraulus rossmaessleri, and Planorbis carinatus), but also still poorly known species (Euglesa globularis, and Sphaerium nucleus). In a separate section, we present records of two unintentionally introduced species reported for the first time for these countries from greenhouses (Ambigolimax parvipenis and Oxychilus translucidus).
