The area of Beaufortain (French Alps) was examined for the presence of Eucobresia diaphana and other Vitrinidae species on July 27 and 28, 2015. On both Col du Mont Joly and La Vacherie, glass snail species were observed. The species encountered were Eucobresia diaphana, E. nivalis and Vitrina pellucida. These species were observed in low numbers only. Multiple empty shells and one live animal were found. The particular warm spring and associated relative dryness possibly explain these low numbers. Beside these glass snails, other mollusc species were encountered as well. More information on the occurrence of Eucobresia diaphana in France is required for an ongoing investigation of the range of this species. We are interested in all reliable records of this ear-shaped glass snail. These records may include species identified on the basis of their complete shells including a visible strophostyle columella and/or animals that are identified on the basis of their genitals. Please contact Kees Margry if you have stored materials and/or photos available in combination with information on site, coordinates, altitude and date of collection.
