This is a list of the non-marine molluscs of the Czech Republic. That country is land-locked and therefore it has no marine molluscs, only land and freshwater species, including snails, slugs, freshwater clams and freshwater mussels. There are 247[1] species of molluscs living in the wild in the Czech Republic. In addition there are at least 11 gastropod species surviving in greenhouses.
There are 219[1]gastropod species (50[1] freshwater and 169[1] land species) and 28[1]bivalve species living in the wild.
There are also 11 introduced gastropod species (5 freshwater and 7 land species) and 4 bivalve species living in the wild in the Czech Republic. This is a total of 9 freshwater non-indigenous species living in natural habitats.
5 freshwater[1] (Bithynia troschelii is non-indigenous in Bohemia and indigenous in Moravia) and 7 land[1] (2 are in Moravia only, 3 are in both, 7 are in Bohemia only)
Historical lists from 19th century or overviews of Czech malacofauna include works by Schöbl (1860), Slavík (1868) and Uličný (1892–95).[2][3]
Lists by Vojen Ložek include work Ložek (1948) for Bohemia. Following works include lists for whole Czechoslovakia for recent species: Ložek (1949), Ložek (1956)[4] and list including Quaternary species: Ložek (1964).[5]
Lists for freshwater species include: Beran (1998)[6] and Beran (2002).[7]
Conservation status of all 237 species include list by Juřičková et al. (2001).[8] There is also available red list based on that 2001 list.[9] Threatened species only include list by Beran et al. (2005).[10] List by Juřičková et al. (2008)[11] has included 245 species. List by Horsák et al. (2010) has included 247 species.[1]
There are only families and species in the list. The Czech name is in parentheses. Listed is the occurrence in Bohemia or in Moravia (and if it is a non-indigenous or locally extinct species). Non-indigenous species only occurring in greenhouses in the Czech Republic are noted separately after the list. Freshwater gastropods in the Czech Republic include:
(bahnivka nadmutá) Bithynia troschelii (Paasch, 1842) – non-indigenous in Bohemia, native in Moravia.[1] It was thought to be locally extinct in Moravia. It was rediscovered in 2008.[12]
(zrnovka slatinná) Pupilla pratensis (Clessin, 1871)[13]Pupilla pratensis was elevated to its species level in 2009.[14] The later revision showed that Pupilla alpicola does not live in the Czech Republic and all of them are Pupilla pratensis in that country.[13]Pupilla alpicola (Charpentier, 1837) (in Czech: zrnovka alpská) has been listed as a part of fauna of the Czech Republic for a long time (as probably extinct in Bohemia and critically endangered (CR) in Moravia).[1][15]
(tmavoretka kentská) Monacha cantiana (Montagu, 1803) – claimed to be non-indigenous in Bohemia since 2009,[23] but based on a misidentification of M. claustralis[24]
These species do not live in the wild or are not recorded in the wild yet, but they live in greenhouses and similar biotopes, as "hothouse alien" species.[30][31][32]
List (alphabetically according to their scientific name):
(okružákovec floridský) Planorbella duryi (Wetherby, 1879)[1] – It was incorrectly noted as Planorbella trivolvis (Say, 1817) (mentioned under invalid name Helisoma trivolvis).
