hello
i have photographed a strange Hemiptera in Romania. i first believed is a Nabis sp. , but today i have read that Hemiptera order have only 4-5 antennae segments.
so this species is strange because have many segments.

any idea what order or family it may be ?

Maybe Plecoptera...Stonefly?

The main thing to remember are the key features that define the insect orders - for Hemiptera they pretty much all have long, piercing mouth-parts so a long proboscis would be expected - not mandibles as in this case ;) As Roger said, looks like Plecoptera to me :)

i know that Miridae & Nabidae species that i photographed had a proboscis, that is why i have put the first picture.

however this is first time when i hear about Stone Flies.

Plecoptera is correct. If dorsal side, wing venation visible, a family name may be found.

I don't have a wing venation picture. The subject wasn't cooperative. :|
