Dear Max, I am more and more convinced that your species belongs to Oberea.
I will look toward this direction.

Thanks, Francesco. But i`m don`t undestand really differences between Oberea\Obereopsis except long metafemur and size of body.. Very doubtless this species was be described among Obereopsis. Or i`m wrong?

I have found that the pattern of your species corresponds to the Taiwanese Obereopsis lineaticeps (Pic, 1911) (here), but the length of the merafemurs seems to me different.

Yes, it is very similar.. Apex of metafemur reach out for 1\3 of third abdominal sternit (for female) and more than 1\2 of 3 abd. sternit (male). All right i think ^)
The angle shot can be deceiving in stacking method. Great.
Thank You so much.
