Identification of beetles (Coleoptera)

this if the outer rows without microsculpture are similar to palustris. substriatus is not available in the Moscow region. And I can't see the top of the nadcr-is there a lightening or a yellow spot?

Here is the same photo with lightened shadows. I don't see any special features on the top of the elytra.

the lower legs are blackish in the photo-more likely to belong to the aquaticus group

I see two setae at the end of the elytra - two pores

Platynus assimilis ? and ??
Belarus. Minsk region 11. 07.2017

assimilis is similar
to harpalus affinis probabilis

Tell me a couple of tricks.

Oba-Caucasus: Arkhyz, Dukka Lakes

The first one is probably exaratus, but is it normal that it is blue-purple? Maybe a subspecies?

Again, Anthonomus (Anthonomidius) dauricus Faust, 1891 ?
just over 2 mm. Anterior thighs with a small prong, the rest without a prong.
The hairs on the elytra are evenly spaced, without visible stripes.
Perhaps the shape of the aedeagus will help. Legalov identified a similar one as humeralis, but something doesn't look like it at all to me, and there are no stripes on the body and the teeth are not so powerful on the front legs.

welcome to the genus antonomus, where half of the species have approximately the same aedeagus

and so-yes, I would also call dauricus'om

Body length is about mm.
Upper scales are rather thick, elliptical, not hairy. Along the seam in wider and denser and lighter scales. Pronotum without obvious stripes of scales, with lighter ones in the middle and on the sides. The underparts are covered with broad light scales. Thighs of the legs without teeth. The greatest width of the pronotum is slightly in front of the middle. 7-segment whiskers. The legs and antennae are red. The head tube is red, long to the top almost does not taper, evenly bent. The eyes are not flat, protruding beyond the contours of the head.
As a variant of Tychius trivialis Boheman, 1843

Exaratus-s seem to be blue and should be. And the second one is similar to the Carabus (Tomocarabus) decolor. I would not like to make a mistake, I have the same ones listed as dekolors. I determined it myself

no, definitely not trivialis...
it's like T. tectus

The beetle is approximately 3.2 mm. It was collected together with Tychius albolineatus until now, and it was considered by me. Although it doesn't follow the shape of the aedeagus at all. The beetle itself is slightly smaller than the usual albolineatus and this male does not have a brush on the bottom of the thighs as it is in this species.
Pronotum in the center with a light stripe, but the scales are not of a different shape, but from the sides light stripes are formed by scales of a wider shape. The suture consists of light, more densely spaced broad scales, then faintly noticeable, but still lighter stripes alternate with less light ones through the row spacing. Hind thighs with a denticle, middle and front with a poorly noticeable denticle or tubercle hidden under scales. The underparts are covered with dense white broad scales. The head tube is practically not narrowed to the top, curved, rather long. The eyes are large, very slightly protruding (as it seemed to me).
I don't know about the view yet

no, definitely not trivialis...
It's like T. tectus

Ah, Tektus, there were plenty of them there, too...
Knocks down the sign light scales on the elytra...
Definitely him..by comparing it with others.

after all, this also turns out to be tectus?
such a large number of light scales on the elytra does not look like Tychius longulus Desbrochers, 1873?

Help me determine it.

interesting are those that are similar to tektus but with numerous light broad scales on top. Similar ones are defined by Legalovs as tektus..there I agree, according to the genitals of males, but there is a male whose apex is clearly pointed in a different shape...

Beetles slightly more than 2 mm. The color of the scales is yellow-brown. Similar in part to o stephensi, but confused by the shape of the head tube. It is more curved and slightly curved and tapering at the apex at the whisker attachment, but it does not look like the shape of melilotii. And the shape of the aedeagus is not at all similar to these two species. It is somewhat similar to Tychius breviusculus Desbrochers, 1873

And you think so too? Hm... can you help me determine up to the type of my Potokia, whom I supposedly identified as Kuprin? I'd really appreciate it.

Cats( Cat), what kind of perversion is lamiinam head forward to direct? This same deformity, plus, violates their morphological distinguishing features. In the photo lamia texture. And let me ask you, where do you catch textors in large numbers, and that they are completely different there? Photo to the studio. Lamia textor from morimus differs visually quite easily.

would Tychius junceus (Reich, 1797) be suitable? I don't know who else has aedeagus)

I went to this "trinity" according to the determinant, but something in the ratios of bodies got confused, and the distribution area was confused ))

The rather small Tychius is very similar to stephensi, but the tip of the aedeagus is confused, it is more evenly pointed. Also, the beetles are shorter and more rounded than stephensi, the head tube is evenly curved more than in stephensi, but not much, say, like in melilotii, and it is not narrowed to the top.. Thighs without teeth. The eyes, if protruding, are very weak. The aedeagus is narrowed to the top evenly, I would even say cone-shaped, not so sharply with a clearly narrowed top, as previously laid out in the form.

unless it is albolineatus and longulus and there is

well the first aedeagus clearly doesn't pull on albolineatus
1. aedeagus albolineatus

2. edeagus in my

Before that, I posted females, which I called longulus, and got a male. Edeagus unfortunately I don't know what it looks like in this species, but it definitely doesn't look like tectus!
The signs are similar. Thighs without a prong. But broad scales cover the elytra quite densely, especially along the suture and 5-6 aisles. In the male, which is darker, the scales are generally more evenly spaced. The eyes are very slightly protruding, the cephalotube slightly tapering towards the apex.

and the white sides didn't bother you?
Tychius medicaginis C. Brisout, 1862 is a classic)

Honestly - I don't know what it is

well the first aedeagus clearly doesn't pull on albolineatus
1. aedeagus albolineatus
2. edeagus at my

Unfortunately, I have no prepared albolineatus and nothing to compare it with, I also did not find any drawings of its edeagus, ...

Ilya, and then this can also be considered a white stroke on the side and this is medicaginis?
I literally called them before as junceus, because one in one with beetles that are similar in shape to edeagus with this species. Although these beetles together medicaginis and junceus were mowed down in one day from the same biotope.
This is hindered by the curvature factor of the head tube. It would not be bad to see just this sign.
