Why dubia and not sanguinolenta?
As far as I remember, they are distinguished by bumps under the eyes.
I would be very grateful if you describe exactly these differences.

the size of the temples differs dubia from reyi (in the latter they are smoothed).
a more hairy pronotum differs from sanguinolenta, the nature of the pubescence of the elytra is also different, and dubia is more variable in color (clearly seen in the series).

Ripper also wants to give files with photos unique names (best of all, leave the ones assigned by the camera).

02.03.2007 22:01, RippeR

I'll take everything into account. Just the first time with such a volume of photos faced, I didn't even know about all these trulnosty

Everyone has the first time and usually most of it is like this..

02.03.2007 22:15, RippeR

KDG:
the leptures seem to have a different sculpture, and pay attention to the pronotum and head, they are also different, so it's interesting to be more precise. And I also defined the male as a dubia.

ground beetles
1. Ukraine, at night on the beach.
2. Moldova, Vadul-lui-Isaak, ran on the ground (as you can see

from it )

All Carabidae are Acinopus spp. You will get to the view on 2 volumes.

also from the same family? It turned out interesting.

03.03.2007 18:39, stierlyz

And, I remembered, a large one - A. ammophilus, it is sometimes confused with Zabrus, it used to come across quite rarely, but now we have become b. m. ordinary.

I also identified a large one, but I can't find a small

one, either laevigatus or picipes.. It's a pity there's no microscope. And there are also such signs - thin or clear grooves, some kind of clipping (the picture is also poorly understood). Maybe someone with both met, knows?
I'm leaning towards picipes, as it is specified for the Odessa region, where I caught it.

bidnes or the idiot? The horn is one, but it seems to be forked towards the end, I don't even know where to put it. Quite large, 23 mm.

You are making progress, Mr. RippeR-signs of a certain "systematization", and, therefore, progress-are evident....

Both small Acinopus leicht zu verschieden by cutting on the mandible, with optics, naturally. And both of them are unas (and in Moldova) common.

Thank you very much, styerliz, for your valuable information. It will be very interesting to learn from the" local " specialist, which species are found "there" more often, which are less common. I would be very grateful for such information!

04.03.2007 16:30, RippeR

ab. ottomanus Reitt..
What does this mean, and what other aberrations are there?

"you've got that female a little strangled. "I don't
understand much about these kuzmas, anisoplyas and others, for me they are all so similar - and who knows exactly where.. I can't understand their taxonomy.

"Acinopus leicht zu verschieden"
How do I understand this?

04.03.2007 22:22, okoem

What is the name of the beetles?
The ground beetle is approximately 15 mm long.
Manure is about 10 mm.
Crimea, Feodosia, March 4, 2007.

20070304_141015.jpg -Aphodius (s. str.) conjugatus (Panz.) - not a bad species. It is quite possible that the subgenus is already different, but now I can't predict more definitely - there are no recent revisions for them at hand.....

Well, there are still all sorts of things.. so far, I haven't figured out all of them (or rather, none of them)

, the same hoplii and others..

Hoplia-they're from a different subfamily, sort of...

05.03.2007 1:50, RippeR

It's understandable.. but these closely related subfamilies are Kuzka-like.. in general, I get lost when trying to understand their classification.

05.03.2007 2:39, omar

Ground beetle Zabrus spinipes (blapoides), most likely. Although it is most often larger than 15 mm. If this is it, then in Crimea it is a background view.

Thanks! I think you're totally right! I have met such ground beetles before. And I really made a mistake with the size... It is slightly larger, perhaps closer to 20mm.

05.03.2007 9:51, omar

Just about in the region of 20 mm. It was the size that confused me the most.

Mr. okoem, if you have the opportunity to visit the Sevastopol region (Inkerman) during these weeks (namely, where H. subseriatus flies) - look for it, okay? You may be lucky with larvae and pupae of this species.

Actually, this is probably better in the topic of "Crimean beauties"... I can probably get to Sevastopol in two or three weeks.

Help me identify a very beautiful ground beetle. The photo is not very good.
Moscow region
Do I get either Platysma? either Agonum?

Dzanat, the beetle is similar to Pterostichus (which, like, used to be Platysma, if I'm not confused).

If you need keys from the" second volume " on Carabidae-I'll tell you where they are.

06.03.2007 12:01, Dmitry Vlasov

Definitely Pterostichus sp.
If its length is about 15-17 mm, look from below at the claw segment of the hind or middle legs. If it has not only a pair of setae at the claws, but also a few in the middle - this is P. melanarius. If the length is 10-13 mm, there are several types here and there...

06.03.2007 12:25, -Дзанат-

Length 17mm, a pair of setae on the claw segment, only on top.
vilgeforce Vladimir, what is this "second volume"?

06.03.2007 12:31, Dmitry Vlasov

Determinant of Insects of the European part of the USSR (what is sometimes called the "green" Determinant), volume 2 Coleoptera, 1965

06.03.2007 12:36, -Дзанат-

That's just what I don't have, there is another "green" old 1948, but just as thick

Thanks everyone. If it is the bottom without bristles, then Pterostichus niger Schall is most likely it is

Dzanat, here is the beginning of the second volume: http://scibooks.narod.ru/biopdf/randet2.pdf
The carabidae are complete there.

Schall is not very similar to Pterostichus niger, this one is more flattened and the pronotum is somewhat different. And where is the beetle from?

06.03.2007 15:42, -Дзанат-

Yes, well, I don't know then, according to the determinant "green" it turns out either niger or melanarius
Here is a niger from the site koleopterologie
http://www.koleopterologie.de/gallery/FHL0...oto-gebert.html
Near Moscow, in a soil trap, he finished his journey.

06.03.2007 16:05, Guest

I looked again, just R. niger process pgr. not edged, an. stern. male with a longitudinal keel.

06.03.2007 16:07, -Дзанат-

Eh.

06.03.2007 19:39, omar

I really want to help. But in this case it is impossible-the beetle must be turned from all sides....

For RippeR: MD.17.07.04.jpg — (142.11 k) from 01.03.07 13: 28-Agabus undulatus (Schrank). MD.26.06.04.jpg — (145.45 k) in the same series of images-similar to Dirrhagus (from Eucnemidae).
MD8.jpg — (146.96 k) and MD9.jpg — (151.7 k) from 01.03.2007 11:58 - the genus Leistus, the first is similar to L. piceus Froel., the second-to L. ferrugineus L., but possibly rufescens F. (in the photo, the posterior corners of the pronotum are poorly visible).

Not niger exactly. There, a whole complex of species has anal sternitis with a groove. And besides, the niger is one of the largest pterostiches, and the pronotum is a different shape.

08.03.2007 9:20, amara

Zanat, this is Pterostichus niger from my collection. By the way, also from Moscow and also approx.17mm. Quite similar.
Happy holidays!

returning to the topic of Agapanthia, I wanted to know what it is? villosoviridescens was discarded ,as this species is smaller(10-14 mm) and with a solid gray color.
Lviv region. Pustomytovsky district of the village of Dublyany.
