Not, not like, either picta or lineata.( They're over there:

The big one is really C. picta, and the second one is not lineata in any way.

Are these males of Psilotarsus brachypterus? One such monster (about 3 cm) was rolled up alive by a spider. Aktolagay Plateau, June 27, 2009

Still, Ustyurt beetles are well defined, not like other orders, even butterflies... Thank you friends! Nutcrackers mostly remained, but heterocerids...

I would say yes, here is another subspecies to clarify-as a variant of ssp. aralensis Danilevsky, 2000 - in more detail in the revision of the genus (I unfortunately do not have)

Staff - Physetops tataricus, like now all reduced to one species.
What's wrong with heterocerids? Small Augyles?

PS IMHO such a spider will roll up anyone - it's very similar to karakurt

Here are two more difficult May days from the south of Ustyurt:

I can only offer to choose from two - Omophlus pilicollis Men. and O. deserticola Kirsch. True, it doesn't look like the first one, but I have no idea what the second one looks like. There doesn't seem to be anything else of the family living there, but I might be wrong.

I found the pollen eater detector online (?Russian Federation), the key that led to pilicollis (hairy elytra). But mine are bigger, with longer whiskers. Probably some other, local, Turanian type.

Quite likely! As for the fauna, I was based on fairly ancient information, which is why I'm not sure. Give a link to the key of pollen eaters, so as not to search

for it yourself

Apparently also some kind of pollen eater?(I only found it once). From here:
30.06.2001 M. O. Balashikha district okr. der. Poltevo (9-12km. from MKAD approx.), length 12 mm. Please help me figure it out.

good evening. Krasnoyarsk Territory.
1. picture: P4170139_.jpg

4.I can't figure out what the nutcracker is. It has spots on its elytra formed by golden hairs.
picture: P4180159_.jpg

5. something from RAbocerus, no more than 3 mm. Black, shiny.Pronotum and head are roughly punctured. Antennae with 3 strongly enlarged last segments, then the segments are reduced. Upper lip is transverse. Previously caught R. gebriel, it is possible that it is R. mutilatus ?

1-Bembidion most likely quadrimaculatum
2-Omalium sp.
3-Tachyta nana
4 - I would wash

it It is likely that it will be covered in golden hairs.
5 - and on the DV where does it go?

Ouch! Well, do not prick your left elytra, and even more so on rusting stationery pins. It is better to glue on the dies.

often the beetles are not mine or it's from the distant past, when I was a child, killed insects with a sneaker or in the sun. )))..don't judge me harshly. But the fact that they often get dusty is a problem for me. Because you work with the collection constantly

YES, in the yard there is only foveolatus, tomorrow at work I will look at the signs. Th the not thought, there look. But still, something in the signs is not quite it.
And according to the nutcracker, he has a well-defined semi-adjacent pubescence of white hairs in addition to these spots. At least go to the homeland.

I didn't find anything at Cherepanov's

1. Bembidion quadrimaculatum (similar-B. mandli, it doesn't reach you, including no variants).
3. Dirty Tachyta nana (barely realized)

I thought for a long time - I was late

and who else can I contact for help in identifying snappers? I have a lot of them here, and there are also a lot of questions about them

28.10.2009 17:23, akulich-sibiria

And also for Rabocerus, it was confused that it was found on timber (spruce), although for the described species it is indicated that they are related to hardwoods

28.10.2009 17:31, akulich-sibiria

in the green identifier, there is the species Lado jelskii, so at least I identified a beetle caught under the bark of a fir tree in the paths of Polygraphus proximus. What is the name of this genus today? Unfortunately, I forgot the photo at work. the beetle is brown in color. 3 mm. Flat, long. the lateral edge of the platypus covers the 1st segment of the antennae. Elytra with ribs spaced one at a time. They have poorly visible pressed hairs. Pronotum with bumps, but not clearly longitudinal. Antennae with a 3-jointed club. Eyes in front without a notch.

28.10.2009 17:56, akulich-sibiria

1. a beetle from the grinders (I believe). 5 mm. I am inclined to the genus Ptilinus.(female.)
The antennae are deep-sawn.(last 6 segments)
The edges of the pronotum are sharp.
Elytra in tangled uniform points, do not form rows and ribs. Pronotum slightly transverse. In the middle of the pronotum is a weakly marked longitudinal groove.
picture: P4170152_.jpg

2. among the numerous Triplax aenea, there was found a beetle similar in appearance, but slightly larger and its elytra without a blue gloss, black. Its trim is brown, not red. It seems to me that this is T. scutellaris. Tell me if it's him.
picture: Triplax_scutellaris.jpg

3. Is this Gastrophisa polygoni ??
