This is rather a Polygraphus polygraphus, which Evgeny forgot about.
Females also have bristles of hair on their foreheads and are longer than those of Polygraphus subopacus. And the club of the antennae is pointed, while in Polygraphus subopacus it is rounded.

Still, I don't agree. I am inclined to believe that this is just P. proximus, yet females of P. polygraphus do not have such a pronounced and thick brush of hairs on the forehead, as mentioned in Chilakhsayeva's works. Review of species of the genus Polygraphus in the fauna of the Moscow region, 2010. Catherine also has a strong suspicion that this is exactly the Ussuri, especially as I understood, at one time a hearth of just this type was discovered nearby.
By the shape of the mace I agree, this once again shows that subopacus can be ruled out.

I will not argue...

especially since the subject of the dispute is missing and P. proximus, which I do not know.

Our discussion once again proves that it is impossible to reliably determine such a trifle from a photo!!!

I want to finish off the Kislovodsk beetles. With elephants, leaf eaters, barbels and others, I managed on my own, but with the beetle I have big problems and need help.

1. Amara ?ovata - 9.3 mm, Kislovodsk, park, July.
2. ?Zabrus ?tenebrioides, if so, which subspecies? - 15.5 mm, ibid
. 3. Bembidion by Isaev I go confidently to (?Peryphus) ?tetracolum Say, 1823, but then Wed. Volga region, and this is the Caucasus... 5.2 mm, Narzan Valley, together with the B. cyaneum series

3. so bembidionov define full shamansivo-but I will assume that it is but not sure 50 % even Bembidion (Peryphus) cruciatum quadriflameum Rtt., 1889

1. A. ovata f.adamantina Kolenati 1845

2. Zabrus (s.str.) tenebrioides longulus Reiche probably it.
