Identification of beetles (Coleoptera)

Well, if you find an opportunity, take a photo and post it. This information is interesting, we have Omaliinae come to light only by chance, and you may be able to determine your own.

I post: fees Yaroslavl, center, arrived on the DRL, built into the sidewalk.
No. 1-9.
10.13 No. 2-28.5.2012, were in the mass, but dry and of varying degrees of breakage...

#1-Arpedium quadrum
#2-really Acidota crenata

Arpedium does not surprise me - it is very willing to fly during the day and at dusk in fairly cool weather, and someone from the mass can sit on a lighted surface. But Acidota, maybe you have it as massive as Arpedium? Although we have quite a lot of it in Polesie, but in years I somehow did not catch it.

I can't say about the large number of Acidota in the city, I collect staffs on a case-by-case basis. I collected these species while studying the fauna of the museum's territory... And Acidota were massive - more than two dozen beetles were found on the glass above the lamp in a few days.

Chalcophora intermedia? Or is it Chalcophora mariana? What is the difference between these types?

Thank you.
Based on these images, therefore, it is impossible to determine.

Based on the analysis of habitats in the Kirov region exclusively - Chalcophora mariana

Ilya hi. at home, I'll look at my copies, maybe I have something similar. If not something special, it looks like Aphodius (Alocoderus) rufus (Moll, 1782)

The very top of the elytra is matte or shiny?

The very top of the elytra is matte or shiny?

due to the abundance of dots, it looks more matte than shiny.

I haven't defined it myself yet, just pasted it here

well, yes, so it seems to me. It seems similar. I have a male mine too. In general, I'll take a look at home after work. Although Alexey helped me a lot with him here. There is still some confusion in the names there are in some definitions.

Please define it. 07.06.12 Rostov region

Is it Leptura quadrifasciata? Mordovia, June

some Polydrusus as it seems to me. 4,5 mm. Krasnoyarsk, on the grass, bereznyak.
The claws are closely spaced. there are no teeth on the hips. The scales are rounded in shape and dark in color, sometimes forming small slightly lighter spots.

it looks like Aphodius rufus is there, at least in the Far East you can get to it, and aedeagus does not contradict this assumption.

Ilya, unfortunately, gave his own males for confirmation. There is only one female left, but svidu is similar to what you have. !!

Is it Leptura quadrifasciata? Mordovia, June

Krasnoyarsk, coniferous forest. about 9 mm.





2. 8-9 mm.

Leatherhead Megatoma sp., probably

I also believe that this is listoed

Leatherworm Megatoma sp., probably

confused by the lack of an eye on the forehead, the shape of the eyes with a notch and elytra some elongated, sharply narrowed nazad

I also think it's a leaf eater

yeah, Neophaedon pyritosus (Rossi 1792) turned out to be

can you tell me whose parts it might be? 4 mm approximately.

and it seems to me that this is from a shadowhunter like Orchesia

I think it's from a shadowhunter like Orchesia

so it seems to me that this is one of them.... Tomorrow I will check

Staff from Krasniyarsk-Quedius (Microsaurus) sp. No matter how you take pictures of it from different sides, it is difficult to move further, well, maybe "regional" would have taken it.

Both?

where can I download the DV determinant part 2 coleoptera, where there are 447 pages? Just what you need :-(

I think it's from a shadowhunter like Orchesia

Orchesia fasciata seems to have turned out. and also caught Serropalpus barbatus

Both of them?

Yes, both.

Both of them?

Genitals would be nice. The second one resembles mesomelinus, but I'm not sure about the first one, as a variant of xanthopus.
