Theo can help better with these but I am not sure you'll get an identification. The genus contains many very nice, brightly-coloured, slightly variable and nearly identical species... and the situation gets worse in southern Europe :D

Then your problems have only just started!! ;) The general advice is that
Gymnosoma is a genus that needs serious revision... but nobody is brave enough to take it on! ;) The Central European key (Tschorsnig & Herting, 1994) is your best bet - let us know what you find :)
