First observation of Cantareus apertus (Born, 1778) (Gastropoda, Eupulmonata, Helicidae) in Serbia

[https://doi.org/10.5817/MaB2025-24-43]
We report the first documented occurence of the allochthonous green garden snail, Cantareus apertus (Born, 1778), in Serbia. The single individual was found in a plant nursery in the city of Novi Sad. This is the eighth allochthonous helicoidean in Serbia.

Revizní průzkum vodních měkkýšů Moravské Dyje [Revision survey of aquatic molluscs of the Moravská Dyje]

[https://doi.org/10.5817/MaB2025-24-37]
The Moravská Dyje is a smaller river in the Czech Republic and Austria, which is one of two sources of the river Dyje. During surveys in 2022 and 2024, 21 species of aquatic molluscs (13 gastropods and 8 bivalves) were found at 31 sites in the Czech part of this river. Notable finds include the populations of Unio crassus sensu lato (U. crassus sensu stricto and U. nanus), the species of European importance. A large population was found in the lower section of the river Moravská Dyje on the border with Austria. It can be assumed that the main part of the population occurs in the Austrian part of the Moravská Dyje (Mährische Thaya).

Malacological news from the Czech and Slovak Republics in 2024

[https://doi.org/10.5817/MaB2025-24-24]
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).

Two instead of one: citizen science and range clarification of Helix thessalica and H. pomatia (Gastropoda: Helicidae) in Ukraine

[https://doi.org/10.5817/MaB2025-24-17]
Numerous observations by amateur naturalists, together with some literature data and the malacological collection of the State Museum of Natural History in Lviv, helped to clarify the present ranges of two large and similar land snails, which were previously considered to be one species, Helix pomatia. It has been confirmed that the true H. pomatia is widespread in Ukraine, both within its probable natural range and due to anthropochory. The known range of H. thessalica extends in a rather narrow strip from the west to the east of the country. In Western Ukraine, it avoids both the mountainous part of the Ukrainian Carpathians and many plain areas. It also avoids the mixed forest zone in the north of Ukraine and the steppe zone in the south. This paper completes a series of publications on the present distribution of Helix species in Ukraine.

Společenstva vodních měkkýšů NPP Řežabinec se zaměřením na vzácné a ohrožené druhy [Aquatic mollusc communities of the Řežabinec National Natural Monument with a focus on rare and endangered species]

[https://doi.org/10.5817/MaB2025-24-8]
The Řežabinec National Natural Monument is located near Ražice in South Bohemia (Czech Republic). It consists of a pond created on the site of wetlands in the former bed of the Otava River, as well as pools and wetlands formed by the flooding of pits after mining. During surveys in 2014 and 2024, a total of 24 species of aquatic molluscs (17 gastropods and 7 bivalves) were found. The most important find was the pea mussel Euglesa pseudosphaerium. Its large populations were found here during both surveys in the wetlands around the pond and in the pools and wetlands east of it. This species is rare and critically endangered in the Czech Republic and occurs in shallow and overgrown pools. It has not been recorded anywhere else in South Bohemia. In the 10 years between the two surveys, there were only minor changes in the composition of mollusc assemblages.

Ulitníky pseudokrasovej tiesňavy Parkaň v pohorí Bachureň na východnom Slovensku [Gastropods of the Parkaň pseudokarst gorge in the Bachureň Mountains in Eastern Slovakia]

[https://doi.org/10.5817/MaB2025-24-1]
A pseudokarst gorge with the local name „Parkaň“ is located near the village of Renčišov in the Bachureň Mountains. This area was surveyed in 2023. In total, we recorded 52 species of terrestrial gastropods. These were predominantly forest species (38; 73%), euryvalent species were less represented (13; 25%), and one open country species was also found (1; 2%). The local microtopographic diversity (moist rubble, rock walls covered with moss, dead wood) with historic habitat continuity support the high species diversity of the gastropod fauna. The results highlight the conservation importance of the area and the presence of sensitive species such as Argna bielzi, Macrogastra tumida, Pseudalinda stabilis and Bulgarica cana, indicating the well-preserved state of the habitat. This area represents a local diversity hotspot surrounded by mostly disturbed production forest monocultures. The discovery of one, slightly damaged shell of the species Helicigona lapicida is interesting. Since we could not find live individuals, we do not consider this finding a reason to include the species in the malacofauna of Slovakia.

We report the first record of Pseudosuccinea columella (Say, 1817) from Serbia. This finding in the Tamiš River clarifies its presence in Serbia which was questioned in the 2021 checklist, as it was previously confused with succineid gastropods. The habitat is described in detail and its possible way of introduction is discussed.
