I think it's a Miridae nymph corpse, Stenodemini tribe and probably Trigonotylus caelestialium or Trigonotylus ruficornis.

Well, at least gives us clues about what may be and which are less likely.
In my case, Tenebrionidae fail a lot, for example, but it is a good website supported by European experts who work with their reviews. Other sites dealing with specific groups, but usually try to countries or regions.
I remember seeing P.V. Putshkov, famous expert in Heteroptera. In Miridae, the reference is the work of Kerzhner IM, M. Josifov (1999) although there are many updates to other experts.
