Abstract

Building on the recent re-allocation of Helix sordulenta to the genus Schileykiella, this paper provides further insights into the taxonomy, palaeontology, and distribution of Schileykiella in North Africa. Additionally, the taxon Helix mendicaria L. Pfeiffer, 1860, described from Tunisia, is here proposed as a junior synonym of Schileykiella sordulenta (Morelet, 1851), and the taxon Xerophila chadiana darnensis Hey, 1955, described from Derna (Cyrenaica, Libya), is identified as a possible congeneric fossil species.

Abstract

A comprehensive survey on the Cochlostomatidae from Northern Africa is given, based on a critical examination of the type specimens of the described nominal taxa. As a result, five species are accepted to occur in Northern Africa: Cochlostoma letourneuxi (Bourguignat, 1866) from Tunisia and Algeria, C. atlanticum (Bourguignat, 1868) from Algeria, C. barcaense Brandt, 1958 and C. susaense Brandt, 1958 from Libya and Obscurella marocanum (Pallary, 1928) from Morocco. New records of C. letourneuxi for Tunisia are provided. The shell of each species is described and illustrated, synonyms are listed, and a distribution map is provided. A lectotype is selected for Pomatias letourneuxi; Pomatias tunetanus is selected as type species for Tunetana A. J. Wagner, 1897.
