If you've had a look at the other species of this genus within the Valais section you will appreciate the difficulty of identifying them. Looking at the underside does help a little, none of the underside photos were good enough to put in theses pages, good enough to help identification though.

These particular specimen are from Hautes Pyrenees.

Mark Ogden took this underside picture in the Dolomites in 2005.
