Pupa tabularis Melvill & Ponsonby, 1893, a new synonym of Lauria cylindracea (Da Costa, 1787) (Gastropoda Pulmonata: Pupillidae)

Examination of the type material of Pupa tabularis Melvill & Ponsonby, 1893, in the Natural History Museum, London, has shown that this name is a junior synonym of Lauria cylindracea (Da Costa, 1787). This automatically adds another alien species from the Palaearctic Region to the South African list, although this is within the natural range of the genus. A summary discussion on the distribution of the genus is appended.
