Identification of beetles (Coleoptera)

Please help me identify it. Aphthona lutescens ? Moscow region, 26.08.2018.
P. S. Lythraria salicariae is still similar.

not afton, if the dotted lines are collected in rows. Litraria - really similar.

Dear etymologists, Once again, I have to ask you for help. Is it possible to identify elephants? Material from the stomach of the robin (Erithacus rubecula), 18.04.15. Same region: Rogachevsky district, Gomel region, Belarus.
The dimensions of both heads together with the head tube are ≈ 1.5 mm.
Together with the heads, the material contains 1 prsp. (its dimensions: width ≈ 1.6 mm, length ≈ 1.3 mm), fragments of elytra (length of the largest fragment ≈ 2 mm, width just over 1 mm), limbs (length of the thighs and shins from the photo ≈ 1.3 mm).
If it is objectively impossible to identify beetles, please indicate this to me.
I express my gratitude in advance!

The second head tube belonged to Magdalis (s. str.) - most likely one of the following trio: violacea / duplicata / frontalis

First... definitely one of the Entiminae with lateral whiskers and a developed epistome. I think the most likely one is Sciaphilus asperatus

Another elephant from the food of the robin (Erithacus rubecula). 27/05/16 Kamenetsky district, Brest region (territory of the National Park Belovezhskaya Pushcha).
The length of the head together with the prsp. ≈ 1.5 mm. The elytra is 1 mm wide and 2 mm long.
Maybe some Ceutorrhynchidae?

last type trechus gravidus

1-no, this is from the real Peryphus. Most likely, something simple, but this is not the group that should be identified from the photo.
2-this character is from Sinechostictus, most likely nordmanni (Chaudoir, 1844)
3-I said Trechus type quadristriatus
4-no, not lampros. This is someone from Philochthus, as far as you can see
5-and this is yes, Metallina, it seems even properans
6-I would agree

and the 3rd can be Bradycellus curtulus ?

Good hour forumchane!
In literature Lebedev A. G. " Materials for the fauna of beetles (Coleoptera) Kazan province. Proceedings. Russ.Entom. Obshch., St. Petersburg, Volume XXXVII, 1905. on page 359, the species is Bembidion ustulatum. On the site insecta.pro there is no such name. Please help me figure it out. Does such a slider exist, or is it a synonym?
And another mysterious friend - Bembidion rupestre.

The first one is easily located in the Catalog.
The second one is not in the Catalog, but who is the author of the name?

Thank you very much.
What kind of directory do you use?

also in this literature "Lebedev A. G." Materials for the fauna of beetles (Coleoptera) Kazan province" there are these types:
Platynus gracilis Gyll.
Platynus 4-punctatus Deg.
Platynus ruficornis Goeze.

Please tell me what their current name is.

These names of the same beetle Platynus marginatus L.-Adopt marginatum L. ?

under the name "ustulatum" usually tetracolum was given, so you need to look. About rupestre Ilya has already answered

and the 3rd can be Bradycellus curtulus ?

No, it can't.

Hello! Please give advice on the species of beetle?
Russia, Kazan.

Good day! Is it impossible to determine the "Kazan" Pterostichus before the species?

Thank you very much.

Sericoda quadripunctata (Degeer, 1774) = Platynus 4-punctatus Deg.
Paranchus albipes (Fabricius, 1796) = Platynus ruficornis Goeze
that's what Platynus gracilis Gyll., I do not know, maybe Agonum (Europhilus) gracile Sturm, 1824

Ilya, could you take a look at the elephant at the end of page 617?

Missed it, yes.

Will it be possible to determine such a small (three or four millimeters) staphylin ? They were sitting on the open windows. Moscow region, 06.09.2018.

1. Acilius sulcatus ? It seems to be similar, but the pattern between the eyes is different.

2. ???

3. ???

and there is no top? at first glance, some kind of Gyrophaena.

Not from above. Here's another shot of the same bug. I almost straightened my belly, otherwise they kept holding the whole belly like a curved bagel all the time. Like the bug on the left in this picture.

You can probably sign it as Gyrophaena sp. All the same, neither the sculpture nor the lower abdomen (especially since it is most likely a female) is visible. In general, they are best opened, because several species can sit on one mushroom at once. Their aedeagi, fortunately, are very specific in most cases: http://www.coleo-net.de/coleo/texte/gyrophaena.htm

Thanks for the explanation.

Please help me identify it. Moscow region. 06.09.2018.

1. Acilius canaliculatus, female.
2. Colymbetes paykulli.
3. Hydrobius fuscipes in a broad sense.

And here is who approximately (from podberezoviki, okr. pos. Vostochny, Moscow)? Of the redheads-are there two types, or just some lighter? Is black a different species, or a morph? I'm sorry, there is no photo, but there is no access to the material right now, maybe you just know the characters.

black-Oxyporus mannerheimii
others, I believe, Oxyporus rufus

black-Oxyporus mannerheimii
others, I believe, Oxyporus rufus

well, yes, in the European part of the choice is small.

Is there such a beetle as Amara harpaloides Dejean? Maybe it's a synonym?

Curtonotus harpaloides (Dejean, 1828).

Thank you very much.

Another confusion for me.
On the website https://insecta.pro/taxonomy/1017261 The species listed is Harpalus subcylindricus Dejean, 1829.
In the "Full name"
column, Harpalus (Harpalus) subcylindricus Dejean, 1829 = Harpalus subalbanicus Puel 1938 = Harpalus avarus Schauberger 1930 = Harpalus pumilus Dejean 1829.

On the website https://species.nbnatlas.org/species/NBNSYS0000007408 Harpalus vernalis (Duftschmid, 1812) (accepted name Harpalus pumilus)
HARPALUS (HARPALUS) PUMILUS STURM, 1818.

Isaev A. Y. "Beetles of the Forest-Steppe of the Middle Volga region" has both Harpalus subcylindricus Dej and Harpalus pumilus
. Who does Harpalus pumilus belong to? Please help me figure it out.

1. Acilius canaliculatus, female.
2. Colymbetes paykulli.
3. Hydrobius fuscipes in a broad sense.

Will you be able to identify the larva ? Caught in the same puddle as Colymbetes paykulli and Hydrobius fuscipes, as well as Dytiscus circumcinctus (isn't that him in the second picture ?) Moscow region, 07.09.2018.

The larva is Acilius sulcatus.
The beetle is more like D. marginalis, but of course you need to look at it from below.

Is it possible to determine the species or genus from the image?

Look not only at the name of the taxon, but also at its author (they are not listed for nothing). Harpalus pumilus Sturm, 1818-valid species, formerly vernalis. Harpalus pumilus Dejean, 1829-synonym of subcylindricus and junior homonym of Sturm's species. I.e. pumilus in Sturm's understanding and pumilus in Dejean's understanding are not the same.
This, by the way, is why I'm not sure about the synonymy of Platynus gracilis Gyll.
