Ok,
This time I cannot help you.
Mocsary described Hedychrum semiviolaceum from Hungary and Austria.
I don't know the male of this species.
H. semiviolaceum has been considered as a synonym of H. nobile by all the Authors, except by Moczar (1964), how gave a key to separate semiviolaceum from niemelai.
It would be better to examine more specimens under the microscope ...
Ciao
