Identification of beetles (Coleoptera)

Hello! Please help me identify coleoptera. Filmed in Belarus.

The idea suddenly came up. And, you know, very similar.
Look at this -

Good new year, dear experts!
Please help, again with my guests.
Moscow, winter, January, ceiling, apartment

Thank you in advance for your patience with amateurs

A new genus for the fauna of Belarus! Write a note before you get ahead of it.
   
I think it's Margarinotus brunneus (=cadaverinus).

If possible, help identify the elephant. North of the Omsk region, forest zone. 12.05.14. On a willow tree, 8-10 mm.

Dear forumchane! Please tell me if I correctly identified the dead eater. North of the Omsk region, forest zone. Early July, 15-17 mm. Please excuse the quality of the image - I took it with a regular soap dish.

Silpha_tyrolensis does not live in Russia look for pm among other species of the genus or look in the direction of aklipei

Dear forumchane! Please tell me if I correctly identified the dead eater. North of the Omsk region, forest zone. Early July, 15-17 mm. Please excuse the quality of the image - I took it with a regular soap dish.

Most likely, this is an under-colored Silpha obscura Linnaeus, 1758, although the color is certainly similar to Silpha tyrolensis Laicharting, 1781. It is unlikely that S. tyrolensis occurs east of the Carpathians, although, yes, there are reports of 2 specimens. from the Voronezh region. But ex. The one scanned for the Red Data Book doesn't quite look like tyrolensis-it's more convex.

If possible, say something about the bronzes in the photo. The first four are from the north of the Omsk region, from the forest zone. The last one from Naberezhnye Chelny. The size of the fourth is about 30 mm.

Please help me identify a pair of gold coins. North of the Omsk region, forest zone, end of June, about 25 mm.

Please help me with a few barbels.

5. Kyrgyzstan, Bishkek, 30.05.1994 length 11mm

Can you tell me if this is Rhagium sycophanta (Schrank, 1781)?
Ukraine, Kharkiv region, Kolomaksky district, oak forest near the village of Nagalnoye. 01.05.2014.

Silpha obscura is not found here at all, they come across to the south. Last summer, out of one and a half hundred dead eaters caught in traps, there were 4 copies as in the photo, the rest are Silpha carinata and Phosphuga atrata. But it is difficult to confuse them with the dead eaters in the photo. Maybe there will be some other suggestions.

This ribbed thing I would call Buprestis strigosa

Silpha obscura is a very widespread and highly variable species. The beetle in the photo looks exactly like it (as far as you can judge the sylphs from the photo at all).

And isn't it the same thing: Taiga coniferous gold leaf = Buprestis strigosa = Buprestis novemmaculata.

In Silpha obscura, the elytra and thoracic shield are usually the same color, and the difference is clearly visible in the photo, as in Silpha tyrolensis. See the link http://www.galerie-insecte.org/galerie/Fam_Silphidae_02.html

Please help me identify leaf beetles. All from the north of the Omsk region, forest area. And one small ground beetle 6-7 mm from the same places.

No, of course not. Spit on these Russian names, and so much confusion of any kind.
Buprestis strigosa Gebler, 1830. No one has reduced this taxon to synonyms, and the rank to subspecies has also not been reduced. Judging by the Palearctic catalog, at least.

In the case of Silpha, the color of the beetle is absolutely not important. Normally, they are black. Sometimes they give brown or even bicolored forms (these are not necessarily juvenile individuals). These forms have no taxonomic significance and can never be used as a defining feature.

This is Plectrura metallica, as far as I can see. He lives in Japan and on our Far Eastern islands.
Identifying barbels without labels is a very thankless task. Fake labels are evil, not just a misunderstanding, alas.

3. Kyrgyzstan, Bishkek, Chon-Aryk, h=1400m 22.05.1996 length 22mm

female Dorcadion optatum mathiesseni, if so.

Surroundings of Kirovo-Chepetsk, Kirov region. June 10.
Brown nutcracker-Sericus brunneus (Elateridae)?

Dzerzhinsk, Nizhny Novgorod region. Length 8-9 mm, June.
Both Chrysolina sturmi ?, male and female?
