new records of vertigo moulinsiana (gastropoda: vertiginidae) and notes on its distribution and habitats in the czech republic

Vertigo moulinsiana (Dupuy, 1849) was found in 2003–2005 in Northern Bohemia (Czech Republic) at 11 sites. All these sites are situated on floodplains of smaller streams in a sandstone area. The known occurrence of this endangered relict in the Czech Republic is concentrated in three areas – a large area of Bohemian Cretaceous Basin, a floodplain near villages Břežany and Božice (Dyje River Basin) in Southern Moravia and small, isolated, treeless fens in the White Carpathians (Bílé Karpaty Mts.). The principal habitats where V. moulinsiana lives in the Czech Republic are sedge marshes, Typha swamps, reed swamps (with Carex spp.), alder carrs (also with Carex spp.) and tufa-forming spring fens.
