Scientific Name: Xeromunda durieui (L. Pfeiffer, 1848)
Taxonomic Notes: The Italian occurrences of this species have for a long time been considered as Cernuella durieui candiota (Mousson, 1854) (Forcart 1965); however, Manganelli and Giusti (1989) pleaded for a specific separation of the eastern (Cernuella durieui candiota) and western (Cernuella durieui durieui) Mediterranean forms. Still, this problem of the specific differentiation is not satisfactorily resolved, and so we follow the view Manganelli and Giusti (1989).

Assessment Information [top]

Red List Category & Criteria: Near Threatened (Regional assessment) ver 3.1
Year Published: 2011
Date Assessed: 2011-03-27

In Europe, this species lives only in a restricted area in South Italy (coastal area of Basilicata, and Puglia), where it occurs in  nine isolated localities living on sand dunes. The European occurrences are of conservation interest under assumptions of their origin. As an isolated relict of migrations in geological times, it would indicate the existence of former land bridges. If considered introduced by human, it would be a remarkable evidence of ancient trade. Due to the fragmentation of its distribution area, it is assessed as Near Threatened (NT) at the European level and at the level of the 27 member States of the European Union.

Geographic Range [top]

Range Description:The main distribution of this species is the Mediterranean coastal area of northern Africa from Algeria to Libya. In Europe it is only present in scattered localities along the coast of the Gulf of Taranto (coastal area of Basilicata, and Puglia), Italy. It is unclear whether the European occurrences are due to past faunistic migrations from North Africa to Italy or whether they originate from an ancient anthropogenic introduction.
