Then akulich-sibiria:
Both Chrysobothris-Ch. chrysostigma.
Ch. solieri-are Southern European, most likely not found in Russia
. встречается.Сһ. igniventris sporadically in the south of ETR.
But they should not have such edges.

Ciid, alas, I don't know...

Thank you, well, we can say with some confidence that these are exactly the cyids?
And according to zlatke, at first I had exactly the same species named (Ch.chrisostigma), but I was confused by the fact that the supracroic keel of the pronotum was not complete and not so obvious. And something with the prothorax process was not quite going smoothly. (Definition of species by the Fauna of the USSR). But at the same time, the ribs on the elytra are very pronounced. And variations in the color of the shield, within the species-can this be??..
Another question about goldfish-Buprestis (=Ancylocheira) hemorrhidalis lives in Siberia??...We come across B. sibirica

Then akulich-sibiria:
Yes, that tsiida-exactly.
As for the color of the shield, I think it's quite likely.
Buprestis haemorrhoidalis ssp. sibirica Fleischer, 1887 it is called, and therefore inhabits

The fact is that the species Buprestis haemorrhoidalis and B. sibirica Fleischer, which is different from it, are described in the fauna of the USSR, but I also often found that this is exactly how the subspecies goes. Morphology is well described in this guide. So, out of 10 goldfish with obvious signs of B. sibirica Fleischer, I came across a goldfish with clear signs (as it seems to me) for the Buprestis haemorrhoidalis species listed there. If you are interested, then I can then throw off a number of signs that I think there are differences in.

Another question about Sphenoptera goldfinches..I have two views here. I would like to know what species can be found here (Krasnoyarsk Territory, Khakassia). Faced with difficulties in determining. Determined by DV and green. It's a pity that there are different types and there is no common table with all the views. Here we have one species each for S. arnoldii and S. extensocarinata..can we have these types?? photo maybe a little later I'll post today

1,2 - Criocephalus rusticus
5 - Phytoecia ? cylindrica
6 - Clytus arietis
7 - Phytoecia (Opsilia) coerulescens
8 - Chlorophorus figuratus
9 - ? Chlorophorus sartor
11, 15 - Leptura ? qudrifasciata
12 - Stenocorus ? insitivus
13-Strangalia attenuata
14, 17-Rutpela maculata
16 similar to 13, only female...

Fornax:
that's what I picked up on the pig pan.. I decided that there was a wide depression on the pronotum.. It's not deep and barely visible, but it looks like it.. Even in the photo a little visible in small..
the color is bronze-blackish-copper.. kind of

keel on the elytra like to the end.. But there is a strange thing - if you look from the side, the keel is visible, and if from above, it seems to smooth out towards the middle.. By the method of poking and making decisions, I decided that all the same keel to the end.. And I found a photo of Kuprina, which looks different.
So it comes out lutschniki, Prague???7 0_o

In general, in this regard, I suggest organizing a Swineherd gallery, even if they are not defined. We need some material for comparison, otherwise it's a bit difficult to determine.. And if the group is not studied, then it's worth a try. Photo with details to determine.

egzarata does not fit on the shield - these have it as a lying rectangle, and egzarata has more standing (i.e. the ratio of the length of the width of the shield..)
in these, under the binocular lens, there seems to be a border on the top of the pronotum, such a thin one, but the border.. egzarata shouldn't have it.

as an option, maybe antiqua, but there also seems to be small discrepancies..
the process of the pgr on the sides has grooves, but not from points, but just grooves.
by the way, the size of the ekz is 11-12 mm, so not egzarata for sure..
about anti-kva confuses the color, and small dotted lines between the points of the pronotum.. I would not say that something can be called a very fine dotted line, but it is also difficult to call a smooth surface..

purely from the description, it looks a little like lateralis and dianthi, although the shield can hardly be called barely transverse..

generally gibberish.. The definition of the occupation is interesting, but such keys, in my opinion, are clueless, especially when talking about points on the pronotum, which are generally difficult to characterize

, they could draw at least caprints of what they wanted to say.. And then half of the species have to be implied in one interpretation or another..
