Can I detect a couple of beetles?

01_IK picture: IMG_01_IK.jpg

02_IK picture: IMG_02_IK.jpg

Among a dozen specimens of O. taurus, (photo 03_IK),
there was one "not so" - presumably O. illyricus (photo 04_IK).
Can I use this photo to confirm the name of the species?
And is it normal for taurus to have short horns-photo 05_IK?

of Prosternon 02_IK - perhaps Athous is

For Fornax13
, Thank you for your continued help.
Do we agree on 04_IK - c illyricus, or do we have any doubts?
It was suggested to me that the differences in the band along
the junction of the elytra. It didn't look good in the photo.
Maybe you need to look at other keys?

It is necessary to look at the hairs on the elytra. In taurus, they are only on the sides, in illyricus and on the inner aisles (alas, they are easily erased). In illyricus, the points on the elytra are small rasp-shaped, in taurus small simple ones. illyricus is slightly more matte on its own, with a clear metallic sheen and with lighter ndkrs.
Unfortunately, I can't say for sure, because there is nothing to compare it with: I only have illyricus... rolleyes.gif

30.03.2009 0:31, Fornax13

1, 2-can P. niger be used at all? O_o
3, 4 - Harpalus (subg. Pseudoophonus) rufipes as if
5-Cymindis some kind of cute. I think C. picta
6 - Chlaenius spoliatus
7-Lebia cyanocephala
8-Panagaeus bipustulatus rather
9-like again H. rufipes
10-maybe and H. griseus...

For Fornax
, the remaining hairs were viewed with binoculars.(!)
I hope this season I will pick up more such copies.
I can share the tauras.

30.03.2009 0:37, Fornax13

Thanks! Yes, we have it much more common than Illyricus in theory. Just no luck on it. But illyricus was collected everywhere: in a woodchuck hole, in the forest, even on rotten fish on the shore. At one point, true, but still.

Please tell me about the Carabidae. Found under the bark of a cut stump, Kiev, park. It seems to me that someone from Harpalini?! I'll try to assume that Harpalus???? For me, this is a dark forest!!! Thank you very much!!! About 12 mm.

I don't know much about beetles, but I'd like to ask you a stupid question. And exactly Prosternon?
And not Agriotes of some kind?

exactly Prosternon?

To Mylabris: Sergey, I made the right angles, but so far only two animals. But che-ta forgot about the hind legs on the side (instead of them, for some reason, he removed the hind legs)… smile.gif Then I'll add my paws if necessary. The rest of the animals will also be photographed over time, but the quality of the photos, of course, makes much to be desired… Thank you very much in advance for your help!

Good evening. I have a few questions here.
1. I would like to return to Geotrupes. I dealt with my own people.I posted the photo above. According to Nikolayev, I can't fully understand the definition of the species by the front legs of males. Can you tell me how to distinguish a male from a female??
I post photos of the front legs of two beetles that were previously identified as Geotrupes stercorarius, but I tend to warm to G. baicalicus in their area.

2. is it possible to determine staphylinid before the genus??
picture: P9190014_.jpg

3. Say it's Synchrmonia conglobata? Color slightly podkchal, it is pinkish in color.

01.04.2009 19:30, Mylabris

To akulich-sibiria: IMHO, the sex of geotrups (like the vast majority of scarabaeids) is easier to determine by the shape of the pygidium - in males it "crawls" more strongly on the ventral part. A staphylin from the genus Stenus.

02.04.2009 1:28, Fornax13

Stenus from sensu stricto. It resembles S. bimaculatus, but you should still look at it.
BC I would also call Oenopia conglobata.

I think the specialists will tell you exactly later, I can only assume.
1. Harpalus sp.
2. can Pterostichus niger
3. Serica brunea
5. Aphodius some maybe something from Chilotorax

04.04.2009 10:38, Mylabris

Harpalus distinguendus I think.
And a swimmer like Dytiscus, a subgenus of Macrodytes, you look at the" green", there are key signs at the bottom to look at. Its sides are yellow or does it shine like that?
