Report on a collection of terrestrial molluscs (Gastropoda, Pulmonata) from central/north-western Namibia with the description of a new species of Sculptaria (Sculptariidae)

Land mollusc material collected by the second author in 2001 in central and north-western Namibia is discussed; it contains the new species Sculptaria fumarium (Gastropoda, Pulmonata: family Sculptariidae/Corillidae) from the southern margin of Etosha National Park. This species is characterized by a peculiar sculpture that might have survival value in arid surroundings. The collection contains 17 species, among which two alien taxa (Zonitoides arboreus and Deroceras leave), and encompasses a number of new distribution records.
