M. brunnipes with hairs, and my nutcracker without them. And I print out books right now at work, since there is an opportunity!

To Buzman: I sat down to write at least to the end with comparative material on the whole of Central Asia and realized that each photo needs additional angles. If you do not mind, it would be great to see each of the beetles: total bottom, total side, side hind legs, front legs. This is the minimum. Questions may appear later - this is a very difficult diagnostic group.
And more. I would like to know more about the localities... (for example, V. Kazakhstan - where is it?), although I suspect that you don't know more exact localities - you would probably write them.

Good evening. Help with the gravediggers.
1. sort of like Nicrocephalus investigation investigation
But there's a red spot on his forehead...or is it not on the forehead such a spot?? and so it fits all the signs.
picture: P9100122_.jpg
picture: P9100121_.jpg
2. also suitable for all signs, but the main color is not black , but brown..
picture: P9110127_.jpg
3. also very similar, but on the pygidia the hairs are not yellowish, but as on all segments of the abdomen they are black. And there is a black spot on the shoulder epipleures. Also on the sides of the middle breast, the hairs are not so long and thick, rather short. there is a suggestion by N. sepultor/. Tell me

And the "spot" is not on the forehead, and not a spot. This is a membranous insert of the platypus. By the way, its form is used in diagnostics umnik.gif
About sepultor-question... As far as I remember, it's not Asian. You can also have your own views. By the way, the network had keys for this genus in the volume of world fauna.

Yes.

So far, there is not a single determinant for Kazakhstan (which I am working on). Determined by green + Mongolian + Turkmen. There are also 2 reports of Skopin on the South and South Kazakhstan-then there are only lists without tables.

Thank you, but don't tell me a link to these keys, if possible. smile.gif

Nikolaev I have, I also downloaded it somehow, but I don't see long yellow hairs on the back of the chest and epimers in this instance.I just clarified this, but at least the sign is relative..I may be mistaken

25.03.2009 17:58, Cerambyx

Yes, it's a muddy story. In general, it seems to be either argutor or mongolicus. Let's see what V. O. Kozminykh has to saysmile.gif

Good evening. There's still some material from the north. Northern taiga, on the parallel with Igarka, Krasnoyasrky Krai. Caught near the water.

Thanks!!

25.03.2009 18:45, Fornax13

2 - Asaphidion, of course. Whatever... Not pallipes by accident?
3, 4 - Pelophila borealis probably.
5-Yes, from this pile - Agonum (Europhilus) of some kind.
The staff is cute, from Omaliinae, but it is necessary to look at it.

Oh, this is such a staff..Well, then I'll put it aside, these animals are generally alien to me smile.gif
Pelophila, I didn't hear anything like that...and what is typical for them?? I'll check it out tomorrow..
Well, on agonum I still go to this view, maybe there will be more experts, so they will correct it smile.gif
For asafidion, I really have no qualifiers, as well as for his "colleague" bembidion, as everything is so complicated there smile.gif
Thanks!!

25.03.2009 19:06, Fornax13

You're welcome! smile.gif
Take care of your staff - it will come in handy smile.gifand omaliins are not the most difficult group to define.
Pelophila borealis - almost a holarct. A genus close to nebryas. And in green, and in DV there is.

25.03.2009 19:41, akulich-sibiria

by the way, thoughts about the fact that something similar to nebriyami I ran somewhere deep, somewhere very deep)))..I'll find out the truth tomorrow. wait with new photos if anything!!)))

28.03.2009 8:44, akulich-sibiria

Good afternoon. not a very good photo, but maybe tell me. It seems that everything is simple
1.Geotrupes stercorarius. on the hind legs there are 3 solid transverse ridges. On the abdomen, the hairs are evenly spaced.
picture: P9130152_.jpg
picture: P9130150_.jpg
2. G. stercorosus 2 whole combs. The grooves on the elytra are weak. The first prong on the front legs is not forked.
picture: P9130155_.jpg
picture: P9130159_.jpg
3. I can't go to work. Khakassia. 6.5 mm.
picture: P9150166_.jpg
4. something like from the Melandryidae
picture: P9150174_.jpg
picture: P9150175_.jpg

As for the past ground beetles, Alexey, you were right!! this is exactly Pelophila borealis, and for agonum I decided on A. (Europhlus) fuliginisum

28.03.2009 15:07, akulich-sibiria

Help with leaf beetles.
1. Chrysolina gramminis gramminis The
rollers are poorly developed. It is difficult to understand whether there are stripes on the elytra or not..It can be seen that the suture is darker and on the disc of the elytra. (then maybe Ch. gramminis auraria)
picture: P9150179_.jpg
picture: P9150180_.jpg
2.Ch. gramminis artimisice. Coarser and more wrinkled punctuation on the elytra. The ridges on the pronotum are less pronounced.
picture: P9150181_.jpg

28.03.2009 15:23, Fornax13

1-I think - this is what was called Geotrupes baicalicus. I don't know what the status is right now.
3 - Bembidion (?Asioperyphus)
4-I would also say that Xylita laevigata.

1 - and the first one is generally graminis? rolleyes.gif

confused.gif Here is a question on 1 bug...I don't even know if I looked at Zina's website...I'd like the keys to them. There is also baicalicus...now it's hard to say.I will search for information on them. do we have G. stercorarius in Siberia??
by leaf eater..Well, I have no other options. If only Chrysolina cerealis.but this one generally has bright stripes..
on the site of Zina gramminis with some really bright stripes on the disk. I used Medvedev to identify Siberian leaf beetles. but there are no pictures there.

28.03.2009 17:15, Fornax13

Well, we have baicalicus, but G. stercorarius doesn't seem to live anymore.
Ahh, well then maybe... But the sculpture is too thin for graminis.

1 - Bolitobius or Ischnosoma. It seems so now.
2-Oxyporus like maxillosus
3-Oxyporus is also some kind
of 4-pronotum and head can be larger. It looks pretty, maybe even Quedius is like that.
5-Ontholestes
6-Anotylus
7-Possibly Lordithon, but not rolleyes.gifreally
