New records of Vertigo geyeri Lindholm, 1925, V. moulinsiana (Dupuy, 1849) and V. angustior Jeffreys, 1830 (Gastropoda: Pulmonata: Vertiginidae) in Poland

New localities of Vertigo geyeri Lindholm, V. moulinsiana (Dupuy) and V. angustior Jeffreys were found in 2011–2014, in three provinces in Poland: Wielkopolskie, Lubuskie and Podlaskie. The field survey was preceded by pinpointing potentially suitable habitats using maps, orthophotomaps and available botanical data. Each of 60 sites was explored in situ for molluscs for 60 minutes. We discovered 4 sites of V. geyeri (Podlaskie province only), 17 sites of V. moulinsiana (8 in Wielkopolskie, 5 in Lubuskie and 4 in Podlaskie) and 27 sites of V. angustior (5 in Wielkopolskie, 8 in Lubuskie and 14 in Podlaskie). In western Poland the vertiginids were found usually in wet or damp sedge meadows bordering lakes, small rivers or ditches whereas in the eastern part of the country the studied species were found in alkaline fens with thick brown moss layer.
