Inventory of land snails from the Kebir Rhumel basin, northeast of Algeria

ABSTRACT This study constitutes a first attempt at a qualitative and quantitative inventory of land snails from the Kebir-Rhumel basin, in the northeast of Algeria. Sampling was carried out by hand from February to March in 2018 and 2019. Live snails and shells were collected from 30 stations along wadi banks. Identification followed the most recent specialized taxonomic literature and revisions. A total of 6531 specimens were collected, representing 25 species: Tudorella sulcata (Draparnaud, 1805), Rumina decollata (Linnaeus, 1758), Rumina saharica (Pallary, 1901), Ferussacia carnea (Risso, 1826), Ferussacia folliculum (Schröter, 1784), Mauronapaeus terverii (Dupotet in E. A. Forbes, 1838), Mastus pupa (Linnaeus, 1758), Cantareus cf. koraegaelius (Bourguignat in Locard, 1882), Cornu aspersum (O. F. Müller, 1774), Cornu sp., Eobania constantina (E. Forbes, 1838), Eobania vermiculata (O. F. Müller, 1774), Helix melanostoma (Draparnaud, 1801), Massylaea massylaea (Morelet, 1851), Cernuella cf. virgata (da Costa, 1778), Cochlicella acuta (O. F. Müller, 1774), Cochlicella barbara (Linnaeus, 1758), Trochoidea pyramidata (Draparnaud, 1805), Xerosecta cespitum (Draparnaud, 1801), Xerosecta sp., Ganula flava (Terver, 1839), Sphincterochila candidissima (Draparnaud, 1801), Sphincterochila otthiana (E. Forbes, 1838), Sphincterochila sp. and Caracollina lenticula (Michaud, 1831). Typical specimens are illustrated and described with a detailed report of their distribution along the basin’s wadis.
