Identification of beetles (Coleoptera)

Please help me identify ground beetles caught in the KCR, the place of capture and date are visible on the labels. On plants.  

1, 4-Poecilus sp.
2, 3-Agonum seems similar to sexpunctatum, but not sure

And on khrushcham it is possible to assume something....?

13 similar to Homaloplia sp.

By the way, according to ZINA's website, Dapsa horvathi is distributed in Russia from the Altai to Primorye, and Dapsa trimaculata - in the south of the European part. Maybe in the Crimea? horvathi and not, but only D. trimaculata?

Possible, but unclear copies. they are found, for example, in our Volga region, in a word, everything is not so simple with them, yes, in the Crimea, trimaculata

Well, we already figured out about the checklist And are you sure that aterrimus, and not elongatus? For the Rostov region, it is common, but about aterrimus ...

Of course, I'm not sure... according to elongatus, I don't have anything for diagnostics...
By what criteria can they be divided?

This elephant "came" to me yesterday.
Caught in January, Egypt, Nile Delta.
Can't you tell me anything about it?"

Guys, and on my weevil does not work out anything? Maybe I should move it here:

Background:

Determined by Jacobson, went to the genus Limonius.

Zabl in google - from similar found only this on bugguide:



Near The Curlew Lake, ~10 miles Norrtheast of Republic, Ferry County, Washington, USA
May 22, 2008

Limonius venablesi

Based on comparison with the Wagner/Scott Collection.
… Dennis Haines, 5 June, 2008 - 10:23am

Actually, ofigel (there is no such type in any lists). But then I noticed that my spots are the opposite-long on top, short on the bottom. Either it's not a limonius, or it's an American in our garden. Here I took a picture as best I could, help!



Western Siberia, near the forest, vegetable garden. 9mm

Maybe it's Ludius boeberi

If according to the European identifier-it says Ludius 17-23 mm, large. BUT the prong is on the hip. tires are available.

Size is not a feature, but in addition to the features, especially since I understood from European that there is only one species in the European part, nothing prevents other species of the genus from being larger or smaller, especially from Siberia.
It is common practice not to include features in the qualifier for species that do not occur in the territory of the region for which the qualifier was compiled.

I poked around in the Net, like Ludius = Elater, maybe there are some experts on nutcrackers, they will say more precisely, especially since the bug is so noticeable, and not as usual gray or black

Anostirus boeberi (Germar, 1824) - identified from the DV with a tip from Alekseyev Kovalev and Sazhnev

Please help me identify and decide. I suspect that all the photos of D. circumcinctus are male and female. After the photo of the front side, the underside of the same beetle is presented. Beetles caught in the Leningrad region.Priozersky district, villagePriladozhskoye (ponds). Many thanks to Evgenich for the copies provided.    

In my opinion:
1-4-D. marginalis
5-6 - D. circumcinctus
7-8-maybe D. lapponicus is like this.
But, of course, photos of basins are more necessary.

Please help me identify and decide.
7.
8.

In my opinion:
7-8-maybe D. lapponicus is like that.

No, it doesn't look like D. lapponicus . The yellow border of the pronotum is usually much wider, whether in the female or in the male. Still would find out the size, lapponicus is relatively small...

Anostirus boeberi (Germar, 1824) - determined by DV with a hint from Alekseyev Kovalev and Sazhnev

this is indeed Anostirus boeberi . at Chkerkpanov, it still goes as Corymbites. The color of the elytra is diverse. I have forms without spots. with long stripes, almost black and like this. Cherepanov has a lot of subspecies listed there.

I also had an idea about lapponicus, but was confused by the size... And so it is very similar, lapponikus often have melanistic specimens, they have a narrow border on the pronotum... I have quite a lot of them, if you are interested, I can take a picture and post it...

Posted a photo of lapponicus-melanist in the theme Water beetles in images...

I came to lapponikus by the method of exclusion, I did not hold any beetles of this species in my hands. But confuses, of course, and the narrow border of the pronotum and the size of 37 mm. I give up.

I also had an idea about lapponicus, but was confused by the size...

Or maybe there's something wrong with the size? Still, 37 mm, to put it mildly, is too big for lapponikus ...

I looked it up in Lapponicus Melanist's Water Bugs. But it's very similar! It is necessary to specify the size!

Please help me with the floater. Arrived at the light of the DRV in August, Mikhaylovka, Volgograd region. Size 3-4 cm.

Well, that's it, Dytiscus dimidiatus.

Hello, tell me what kind of beetle, at least the family. It is about 8 mm long. The formula of the legs is 5-5-4. Us. threadlike, starting under the side edge of the head. Pronotum without acute lateral margin, narrower than the elytra.
Head with a sharp constriction and swollen temples. Elytra slightly expanded back. The claws are simple, not split. Stuck between the spangles of the Anticidae and the Pyrochroidae flamethrowers.
There is something similar to Pedilus, but I have never seen this beetle....

Similar to Pedilus. In the evening I will try to post a photo of someone I think is Pedilus.

Please help me with aphodium.
Place of collection-Kostroma region, Manturovsky district, Unzha River bank.
Shetinki on the legs are equally short, the elytra are black with a slightly reddish shoulder protuberance. Size 4 mm. According to green, it was determined to Aphodius lgockii, but the area indicated there - Polesie-is very confusing... it's going to be a long way off...

to Stavropolez:
1-Amphimallon solstitiale
2-Rhizotrogus aestivus
3-Miltotrogus (or, if you want, Holochelus) aequinoctialis
4-Anisoplia campicola or zwicki
5, 6-most likely the same Amphimallon solstitiale
7-Chaetopteroplia segetum
8-Anisoplia deserticola
9, 10 -?Phyllopertha horticola
11-Chaetopteroplia segetum
12-most likely Anisoplia austriaca, or again Anisoplia campicola or zwicki
13,14-Homaloplia sp.

I will duplicate my post # 9405 from the main topic here just in case
(otherwise they may get "lost" there):

Andrey, why is Phyllopertha chorticola under ? - for me, it's

Tell me who it is I apologize for the quality.

Andrey, why is Phyllopertha chorticola under ? "she looks like it to me."

It is, of course, only: a) I don't remember what Caucasian Blitopertha looks like b) should a person posting beetles independently check the definitions and dig into the determinant?

1. Cassida sp., something familiar-rubiginosa like
2. Cryptocephalus probably aureolus
3. 4. Monochamus sutor
5. Coccinula quatuordecimpustulata

Still galloprovincialis-did not guess (between them I thought just))) Thanks

Cryptocephalus sericeus - in my opinion, the beetle is small enough even for sericeus, although the edge of the pronotum is not visible, but it feels like it's not S-shaped - I think it's something from genitalnyh

 
3. 4. Monochamus sutor

Nope - this is Monochamus galloprovincialis

aha

I saw that I was late and decided to" re-answer "

Of course, I'm not sure... according to elongatus, I don't have anything for diagnostics...
By what criteria can they be divided?

In years I do not remember! They differ habitually well. Now I'll look for elongatus images and attach them (although there are some on the web!)
And aterrimus is right here http://macroid.ru/showphoto.php?photo=25746
Pronotum and proportions!

Thank you very much!

I have in one collection, in my opinion both types. Yesterday I compared two females ... they look very different. 1) gaps above the cr. slightly convex, discal pore-pits over the cr. large (approximately equal to the width of the gaps); the main indentations of the prsp. slightly dotted, rather wrinkled; posterior corners of the prsp. they don't stand out at all – they are widely rounded (apparently aterrimus) 2) spaces over the cr. strongly convex, discal pores-pits over the cr. medium-sized (half the width of the gaps); the main indentations of the prsp. are densely and strongly dotted; the rear corners of the prsp. are widely rounded, but laterally. prsp. before the corners slightly indented (barely noticeable) – as I understand it, this is elongatus.
Both have very long (and narrow) hrh episterns.

yandex. disk photo of the ad code. and the basis of the prsp. (the quality can't be improved ):

1.1

1.2

2.1

2.2

Acilius (s) should be viewed from below. In A. sulcatus, the posterior thighs are darkened at the base, the first visible part of the abdomen (ventricle) is black, and the rest are only with yellow spots. However, the female has another reliable sign: the pronotum is on the sides with densely hairy depressions. And in A. canaliculatus, the hind thighs and this same ventritus ( ) are yellow. In the female, the pronotum is without hairy indentations, or they are barely noticeable. And besides these two species from Acilius, we have no one else.
By the way, these are still far from small swimmers. For them, an ordinary hand-held magnifying glass is enough, why a microscope? I would say very large ones. Here is Laccophilinae, Hydroporinae ( ) - this is yes!

By the grace of God Almighty
And pressures of marketplace ©
And thanks to the help of Dmitrich,
both Acilius were identified as sulcatus
and placed in the water beetle branch
