Martin,
thanks for your nice Plate.
It looks like a
Pseudomalus auratus (Linnaeus),
however, in Denmark there's an other similar species:
Pseudomalus triangulifer (Abeille).
The latter is recognizable by antenna long and slender, with medial flagellomeres longer than broad (l/w> 1) and apical notch of T-III triangular, not deeper than broad. I cannot see these characters from the Plate, but you could examine at the microscope.
Cheers
Paolo
