Another similar image. Can this be identified to species?

Yes Gabor, it's
Morellia. Difficult to give definitive ID, but given the frons width, the very dark scutum with pruinose midstripe somewhat shortened, could be
Morellia simplex.

Thx Stephane.
In Hungary only two species are common: simplex and hortuorum. How can you easily distinguish them? My keys rely on characters that are only visible from the lateral view, which I do not have, and many of them need a microscope anyways.

If we had to compare males of M. simplex and M. hortorum, we could use the frons width :
At narrowest point,
M. simplex has almost touching orbital plates,
M. hortorum has frons 1.5 times as wide as flagellomere.
