Occurrence : recordedBy: Pedroni ; individualCount: 2 ; occurrenceID: C232715D-7DF3-5EAB-A4B1-29665DE088EF ; Location : country: Italy ; locality: Near Brento , (10), PMS, Savena Valley ; verbatimElevation: 428 m ; Identification : identifiedBy: Pedroni ; Event : eventDate: 5.IX.2021 Notes Shell thick, smooth, medium-sized and flattened; 5-6 coils in adults; background colour white or white-yellowish, with variable bands, ranging from dark brown to black. Some specimens were collected below the walls of Monte Mario at a depth of about 40 cm. The subspecies is typical of xerothermophilic habitats, such as arid meadows ( Cossignani and Cossignani 1995 ), but also dunes, vineyards, ruins, roadsides and railway dams ( Welter-Schultes 2012 ). It is more active in winter than in summer, when it is active only at rainfalls ( Welter-Schultes 2012 ). It attains up to 2,000 m in the Alps ( Kerney and Cameron 1979 ); this is the first report for the Northern Apennine and Emilia-Romagna areas.
