Abstract
A total of 17 freshwater and 33 land gastropod species as well as 6 small clams from different habitats were found during a study of limnic and terrestrial molluscs in central and northern Lebanon. New records for Lebanon or the Levant countries include Stagnicola cf. berlani (Bourguignat, 1870) sensu Kruglov, 2005, Planorbis carinatus O. F. Müller, 1774, and Potamopyrgus antipodarum (J. E. Gray, 1843) as well as the clams Musculium lacustre (O. F. Müller, 1774), Pisidium amnicum (O. F. Müller, 1774), and Pisidium tenuilineatum Stelfox, 1918. Among the land snails, Orculella mesopotamica riedeli Hausdorf, 1996, Buliminus damascensis (Pallary, 1929), Turanena benjamitica (Benson, 1859), Sphincterochila fimbriata (Bourguignat, 1852), and Monacha cf. compingtae (Pallary, 1929) are new for Lebanon.
