Aper u de la malacofaune de quelques tourbières alcalines du Plateau Bayard (France, Hautes-Alpes)

A malacological survey of highland alkaline fens of Plateau Bayard (Hautes-Alpes Département, Provence-Alpes-C te-d’Azur PACA Region here called PACA) was carried out in 2009 by litter sampling. Although it cannot be considered as comprehensive, it gave a preliminary list of species, including some noteworthy ones. Vertigo angustior Jeffreys, 1830 was found in four of the five fens, in habitats that had never been described before. We also report the occurrence of two species new for PACA Region, Vertigo substriata (Jeffreys, 1833) and Cochlicopa nitens (M. von Gallenstein, 1848).
