Identification of beetles (Coleoptera)

Help me determine

Caucasus: Karachay-Cherkessia, Arkhyz, Dukka Lakes, 25.08.2016

These are amars of the equestris type, as I see it. I don't have Tsimindis, it doesn't look like ovipennis.
And the latrobius genitals need to be in profile, so that the curve at the base is visible (these are not paramers, they are reduced) and you can look at the Quaffe yourself for a start, there are a lot of them drawn, suddenly it will help.

A water lover can be identified by such a photo? Moscow, 5.5 mm, to the light
of some Enochrus?

Thank you, Maxim! At least some info!

Are the Amars the same? In one, I think the elytra are narrowed at the shoulders, and then expanded, and in the other-more parallel.

I still have about 20 undefined beetles from the Caucasus, mostly pterostichoamaro-harpalus beetles. I thought to take a picture of them, but since they are still undetectable, then there is no point in taking a picture somehow

Yes, they seem to be the same. This must be pastica (once treated as a subspecies of equestris). They're big, aren't they?
Cymindis angularis I have only one, Ivanovo, and although it is similar.. The dotted line is much rougher than mine, the back is red and all sorts of other little things. Besides, he doesn't live in the Caucasus. Somehow I didn't dare.
If you shoot about twenty pieces, then purely probabilistically you will probably find out something, although all sorts of oreoplatisms and tricks in pictures are not very useful, Zen is not enough, yes.

From this angle, it looks similar to E. testaceus, but somehow too small. Maybe there is a pronotum without glare?

Here is one

Ukraine, Rivne region, May 21. 6.5 mm.
Crypticus quisquilius ?

Help me identify the bug. Belarus. Minsk region 07. 07. 2017.

If it sits on currants - Agrilus ribesii. If not on currants - Agrilus sp.

good evening. A similar beetle has been identified as Microplontus millefolii (Schultze, 1896)
disconcerting is the shape of the top of the aedeagus, similar to Microplontus campestris (Gyllenhal, 1837)

Is it possible to identify a beetle from this photo ? Moscow region, 22.07.2017.

Krasnoyarsk Territory. Krasnoyarsk. The legs are black, the shape of the aedeagus, the notch on the front legs, and a number of other features led me to Hypera (s. str.) denominanda (Capiomont, 1868)

More precisely than Notiophilus sp. can you tell from this photo ? Moscow, 30.12.2017. In pieces of rotten stump, which brought home, found.

Notiophilus palustris

Notiophilus palustris

the lower legs are blackish in the photo-more likely to belong to the aquaticus group

Krasnoyarsk, mowing on a rocky slope. grassy vegetation. previously, I came across only Rhinusa antirrhini and only females
is it her own male or something from the "long-tailed" of the same genus? Edeagus is confused about something.

It may be Rhinusa neta (Germar, 1821). Thighs of all legs with a small clove. It seems to me that the tube does not taper to the top.
