this should be a male of Chrysura radians (Harris), I'm quite sure even if the colour could deceive.
You can clearly see that is a male of Chrysura for the shape of the antennae in photos n°1.
In Southern Europe (Spain and Southern Italy) living males of C. radians can have more golden and red highlights on the thorax and more purple or violet reflections on the abdomen, as written on Fauna Iberica. What could be strange is the dark colour of the wings. According to the specimens in my collection I can say that males have darken wings than females, while Mingo writes "hyaline wings" in general, without notice any sexual dimorphic difference. If you read some diagnosis in Fauna Iberica, you can find dark wings only related to Chrysura simplex, but this specimen do not belong to C. simplex because of the shape of F-I (which is longer) and of the punctuation on T-II (even if not clear) and the general colour.
Last, but not least, C. radians is probably the most common Chrysura in Southern European mountains and hills.
