Identification of beetles (Coleoptera)

here are some more pictures of ground beetles...
1. it is clearly visible that 2 setae behind the eye and on the penultimate palpel
Then pterostichus. I really don't think it's quite abstruse: try it before the subgenus.

2. and here is another one, he has a bump on the last stubble, maybe it's a male Pterostichus nigrita..?
The group seems to be the same. But with confidence in the Siberian pterosticham...
As variants:
nigrita Payk., 1790
rhaeticus Heer, 1837
pseudorhaeticus Solod., 2001

3. Is this Asa (o)phidion???
Yes, Asaphidion. Try using the ID of the DV. Maybe it'll do some good...

5. Amara..I can not go out on the keys to the view, about 7 mm, it has a greenish glow of elytra
Is Amara all the same. And what keys do you use to determine it?

6. this Amara has a three-pronged apical spur on the front tibia, it could be plebeja..??
A subgenus of Zezea, of course. Maybe plebeja (for me it is very similar), but there is still something there.

7. this beetle has segments of legs on top in hairs, Harpalus flies like, who can it be?
Not calceatus by the hour? On the last part of the legs from below there are spines, or only bristles?

8. and here's another elephant on a willow tree, Kuznetsk Alatau confusion full
of Ugh... What I write... Did Hyperina climb the willow tree? Maybe Donus what?

To akulich-sibiria:

And skrytnoglav where does the key go? Not in the flavipes group by any chance?

7. this beetle has segments of legs on top in hairs, Harpalus flies like, who can it be?
Possibly a former Pseudoophonus. Unfortunately, I don't know Siberians very well.

I went to it by the way, and why the former?? ... what is it called now??

Staf is similar to Nudobius lenthus when collected under the bark....

I found photos of similar types: (- although I don't know if this will clarify the question...)
"With the exception of blackpaw and bigeye, I'm leaning toward Syntomus obscuroguttatus." It's a pity I don't know their habitats...
"I'll try to get you a picture of him straightened up at home sometime.

- Here are 3 more photos: - dark forest!!! - probably you can't figure it out without the key method...

Yes not for what And what size skrytnoglav this?
Pseudoophonus is now also Harpalus sort of.

Well, this is a well-known beetle-Diaperis boleti (L.) is called. Few of the ETR beetles can stink LIKE THIS You won't believe it-chernotelka

- 3 days ago I caught a cow like this. "But it doesn't seem to be Halyzia sedecimguttata...?"

Please help me. Hidden heads were shot in Volgograd, the first in July on an oak tree, the second in September on wormwood.

  
4. 3-4. 07. 2008-Ukraine, Odessa region, Karolino-Bugaz village, on light, combining 18 W UV and 160 W DRV.

1-is it by any chance that a female C. coryli skidded on an oak tree? Only it looks quite brown. Or is it just a photo?
2-in my opinion, it is either Cryptocephalus (Asionus) flavicollis Fabricius, 1781, or C. (A.) quatuordecimmaculatus Schneider, 1792. To determine more precisely, you need to look at the structure of the belly and genitals of the male. In principle, both types are quite good.

Neighborhood of Yevpatoria, Crimea, June. They met in large numbers - 15-20 pieces were caught in 2 weeks.

The photo is not mine, the author of the photo is Maxim Kolomin

The first one was quite brown in color, it's a pity this is the only photo, the wind was blowing and at my approach the beetle fell into the grass, I didn't find it there.

C. flavicollis seems to be common in our region, but I didn't find anything about C. quatuordecimmaculatus in the Lower Volga region

Cool bug! Anoxia orientalis (Krynicki, 1832)

Thank you, but I already began to sin on some subspecies of Marble crunch Polyphylla Fullo )))

Cool bug! Anoxia (Protanoxia) orientalis (Krynicki, 1832)

Looks like I was in a hurry with the second one. Is his bottom all red?
