The correct name of the baleen Kopieuska is Myrmeleotettix antennatus (Fieber, 1853). As for the herb-it is possible that haemorrhoidalis, but, in my opinion, there is a reason to get involved. What color are her palps-solid or dark with light rings? I am actually struck by the difference between your copy and my Pskov collections. Especially in the pattern of the lateral lobes of the pronotum. It is clear that this is not a trait that is not subject to variability (O. viridulus, for example, has at least three variants of the color pattern of this part of the body) - but nevertheless. I would like to record songs and listen to them...

The palps are dark with light rings, and the apical ones are whitish, the rings
are not visible. What does this mean ?
In general, there were few of them, only one copy. I got caught (I took everything in a row).

1st - not biguttulus, anyway. I don't know about mollis, because I haven't dealt with it much. It doesn't look like the Pskov ones, but similar ones were caught in Moldova. Brunneus, of course, is most likely.

2nd - from the albomarginatus group. Also a difficult group, by the way. Look for jobs. von Helversen, mainly-information about areas. Because there is an assumption that without data on courtship behavior (not even calling signals), it is impossible to accurately determine.

I noticed that for fins, mollis is not specified, so brunneus comes out as an exception method. Is mollis more southern ?
Do you know if there is a mollis in the Leningrad region ?
Well, biguttulus, of course, disappears on the wings.

But with albomarginatus, you surprised me. I thought it was this particular view.
There are also light rays on the elytra and the shape of the pronotum is the same as it should be in albomarginatus.
Any new data on twin species ?

Dorsatus, in fact, has color variability, and it is quite pronounced. In the Pskov region, I encountered 2 main patterns: a green top with brown sides and completely brown ones. In the collections from the south of Russia, there were also completely green ones. So you should not be

afraid of the non-greenness of this species at all - it fits perfectly.

Now about the bottom one. Look at the shape of the hearing organ. If it is narrow , it may even be from the brunneus/biguttulus/mollis group. I rarely saw skates from this group with this color. Oddly enough, they have a green color, and its location is found in two versions:: as in this photo and as in Omocestus haemorrhoidalis from my photo above. I caught the 1st option in Pskov region (?brunneus) and in Moldova (? mollis), 2nd (?biguttulus) - between Toksovo and Kavgolovo near St. Petersburg.
