Damn, that's right, what a fool wall.gif

Indeed, I pulled out the front shin, it is triangular, one in one, like in No. 2.
So No. 2 and No. 3 are Margarinotus brunneus, as the dear Omar said.

So to summarize

1. Hister unicolor Linnaeus, 1758 (not painted)
2. Margarinotus brunneus Fabricius 1775 Unicolored
carapace 3. Margarinotus brunneus Fabricius 1775 (=impressus (Fabricius, 1798) =cadaverinus (Hoffmann, 1803)) Carrion carapace

Thank you all
and a beer beer.gif

And why does the spot bother you? It's common for this kind of thing to happen. Alternatively, Smaragdina affinis. Take a look here:

And where is your beetle collected? confused.gif In Siberia, Cheilotoma musciformis seems to be absent...

In deep pardon redface.gif! Now I looked at Benkovsky A. O., and I was convinced that this beetle is indicated for Siberia! If this is Cheilotoma musciformis, then, of course, only the female (the male Cheilotoma has a huge head!). You need to look for oblique depressions that separate the posterior corners of the pronotum from the disc. I couldn't see it in the picture...

Help identify staphylin. Quite small, just over 2 mm. On clearings, pine forest.

this species is listed in Medvedev for Siberia, that's for sure. I'll take a look at the rear corners one of these days. When I defined it, there were no questions. and it really looks like Smaragdina affinis, although this particular species is not preiveden in Medvedev. I briefly looked at other types of smaragdins, but I didn't find anything similar in the description. Are you sure affinis lives here?"

I'm afraid to make a mistake, but in my opinion, something from Aleocharinae

29.03.2010 13:06, Sugercete

I have reached the point of leaf eaters.
It seems to be similar to the akulich-sibiria beetle, so I decided to start with it.
I ask for help in determining.

Hmm, I've never even heard of it.
Something valuable?


It is found all over Ukraine, but everywhere it is sporadic and rare, which is associated with ecology. The species develops in the wood of the shrub Staphylea pinnata (there is a photo on the Internet), it is obvious that the beetle also covers other plants of this genus, and possibly some species from the adjacent maple family.
Imago is found on flowering oaks and horse chestnuts.
I got 1 copy. to kronovaya on the oak tree. I sent a photo to M. L. Danilevsky, who said that my copy was A. gracilis.

Yes, from the Aleocharinae, of course... But then...))
In principle, it resembles something from the small species of Aleochara (or something very close to them). Unfortunately, I haven't dealt with them yet.

about Cheilotoma musciformis . here are more photos. I tried to take a picture of the angle where you can see that the rear corners are bent up, just written that this is typical for this species.

2. Something from the Throscidae. The beetle was found in the rotten wood of Siberian pine. The beetle is very destroyed. In the Far East, the genus Aulonothroscus was found
with antennae with a three-jointed loose club. 4.5 mm.

Judging by the habit, it is indeed Aulonothroscus. Is it really 4.5 mm? O_O Does it have a belly in place?

the belly is lost somewhere, I wanted to cook ediagus, ... in short, I lost it..what was there to see? Beetles seem to have lain all winter in the wood and when heated in water, the beetle just began to disintegrate
I think in a week I will go to inspect the forest again, then I noticed the log. I'll try some more digging.

Well, for the sake of Edeagus, actually... ) Or you can also see if the bag is female. In it, the sclerites seem to be species-specific in shape.
In general, I do not know a troscide of this size-usually smaller than 3.5, only some aulonotroscuses are slightly larger.

We have spring already on the threshold, the willow has bloomed, I think the first apids will soon fly. Andrena, too. I think I'll catch more of them now, and send them to you for identification. By the way, can you tell me what is better to put in the stains? They say ethyl acetate is good..where can I buy it?


Wow! The willow is already blooming! We still have winter. frown.gif
I use ethyl acetate in stains, but I used to get quite acceptable results with chloroform. The main thing is to prevent bees from coming into contact with the liquid. If the pubescence gets wet, then the hairs stick together and the appearance of the specimens is not very good later.
Damn, something off-top turned out...

30.03.2010 18:55, akulich-sibiria

I think it is incredibly difficult to identify these guys from the photo, but still someone can tell me.
Apion. just under 3 mm. It was caught in the Krasnoyarsk Region, in a pine forest with an admixture of birch. The cephalothorax is rather long, slightly curved. The scutellum is longer than it is wide, but there are no visible bumps at its base. The grooves are clear, the gaps are raised. The main antennae are dark brown and shiny. The body is slightly pubescent, the entire beetle is black, without an obvious metallic sheen. The eyes are almost round. Shoulders are well developed. On 2-4 segments of the legs pads of light hairs.
As options-minimum, radiolus....

well, this friend is definitely more than 4 mm. Tomorrow I'm going to the forest, poking around in this log. Although I think the beetles there are not in the best condition budut

This is just simple - Betulapion simile (Kirby). On birches, the most common view.

And our spring was again replaced, I hope, by a temporary slush. But I think I'll start hunting in mid-April!

I humbly apologize for the slip of the tongue - "subspecies"-in fact, I meant aberrations.
Actually, the question was born from looking at the drawing ("Fig. 869-905") in the topic of the Saratov region. I somehow imagined that there is no" absolute "similarity (although I am aware that there should not be an" absolute " one).
Once again, thank you!

31.03.2010 18:37, akulich-sibiria

Unfortunately, I haven't found any beetles of the genus Aulonothroscus yet. But I also found two other beetles.
The first, I believe, is of the Eremotes family. Several live beetles were found in the rotten cedar wood. The top of the elytra is covered with small single hairs. The antennal grooves are steeply curved under the eye. Vertex slope without grainy sculpture, intersections with a number of points. Pronotum in large spots, slightly longitudinal.
Alternatively, E. porcatus was identified by green.

2. Grinder beetle from the genus Xestobium. The last three segments of the antennae are enlarged, but not larger than the others combined. Ver of the body in the adjacent hairs forming spots. The body is dark brown in color. Pronotum slightly wider than elytra. The ediagus is similar to X. elegans, and this species is also listed on cedar, but it is disconcerting that it is a species from the Far East. It is similar in habit to X. rufovillosum, although it is indicated for deciduous trees and sometimes on larch. Please help me identify these beetles!
