Hello Juri,
It belongs to genus Acolastus, as I think.
There is a recent work from Matthias Schöller about this genus in Arabian peninsula (8 species), open in the Internet.
With an identification key and some photos. In Oman 4 species.
You can see here:

Thank you George.
With the key of the article above I think:

Acolastus substriatus (Medvedev, 1996) to 51% or Acolastus loebli Schöller, 2018 to 49%.

One of them but I have only this specimen.
I have to examine the aedeagus if it is a male.
Of course a specialist of Chrysomelidae will be able to say more.
I hope he will pass by here ...

Really, it is hard to choose between these 2 species.
PS. It is very strange that Gerstaecker decided to give the name "Acolastus" to this genus.
This is a Greek word (ακόλαστος), meaning "lecherous", "libertine" or "without moral barriers" !!!
