Now we need to know if there is a tiny tooth at the lower margin of the eye ("Abb. 1" in http://coleonet.d...toncus.htm). "No tooth" would lead to the Australian E. imperialis that is introduced in Spain. However, the the tips of its elytra are clearly rounded, which is not the case in your animals. That leaves us with E. ocularis and E. luteola. To tell them apart is difficult. E. ocularis specimens might be darker, but not necessarily. In E. luteola the tips of the front tibiae are said to show a sharp angle on the outside; visible in "Abb. 12". In E. ocularis the tips are rounded or show an obtuse angle at least. I see only one front tibia in the last picture, and its tip is not quite clearly recognizable... So: Epuraea cf. luteola. Perhaps you can check again.
