Identification of beetles (Coleoptera)

1. Calathus sp. size is unclear

1. Dolichus halensis

Please help me with the definition.
Collected in early August in a window trap in the south of the Moscow region.
Length-approx. 4mm.

Small leiodidae, 1.5 mm
Liocyrtusa?

Like Brachygluta, but it won't go any further

Cheburashka?

yes, it seems to be, vittata as an option

probably haematica

well, yes, in the sense of hydrobius

just vittata and comes out
on Brachygluta strongly also thought that haematica, but it is confusing that there are no tufts of hair behind it on top of the belly. The Germans write about this for some reason, like in their own key.

So what's her gender?" If the female (and judging by what you can see in the photo, it is), then there should not be any hair bundles there.

In Stavropol flies to the light 14.8.22 L-5 mm Berosus ?

Please help me identify these beetles from the Moscow region.

2-habitually some kind of Corticarina. If the male (front tibia with a prong), then it is better to tear off the genitals
3-except for Colenis immuna, nothing comes to mind.
4 - ?Olibrus-see the suture grooves
5-Microplontus. Not from tansy, by any chance?

Microplontus is most likely really from tansy. There is a lot of it in this meadow and I mowed it on purpose. I still hope to collect the tansy leaf beetle, but it's probably too early for it (as far as I understand, the beetle is late).

We drove kefir from RSO-A Mamison meadow about H-2500m and there is a bug 2.2 mm how it survived in this state is just a miracle

May, Saratov region
Amara aenea?

Anthrenus flavipes?

Please help me with the definition. Beetles were collected at the end of August in a dry meadow in the Chekhov district of the Moscow region by mowing tansy.
2. Length-2mm.

May, Saratov region.
Oenopia conglobata?

?

Pseudorchestes ?pratensis.

I looked up the keys for this genus on the website of I. A. Zabaluev. It says that most of the species are monophages and food matters when determining. Tansy is given for Pseudorchestes circumvistulanus (Białooki, 1997).

Please help me identify the bark beetle. Collected in a soil trap on the steepened slope of the southern exposure in the south of the Moscow region (Serebryano-Prudsky district).
Length - 2.3 mm. Long white pubescence.

the photo is so-so, indeterminate
BUT compare with this https://www.zin.ru/ANIMALIA/COLEOPTERA/RUS/thapetza.htm

Colleagues, please tell me your family. Something nothing comes to mind There was a version that Xyletinus, but after comparison with whole beetles, the assumption was not confirmed. Moscow, elytra length 2.8 mm.

It looks like some kind of Magdalene elephant.

Prosternon tessellatum?
Saratov, May.
