Six new subterranean freshwater gastropod species from northern Albania and some new records from Albania and Kosovo (Mollusca, Gastropoda, Moitessieriidae and Hydrobiidae)

摘要

During a field trip to the western part of the Balkan Peninsula in 2016, investigations of several caves and karstic springs revealed six new gastropod species living in subterranean waters and resulted in some noteworthy faunistic records. Five of the new species are assigned to the genus Paladilhiopsis Pavlovi????, 1913, namely P.prekalensissp. n., P.lozekisp. n., P.szekeresisp. n., P.wohlberedtisp. n., P.falniowskiisp. n. and one to the genus Plagigeyeria Tomlin, 1930, namely P.steffekisp. n. New Albania and Kosovo distribution records are given for Iglicaillyrica Sch????tt, 1975, Plagigeyeriazetaprotogona Sch????tt, 1960, Vinodoliamatjasici (Bole, 1961), and the first georeferenced record is given for Saxurinatorschlickumi Sch????tt, 1960. The most important environmental factors influencing habitat selection of these subterranean freshwater gastropods are briefly discussed.
