Identification of beetles (Coleoptera)

Help me deal with staphylinids
I understand that most of the species are not defined and photos are not very good, but I would like to see the genus

1-yes, Arpedium quadrum
2 -?Gabriel - nothing is visible
3-Q. cf. xanthopus
4-S. cf. testaceus
5-yes, Lathrobium-looks funny, I don't understand who is
6-Cyllodes ater

  
I have another question - how to distinguish a pair of ground beetles from Paradromius-longiceps/suturalis?

I didn't find any tables where both types are present. But P. suturalis is in the DV determinant, you can try to look it up.

I tried it, looked at it. It seems that there are differences in color, but they wag, and I have half of the material - in the light, and there are immature copies... Need differences in structure, where would you know them?

Try to write a personal message to Igor Solodovnikov (on the I. Solod forum)

Please help me identify these small beetles.
1. Cyllodes ater ?
Moscow, June, on the tinder box laetiporus sulphureus.
Length - 4 mm.

2. Moscow, June, on the tinder tree laetiporus sulphureus.
Length - 3 mm.

3. Chekhov district, Moscow region, July
Length - 3 mm.

4. Moscow, July
Length - just over 2 mm.

5. Moscow, June



Length - 2 mm.

And here is this handsome man, apparently a close relative of No. 4 from the previous post.
Collected in the south of the Moscow region in the Serpukhov district (road in a pine forest in the vicinity of d.Luzhki)
Length-approx. 2 mm

"Maybe I should scan them somehow, but no?"
- Without being afraid to appear smart - I dare to advise you to look in this dark forest - at the end of the page there are several links: https://www.zin.ru/ANIMALIA/COLEOPTERA/RUS/inconi.htm

Please help me identify these small beetles.

1-yes
2-Eledona agricola, almost a monophage on this mushroom
3 - Anisotoma cf. castanea
4-Brachypterus cf. urticae (a beetle from Serpukhov too), there are not many of them, check the table. Here, for example: http://coleonet.de/coleo/texte/brachypterus.htm
5-Kateretes, look up the keys on the same site

Just immature ex., just such on the light and rod. Judging by the antennae, a lineatocolle/fulvipenne pair is likely, the second type of light is definitely approaching.

That immature - no options, about the " rod " is probably where as... On the Volga, flavipes fly en masse to the light, and I don't even remember catching red wings like that

I have another question - how to distinguish a pair of ground beetles from Paradromius-longiceps/suturalis?

I think I'll join the question...

They gave me a beetle. Collected in the KCR. Elbrus region of Gudgora 1.7.21 L-6mm Checked by its determinants found nowhere

Pedilus of some sort

Interestingly, and Melirids/Small/Soft-bodied animals are not related to these Pyrochroids?, "they're too much alike."

Interestingly, and Melirids/Small/Soft-bodied animals are not related to these Pyrochroids?, "they're too much alike."

The families Melyridae and Malachiidae (which some taxonomists consider not to be an independent family, but only a subfamily Melyridae) belong to the superfamily Cleroidea, and the family Pyrochroidae belongs to the superfamily Tenebrionoidea, and both of these superfamilies belong to the same infraorder Cucujiformia.
And the family Cantharidae belongs to the superfamily Cantharoidea, which belongs to another infraorder-Elateriformia.

This is very unlikely. Take a look here: https://www.biodiversitylibrary.org/item/45...ge/395/mode/1up
There is a certain P. errans from Dagestan (Shahdag): https://www.biodiversitylibrary.org/item/46...ge/359/mode/1up
This is probably it.

Hello! Please help me identify the beetles. Thank you for earlier!

The first four photos (from top to bottom):
Harpalus affinis
Denticollis linearis
Poecilus lepidus
Harpalus (Pseudoophonus) rufipes

I read in ZIN-e that 9 species of this genus are registered in Russia, but I lost this page, and I don't remember if P. errans was there . Mongolicus, of course , is implausibly somehow associated with the KCR.
Now I looked at the nature of Shagdag - in principle, it is not similar to the treeless alpine areas of the KCR. The only thing is that Dagestan has a drier climate. And I'm pretty sure the beetle wasn't picked in the woods.

Thank you for your help.

Is it possible to identify this dromius da species.
Collected on 19.3.22 in the Chekhov district of the Moscow region under the bark at the base of the trunk of a shrunken spruce.

May. BUT you need high-quality photos of the head and elytra (at least one)

Hello! Is this Rhamnusium bicolor (Schrank 1781)? Caught in February of this year in a production heated room. European part of Russia. Thank you for earlier.

In my opinion Arhopalus rusticus

Thanks! Came to the conclusion that it is this view.

I tried to re-shoot it, but it turned out, unfortunately, about the same. Apparently, we need a microscope, which is not yet available.
The beetle is 7 mm long.

Hello everyone.
Is it possible to determine phyllobius from such a photo (circled in red)
Belarus, June 2020, if I understood correctly - by mowing blueberries.

Duc Makulikornis, no? Although maybe Pomaceus, probably more likely the second, but this is not accurate)
Mutilida you have there interesting, zhiirnaya, hot soup with her cook, is there in other angles?

ENO!
I congratulate you on the anniversary 7609 message on this forum! As always, it is succinct, informative and appropriate.

PS
Sasha, I answered your email, gave you a phone number, at least call me.

Please help me identify these small beetles.
1. Very small staphylins. Collected on a tree mushroom on a linden tree on June 18 in Moscow.

[attachmentid()=334172]

4. This Bembidion sp. is it possible to determine up to the type of view from the photo?
Collected from an exposed patch of dry soil on the edge of a mixed forest.

5. It is very interesting that this is a black beetle with red legs, whiskers and mandibles.
Collected on July 12 on a road in a pine forest in the village of Luzhki, Serpukhov district, Moscow region.

2-3. Ciidae. such photos are not even worth guessing
5-Kateretidae possibly the genus Bracypterolus sp.
6. Phaeaphodius rectus

Please help me identify these small beetles.

1 - most likely, Gyrophaena boleti. If the fungus is Fomitopsis, then it probably is
4-B. (Metallina) lampros / properans
5-again Brachypterus cf. urticae
