Identification of beetles (Coleoptera)

Hello! Is it possible to identify at least a number of beetles from these photos? I would be very grateful! Beetles were caught in the Tyumen region, summer (June-August), mainly in the south of the region (Ishim district and neighboring areas).

Bad Den, smax, thank you so much! I wanted to ask about cryptocephalus (which is on 01 and 01-2). I found C. frontalis and C. ocellatus using the determinant. The problem is that the frontalis seems to have a yellow anterior edge of the pronotum and a spot on the scutellum (unfortunately not). On the other hand, ocellatus doesn't seem to have yellow epipleurs, but mine does. Can it be one of these types?

In blacks, it is very desirable to see the forehead. Somewhere there was an audit on them....

Is it Gonioctena decemnotata ?

Thank you all very much! I will look at his forehead today, it is black and yellow (that is, the face is almost all yellow, and there is a black pattern on the forehead).

the pedophile bug

What kind of family is this anyway? I didn't catch any of them. Staphylin?

of course, Sepedophilus sp.

Was his belly bitten off, or is that what he is?

Mowing, settled meadow. Approx 2 mm. The head and elytra are darker, the legs and antennae are reddish-brown. Head and pronotum in thick raised and pressed scales. Spaces on the elytra in light broad pressed scales, also with a number of protruding long scales, club-shaped, expanding towards the apex. Pronotum transverse. Thighs without teeth, claws close at the base.

Sepedophilus bipunctatus

Brachysomus echinatus (Bonsdorff, 1785), common species

why not Sepedophilus wankowiczi (Pandelle 1869)?

"Flügeldecken ebenso wie der Hinterleib an den Seiten mit langen schwarzen Borsten besetzt."

ocd. Krasnoyarsk, Sosnyak, glade, mowing.
approx. 3 mm. Elytra in strongly dissected scales, do not form stripes and spots. In addition, raised long hairs. Pronotum not wide, evenly rounded, narrower than the elytra. Is this Hypera nigrirostris ?

seaton. 3 mm. Elytra with rows of long protruding, arranged in rows of hairs. The head tube on the top is biconvex, shiny with light scales. In the middle with a deep groove. The eyes are moderately prominent. Pronotum not transverse with large dots, on the sides of the stripes with light scales. Odd row spacing has indistinct spots of lighter scales.
macularis?

Sitona lineellus (Bonsdorff, 1785)
most likely
, at least because there is no macularius in Siberia

Ilya thank you, confused by the fact that the hairs on the elytra are well developed throughout and quite long.
Do you have Hypera (s. str.) transsylvanica (Petri, 1901) ? I found one beetle in the collections similar in description
