Horsák M., Čejka T., Juřičková L., Beran L., Horáčková J., Dvořák L., Coufal R., Maňas M. & Horsáková V., 2023: Check-list and distribution maps of the molluscs of the Czech and Slovak Republics. – Online at http://mollusca.sav.sk/malacology/checklist.htm, checklist updated at December 2, 2023, maps updated at April 18, 2023. https://doi.org/10.5281/zenodo.10263078

The current version of the check-list follows Horsák et al. (2013) with up-to-date modifications supplemented with a reference. Distribution map for each species was constructed based on published data and our knowledge based on unpublished records. So far 251 species of molluscs, including 223 species of gastropods (51 aquatic and 172 terrestrial) and 28 species of bivalves, have been found outdoors in the Czech Republic. The fauna of Slovakia comprises 260 species, including 231 gastropods (55 aquatic and 176 terrestrial) and 29 bivalves.

Abbreviations:
To the checklist: B – Bohemia; M – Moravia; S – Slovakia; ( ) – probably extinct species for the territory; [ ] – an extinct species for the territory; * – a non-native species for the territory; ? – an occurrence is probable, but not reliably confirmed yet; ! – an endemic species of smaller area.
To the maps: M – past distribution; R – recent distribution; M<R – number of occurrences increased over the last few decades (e.g. for non-native species); M>R – number of occurrences declined over the last few decades (e.g. for seriously threatened species); M=R – no obvious changes in the species distribution.

Updates are marked by underlining and commented below the list of species.

Comment to Bythinella species

Bythinella austriaca (von Frauenfeld, 1857) – There are three more species, by their shell morphology similar to B. austriaca, reported from Slovakia: B. hungarica (Hazay, 1881), B. metarubra (Falniowski, 1987) and B. steffeki Grego & Glöer, 2019. The latter species has been described based on a single population in the Slovenský kras Mts., the area with frequent occurrence of B. austriaca, using only shell and genital morphology. It has been unshakeably proven (e.g. Bichain et al. 2007) that classical morphological descriptors may not constitute valid specific criteria within Bythinella. Without an integrative taxonomical study, delimiting these putative species based on both mitochondrial and nuclear gene fragments, and without the association of these species with shell morphology, we cannot accept these names as biologically valid taxa. There is no evidence to support an assumption that these species are not only extremes within (eco-)morphological plasticity of a single species, i.e. B. austriaca. Grego & Glöer (2019) stated: “The COI sequence in the GenBank under number MK673142 indicates a close relation of the new species to some of the B. austriaca clades.”, which in other words says that there is no genetic difference (at least based on COI gene) between B. austriaca and B. steffeki. The phylogenetic analysis published by Benke et al. (2009) clearly showed that B. austriaca and B. metarubra are genetically the same.

Comments to species names and new records

Viviparus acerosus Bourguignat, 1862 – for the first time recorded in Bohemia in 2015, see Beran et al. (2019).

Clathrocaspia knipowitschii (Makarov, 1938) – for the first time recorded in Slovakia in 2019, see Szekeres et al. (2022).

Hauffenia kissdalmae Erőss & Petró, 2008 – see Haase et al. (2021).

Hauffenia lozekiana Haase, Grego, Eröss, Farkas & Fehér, 2021 – see Haase et al. (2021).

Stagnicola palustris (O. F. Müller, 1774) and Stagnicola turricula (Held, 1836) – taxonomic status follows Pieńkowska et al. (2015a).

Ladislavella Dybowski, 1913 – originally as Catascopia Meier-Brook & Bargues, 2002. Nomenclature follows Pieńkowska et al. (2015a) and Pieńkowska & Lesicki (2018).

Ladislavella occulta (Jackiewicz, 1959) – European populations were for some time reported under the name L. terebra (Westerlund, 1885), see Pieńkowska & Lesicki (2018). The first record in Slovakia near the village of Senné (Čejka et al. 2020).

Radix lagotis (Schrank, 1803) – for the first records, see Čejka et al. (2021).

Physa acuta (Draparnaud, 1805) – see comments in Welter-Schultes (2012), p. 56.

Gyraulus parvus (Say, 1817) – current genetic investigation revealed that G. parvus and G. laevis are in fact part of the same species-level clade, with the former having nomenclatural priority (Lorencová et al. 2021). However, the structure within the mitochondrial tree suggests a North American origin of the invasive populations, earlier reported as G. parvus. It also suggests that although the native race in Europe, i.e. G. laevis, tend to possess some differences in conchology and ecology, the degree of overlap between the races makes it impossible to accurately distinguish between them without the DNA barcode data.

Ferrissia californica (Rowell, 1863) – originally as F. fragilis (Tryon, 1863), see Christensen (2016). Sometimes even a month matters in description of a new species.

Pupilla alpicola (Charpentier, 1837) – conspecific with Pupilla pratensis (Clessin, 1871), see Nekola et al. (2015).

Pyramidulla saxatilis (Hartmann, 1842) – species resurrected based on DNA from synonymy with P. rupestris, but it cannot be differentiated by shell morphology from P. pusilla. Only one site has been reported from Veľká Fatra Mts. based on DNA analysis of specimens from that site, see Kirchner et al. (2016) and Razkin et al. (2016, 2017).

Vertigo arctica (Wallenberg, 1858) – Nekola et al. (2018) consider it as a separate species, phylogenetically not closely related to V. modesta (Say, 1824).

Macrogastra borealis (Boettger, 1878) – Due to some nomenclatorial issues (see http://www.animalbase.uni-goettingen.de/zooweb/servlet/AnimalBase/home/speciestaxon?id=15626) the well-known name Macrogastra latestriata (Schmidt, 1857) had to be substituted by M. borealis (Boettger, 1878).

Euconulus alderi (Gray, 1840) [syn. E. praticola (Reinhardt, 1883)] – taxonomy and nomenclature follow Horsáková et al. (2020).

Tandonia kusceri (Wagner, 1931) and T. rustica (Millet, 1843) – see Korábek et al. (2016a).

Ambigolimax valentianus (Férussac, 1822) – for the first time recorded outdoors in Slovakia in 2020, see Čejka et al. (2021). Originally as Lehmannia Heynemann, 1863, for the current genus assignment see Nitz (2013) and rowson et al. (2014).

Limacus maculatus (Kaleniczenko, 1851) – for the first time recorded in Moravia in 2019, see Čejka et al. (2020).

Lehmannia carpatica Hutchinson, Reise & Schlitt, 2022 – originally reported as L. nyctelia (Bourguignat, 1861) and later also as Ambigolimax nyctelius (Bourguignat, 1861); see Nitz (2013) and rowson et al. (2014) for details. Hutchinson et al (2022) noted that the name L. nyctelia (Bourguignat, 1861) was used for five different species and raised the new name for the Carpathian populations as L. carpatica, since the original name Limax nyctelius, based on the Algerian matrerial, is now to be known as Letourneuxia nyctelia (Bourguignat, 1861).

Deroceras invadens Reise, Hutchinson, Schunack & Schlitt, 2011 – for the first time recorded in Bohemia in 2014, see Hutchinson et al. (2014); and in Slovakia in 2017, see Čejka (2018).

Monacha claustralis (Rossmässler, 1834) – originally reported as Monacha cantiana (Montagu, 1803) by Hlaváč & Peltanová (2010); for further details see Pieńkowska et al. (2015b).
