Identification of beetles (Coleoptera)

Stenus sp.

Thank you very much!

say parts of the beetle belong to Salpingus ruficollis (Linnaeus, 1761).?

Any idea what bagous is?

tell me its distribution. In green it generally goes under a different gender

Ilya check for Bagous claudicans Boheman, 1845

tell me its distribution. In green, it generally goes under a different gender

According to the Palearctic catalog, S. ruficollis is found only in Europe (and in European Russia)

Any idea what bagous is?

Ilya, how do you deal with this family in general? I have "atypical" keys that do not fit into any keys
I think we should read more Europeans, their hydrobionts (in general) are more studied

So-so, but I figured it out a little. I also had some that didn't go anywhere, but then it turned out that I had overlooked it somewhere. If there is an edeagus, then it is not a problem to determine at all.

Dmitry, have you ever seen something like this in training camps ? In addition to ruficollis, I couldn't find anything suitable.

No, I didn't come across it. You should not be upset about the catalog, it has a lot of errors and shortcomings.

Zlatki (4 and 5 photos), from left to right:
Buprestis ?haemorrhoidalis - the first one in photo 4 and the first two in photo 5.
Dicerca furcata - the second and third in photo 4.
Buprestis novemmaculata - fourth and fifth in photo 4 and third in photo 5.
Melanophila acuminata-the fourth in the photo 5.

Krasnoyarsk, 5 mm, male, thighs not extended. The outer vein of the elytra is connected to the margin
of the Oedemera lurida?

For some reason, I think:
NN-lutulentus
SPb-puncticollis

Krasnoyarsk, 5 mm, male, thighs not extended. The outer vein of the elytra is connected to the margin
of the Oedemera lurida?

This size is either Oedemera lurida or Oedemera subrobusta. In many Oedemeridae, including this group of species, it is necessary to see the genitals for accurate determination.

some kind of nonsense is obtained. Maybe you need other angles?

Materials on fauna of Oedemeridae (Hexapoda: Coleoptera) in Latvia
1. Oedemera subrobusta (Nakane, 1954) & Oedemera lurida (Marsham, 1802)
I found a photo of genitals, like just Oedemera subrobusta.

On the Website http://www.coleo-net.de/coleo/texte/oedemera_me.htm just a photo of the genitals of this species is not

Most likely O. subrobusta
According to Vazquez's monograph:
Oedemera (Oedemera) subrobusta (Nakane, 1954: 180) (p. 172)
(= O. laticollis auct.)
Description
Length: 5.5-9.5 mm. Integument dark greenish or bluish.
Head short, strongly rugulose, eyes vaulted, not sinuate, antennae reaching about
elytral midpoint, last antennomere barely emarginate. Pronotum cordiform, short, anterolateral depressions well-developed, medial keel very faint to absent, surface strongly rugulose. Elytra finely and densely rugoso-punctate, long, scarcely narrowed apically (B/A 0.9 in both sexes), lateral margins not sinuate, sutural margins at most very slightly
sinuate. Outer costa joined to lateral margin posteriorly. Male metafemora not enlarged,pubescence on metatibiae very short and recumbent. Hooks of penis situated very close to apex (Fig. 110). Last abdominal segment of female as in Fig. 114.
O. subrobusta is very similar to O. lurida, but this has the hooks of the penis distant
from the dilated apex. Externally, both species are hardly distinguishable, the elytrapubescence is somewhat longer in O. lurida, the pronotum is longer, and the males have the metafemora very slightly enlarged. O. subrobusta is the O. laticollis of many European authors.l

Tell me, please, what kind of leaf beetle. It was found in the Moscow region on June 23.

Thank you for your help !

Please tell me what kind of leaf eaters are. Both were found on May 18 in the Moscow region.

The angle is normal, although their paramers usually stick vertically, just like the penis. Well, this is of course, as you understood, Oedemera subrobusta. It is difficult to distinguish them from Oedemera lurida by their external characteristics.

yes

the trouble with these heteromers... I think that this is a black-bodied bird-look at the genus Enicmosoma (Tenebrionidae: Lagriinae: Lupropini). They have just small sizes, pronotum with an uneven lateral edge, elytra in a tangled dotted line, 10-segment antennae with a 2-segment club and a two-lobed penultimate tarsomer. Quite a lot of them are described from Madagascar, but I do not have this work: ARDOIN, P. (1958): Contribution à l'étude des Ténébrionides malgaches. Le genre Enicmosoma Gebien. – Bulletin de l’Académie malgache (nouvelle Série) 35 (1957): 59–77.

Does anyone know anything about grinders?
Is it Xyletinus ?formosus Mannerheim, 1849

duc, Toscina. That's just the sadness.

Is it Xyletinus ?formosus Mannerheim, 1849
I would also say so.

Please help me identify it. Chalcosoma like, but what I don't understand. The size is like an atlas, but there is no small horn between the large ones in front. The length of the upper horns is clearly less than that of the atlas, the shape of the central one is different-smooth. I don't know where the instance came from.
