Identification of beetles (Coleoptera)

Good afternoon, forumchane!
Another question about staphylinids.
In the article "On the FAUNA of STAPHYLINID beetles (COLEOPTERA, STAPHYLINIDAE) in KAZAN" N. V. Shulaev, A.V. Bogdanov mentioned such beetle Trichoderma pubescens (Deg.).
Is it a synonym of Dinothenarus (Dinothenarus) pubescens (De Geer, 1774)?

It is necessary to look in the context-with what views it is next.
Po Pal. The catalog of Trichoderma is synonymous with the genus name Ontholestes. So it may well have once been used such a combination for the species Dinothenarus pubescens

Excerpt from the article table.
Subsem. Staphylininae.....

99. Staphylinus caesareus Ced.
100. S. dimidiaticornis Gemm.
101. S. erythropterus L.
102. S. ruficornis Bernh.
103. Trichoderma pubescens Deg.
104. Velleius dilatatus F.

In Tatarstan, it seems, everything is from lit. sources. And the legs of all this, apparently, grow from the "green", where virgo is in the keys. And who he might be is really a mystery. Something dark, with six dots in the dorsal row and dark legs, but not a nigrite... alternatively, furcifer, or maybe something else.

Thank you for the addition.
You are right about the "all from lit.sources". I'm trying to figure out who's who.
It is a pity that it is not available electronically in the form of Hydrophiloidea-Staphylinoidea (2 vols): Revised and Updated Edition, but thanks to Shavrin for the list of staphylinids of Russia. Very helpful.

So exactly Dinothenarus pubescens

In a good way, I would like to find a publication where this virgo is first listed, and see if the material has been preserved... And if you ask Shulaev?

Philonthus virgo (Gravenhorst, 1802) - Isaev A. Yu.was the first to indicate it, and only for Tartary. The neighbors of Chuvashia, Ulyanovsk and Samara do not have it.
I think, without checking, then the species was included in the "Cadastre of useful insects of the Republic of Tatarstan".
But I'll check with N. V. Shulaev.

Thanks for the tip-off. By trying to search.

This is out of the question. Otherwise, it would have been marked in the" catalog " as new for the Volga region. Are you sure you've been reading literature? At least in N. V.'s dissertation, this species is listed as "first noted for the Republic of Tatarstan ", and, as far as I understand, based on the materials of this dissertation, a work was published that is cited in the "catalog":
Shulaev N. V. Fauna of staphylinid beetles (Coleoptera, Staphylinidae) of the Republic of Tatarstan (Predkamye). The subfamilies are Oxyporinae, Steninae, Paederinae, Xantholininae, Staphylininae, and Tachyporinae. Annotated list of species. Kazan: Novoe Znanie CJSC, 2004, 32 p. (in Russian).
In subsequent works, Philonthus virgo was mentioned at least here:
Shulaev N. V. Ecotopic distribution of short-winged beetles (Coleoptera, Staphylinidae) in the Raifa forest // Proceedings of the Volga-Kama State Nature Reserve. Issue 6. / Under the general editorship of O. V. Bakin and Yu. A. Gorshkov. - Kazan, 2005. - pp. 254-264.
and here, and again as a new one for Tatarstan:
Shulaev N. V., Bogdanov A.V. To the fauna of staphylinid beetles (Coleoptera, Staphylinidae) of the city of Kazan. The cauldron. un-ta. Ser. Natural sciences. sciences. - 2008. - Vol. 150, book 1. - pp. 121-125.
And this is only from what I found in the rubble of literature. But please specify, of course, otherwise it's interesting who is hiding under this name.

1, 5, 8-yes, like gallicus
2-yes, it seems even the usual piceus
4-Tetartopeus, which one-I can't tell from the photo
6-Anotylus, as an option the usual rugosus
7 - Scopaeus, according to the photo-not an option
10-I think yes. 9 may turn out to be its female. 3 - if healthy, then it can also be one of them.

North-west of Ukraine, June 4. Road in the middle of a forest clearing. This is Poecilus, isn't it ? Can I get to the view ?

if we assume that there is a tooth on the shoulder, then I would say that it is versicolor

Saratov region, May.
1. Agapanthiola leucaspis ?

2. Glischrochilus hortensis?

3. Cantharis rustica?

4. ?

5.?

Saratov region, May.

1. for me so Agapanthia violacea / intermedia
2. yes
4. Malachius aeneus
5. Amara? similata (female)

1. Agapantiu on the side would be necessary, intermedia is quite common

Saratov region, May.

3. Cantharis rustica?

I think Cantharis pellucida Fabricius, 1792

Tell me, what kind of animal?
China, Weihai.

post it on iNaturalist.org (and others will benefit)- it's not difficult - just fill in all the fields honestly, including the level of understanding of the name-squad, family,subfamily-no more, if you don't know, they will sort it out as much as possible, especially barbels - they look just through filters - they find it faster.
everyone is also "touched" by labels with minutes and decimal seconds - "up to a centimeter", and working with them in modern services will be inconvenient for you - recalculate and enter manually... go to decimal degrees already - with adequate accuracy.
