Identification of beetles (Coleoptera)

Please help me figure out Elaphrus(s). Caught: 26.04.1999 Here: Moscow region Balashikha district, Zheleznodorozhny district, sandy bank of a stream.

good evening. Khakassia, Larch forest.
2. ground beetle 4 mm. The nails are not jagged.

  
... With the rest-everything is worse - this is from the Aleocharinae (like the tribe Aleocharini). It is unlikely that anyone will tell you at all.

good evening. Khakassia, Larch forest.
1. Selatosomus 13 mm. very similar to impressus, but slightly short in length. As a variant of nigricornis. The longitudinal stripe on the pronotum is clearly visible. Rear corner keels, clear and straight. The color is almost black. The punctuation on the pronotum is dense, on the shield sparse.

Well, with the ground beetle to the genus, everything is very simple-Microlestes. But then it is somewhat more difficult, but I will venture to call it 90% - M. minutulus Gz. There are not many species of this genus in your region, only 4. Of these, as far as I can tell from the image, only minutulus will fit in. But it would be better to pull the genitals

PS It seems that the brown color of the elytra is confusing, but you can't tell exactly from the photo whether this is a fact or an artifact of the shooting.
See for yourself, if the elytra are still brown, not black, and the antennae have brown main segments, then it may be a different species. Which one - we will discuss as a result of your inspection!

Batch # 10
All but 91, 100, taken in the vicinity of Krasnoarmeysk, Moscow region
95. 12.06.2009

95. Athous sp.

Please help me with the definition. It is very similar to Pterostichus (Morphnosoma) melanarius (Illiger, 1798). But I have very big doubts – the color is brown (lighter from below), the episternes of the posterior thorax are shorter and wider, the lateral edge (roller) of the pronotum is much thinner.
Western Ukraine, Transcarpathian region, Uzhgorod district, vicinity of the village. Nevitskoe lake.
5-6. 06. 1973
Length 15 mm

It seems to be similar to Abax (Abacopercus) carinatus carinatus (Duftschmid, 1812)

Thank you all! But this is not Abax... 3 bristle-bearing pores in the third gap...

Thanks! I'll check it out again tonight for melas. There are setae on the claw segment... And what kind of angles do you need? I'll try to do it.

I watched a series of my beetles.
We can say with high probability that this is Pterostichus (Feronidius) melas. On a cursory inspection, it really looks like Abax parallelus. But in Abax parallelus, the rib on the shoulders is arched.

Ptinus fur L.-you can also see 2 spots on the pronotum.

I've seen this before somewhere
