Did Medvedev see them for sure?

16.04.2008 12:07, omar

I doubt he saw them. Judging by the reviews, he is a very attentive person, a great connoisseur and lover of his craft, who does not miss unusual beetles. Maybe it was not the same Medvedev, but, for example, the current president, and it was shown to him?

In fact, blaps have wrinkled elytra - this is quite common in them, the consequences of an unsuccessful exit of a soft beetle from the pupa. But Pimelia seems fine, so what's so ugly about her?

Blaps transversalis Ball. and Pterocoma. The latter is similar to ganglbaueri, but I'm not entirely sure.

Thank you for the correction, dear Milabris, it turns out that this is a sign of the species. I hadn't thought of that. I saw a lot of wrinkled halophila and lethiphera And with pterocoma I punctured

Well, yes, I'm sure you know Wed. Asia better here

16.04.2008 18:38, Mylabris

And blyaps really are all sorts of wrinkled-as it seems to me, they just came out of the pupa and "got stronger" in not very comfortable conditions. Or when such a fresh one is washed and pricked - it also happens that the elytra change somewhat.

Very interesting. Unfortunately, I didn't know anything about it. And where do they come from?

Over 1.30 Yes, lots of streamlined seats. By the way, I measured the index of the pronotum width of the patronbus image. It turned out to be equal to 1.18-1.19 So what is it after that?

I'll check the labels next Wednesday, if I can get out. As for mine, you can easily guess

Over 1.30

You are absolutely right, it says over 1.30, I overlooked it.

Similar bug with caught Rippers (Subject "Fishing Report")
Lviv, Kaiserwald Park at the source of the stream under the stone.
8 mm
Presumably some kind of bembidion Sinechostictus ?

Thank you, I told you it should be easy. I thought that the specific feature for this species was wrinkles (they were all there, and fast, and strong like...).
Yes, this is the same Medvedev, who seems to be engaged in the world fauna of black-bodied animals. I still have a lot of uncertain things left from the black chicks of Central Asia and Kazakhstan (although most of them were determined by different specialists) - but time and slow Internet... Maybe I'll send you more later.

I ask for help in determining Aphodius before the species. The main hope, of course, is for Mr. Nimrod

The beetle was caught on the sandy shore of the reservoir in the vicinity of Kurchatov (Kursk region), under a stone, 18.04.2008

For me, so from the subgenus Chilothorax. Maybe a female transvolgensis?

Is it his platelet that's so granular??? How does A. (Ch.) ivanovi Lebedev fail? A biotope, basically its own, but the species was considered endemic to the Volga region, as far as I remember. Although it is colored differently... So there might be something very interesting.

Yes, those were indeed Sinechostictus, most likely... This one is also similar, in general. And how does it pass through the keys?

19.04.2008 0:10, Necrocephalus

I don't think it's transvolgensis. Firstly, the coloration is quite different, and secondly, it occurs much to the south-east, as far as I know...
A. ivanovi is also unlikely, despite the sculpture of the platypus. I thought of this view first, but it didn't. And the color is not the same, and the shape of the pronotum is different, and it is too large (almost 5 mm).
As for the subgenus, it really looks like Chilothorax...

Thank you, Mr. Necrocephalus, for your confidence. Of course, I will try to twist this female, but I had some questions along the way:
- is the shield normal or narrow?
- how long and thick are the bristles on the edges of the pronotum and near the shoulder corners of the elytra?

It really does resemble something from the subgenus Chilothorax (thank you, gentlemen), but if it is a melanist, and even a female.... I will try.

In general, as far as I understand, females of other species of this subgenus also have similar things with the platypus...

19.04.2008 1:03, Necrocephalus

- is the shield normal or narrow?
- how long and thick are the bristles on the edges of the pronotum and near the shoulder corners of the elytra?

In my opinion, the shield is normal, not narrow. The density of the bristles in the place you indicated is moderate, they are quite long. For clarity, I post two photos, on one of them the same bristles are more or less visible, on the other - the shield.

I don't have any keys to them.
Judging by the Polish list of them (Sinechostictus), there are 5 species in our region.

I myself do not know this subgenus, so maybe you are right, but out of curiosity I looked and found that of the species listed in Wrighter (5) and Pawlowski (Poland, 4 species), the largest is max.7 mm, and it has a metallic luster on the nadkr. The rest is less than 6 mm.
According to Kryzhanovsky (1983), in the species of this subgenus, " the 8th furrow is tilted. in the anterior half it is shortened, often flowing into the lateral edge in the apical third or in front of it. Prothorax in rough spots, Prsp, narrow heart-shaped, very narrowly bordered."

That's right, Myka. And the line-shield bug (Italian bug) - Graphosoma lineatum L.

Mike is a male Meloe violaceus. If possible, specify the collection location and importer.

I think I will not be mistaken if I say that the T-shirt is Meloe violaceus

19.04.2008 20:28, guest: omar

Well, the specialist beat me to it. "I'll fall, I'll cry in the sheets "(C)

19.04.2008 20:51, RippeR

These beetles are already almost in full swing - that is, enough but not yet supermajor.
Milabris: Place of capture Moldova, Transdniestria. Memes will be more precise. And why the data on violaceus?

19.04.2008 21:03, Mylabris

I have been compiling a database of points for 7 years now, not only in Kazakhstan.

The bug was villainously caught on a nettle leaf in its own thicket, 6 meters from the reservoir, 19.04.08. Kitskansky forest, Transnistria

20.04.2008 12:21, metallman.92

To metallman.92: Agriotes obscurus (L.)

Great! So confidently and immediately Agriotes obscurus. Why not Agriotes sputator?

How was "in years" determined? Please explain!

20.04.2008 21:22, metallman.92

oh.... my picture didn't load...here I go..and .. bam and she's already here))) what is this bug?? 8 mm. in length (without antennae), when you turn it over on the back, it somehow jumps 3-5 cm up to turn over)

The two posts preceding yours answered your question. This is a click beetle (family Elateridae). The genus is definitely Agriotes, but the species is not clear to me personally: Buzman is definitely for A. obscurus, and it seems to me that it is quite difficult to distinguish it from A. sputator from the photo...

To Dmitrich: Pronotum markedly transverse. At sputator, it is still more elongated. But with basins, of course, it would be more accurate, I completely agree with you.

Left - A. obscurus, right-A. sputator

Isn't it Paranchus albipes ? Here at Buzman-and looked in the reports.
Beautiful reports ,and most importantly, everything is detailed.
