Notes

Shell yellowish-brown, dextral, medium-sized, thin, almost transparent, globular, with 5-6 coils; sutures well evident; umbilicus large, deep, funnel-shaped; peristome unfolded and thin. Some specimens were collected at a depth of up to 50 cm along the Raibano Valley path. Normally, R. o. olivetorum inhabits shady hill and mountain meadows in chestnut and olive woods ( Cossignani and Cossignani 1995, Welter-Schultes 2012, Cossignani and Cossignani 2020). It can survive drought inside the soil and appears only during and after longer rainfalls ( Welter-Schultes 2012).
