TachyporusTachinus?

Please help me deal with barbels
Primorsky Krai, okr. Ussuriysk.

I would still venture to call him Selatosomus caucasicus.

Feel free to

most likely T. fimetarius Gravenhorst, 1802. but without the beetle itself and edeagus, it is difficult to say for sure. so outwardly, 2-3 species are very similar to it - and the size would not hurt for reliability

Chlorophorus varius?
July, Saratov region.

yes, not the right word, But it is wide, winged clearly. Bright, of course, a little. I have one from Dagestan. But this is just a hypothesis, who seriously determines the selatozomus mountains in Troicard from the backside.. But it's plausible

Help with the monochamuses!
Khabarovsk Territory.
The size of the larger one is 22 mm, and the one on the right is 14 mm. I have a typical Urussovi and Saltuarius, these two are not like any of them. The one on the left has a divided shield, like a sutor, and the one on the right, next to the saltuarius, also looks like a sutor))
Caught in the same place at the same time.

Duc, both sutor and is - on the left a male, on the right a female.

Here's another photo, from a slightly different angle.

The right beetle is Monochamus impluviatus, in my opinion

Maybe. And by what signs can you definitely distinguish them? I'm reviewing it.

Is it all right that the left, larger beetle has a dent in the upper third of its elytra, a sort of "hump" like Urussova's?
I have several "sutors" with the shape of the elytra urussovi (dent), but with a divided shield.

Ulan-Ude 15 mm.
Pachycerus ?

And here is such a beetle. Caught in Reseni, settled down area, found already at home in a small series of worn Cleonis pigra. The only difference from them is the perfectly smooth top of the trunk. No trace of grooves or ribs. 10 mm. I suspect an anomaly in the development, but maybe something else, not pigra?
Please excuse the quality of the photo.

For me so shabby Adosomus roridus

Sorry, but it's not Adosomus granulosus. Although similar, it was taken from thistle, not wormwood. In addition, A. granulosus, it seems to me, lives much to the east. And I didn't notice any bumps in the last quarter of his elytra, but mine does, and they're well defined. Maybe there are some other options?
