Maybe obchestvennost enlighten, plz. What is the difference between M. exaratus and M. septemcarinatus? The structure of the elytra is the only thing I could get out of comparing different photos.

Calves, calves, here are more detailed pictures of the Ural "yeharatus" -

This also seems to me to be the most striking difference.

Septemcarinatus is larger than exaratus, slimmer, the main background is with a metallic blue-bluish tint, the pronotum is more elongated, its sculpture is more crudely wrinkled-dotted, depressions along the edges at the base are deeper. The structure of the elytra in both cases is heterodynamic, but exaratus has clearly defined continuous secondary spaces, while septemcarinatus has flattened secondary spaces and presents fine granular lines. These are the main external differences. About more complex differences (the number of setae on the posterior basins, pronotum, the structure of the submentum)
I can't say anything. The lamella of the aedeagus in exaratus is thinner and more curved. smile.gif

To the question of the Ural exaratus, see if it is the same and if there are any obvious differences

Cara2-Carabus (Megodontus) exaratus Quensel, 1806-definitely! Color form with green borders. Typical - with purple ones. There are dark specimens with a barely noticeable purple (blue) border of the elytra and a faint bluish tint of the pronotum (melanistic form?). Another interesting question is that there are no subspecies listed in the entire range, although this is rather strange, since there are really isolated populations, as Cerambyx accurately noted!? confused.gif


In fact, there is a name for these populations, and I even saw some beetles signed here, but unfortunately I didn't remember them. You need to look in synonyms.

Most likely-Carabus granulatus, and it looks like a female...

06.03.2007 12:14, omar

Exactly granulatus!

06.03.2007 12:32, -Дзанат-

Thank you all! According to V. G. Shilenkov, this is how I got Carabus granulatus ssp. duarius Fisch., 1844 (=ussuriensis Born, 1914)

Hm.. does Carabus granulatus have a variation with red thighs? I pulled something similar out of the trap today)

Rather, C. cancellatus

Mm... it is possible that the traffic on the images has ended here and on the pdf-ki, I will come home tomorrow to clarify)

A few posts above have a scan. In the nominative subspecies, I have not seen aberrations with red thighs, but I admit that it is possible.

More than half of us with C granulatus have red thighs.
My subjective observations are that the wetter the biotope ,the more people with red thighs come across .

Here on this ground beetle there was a question -
user posted image.

At first I decided that it was Carabus karpinsky, but something is not very similar in biology and is completely massive, including on the plain.

16.06.2007 14:13, Furslen

2 more angles of the same carbuses - user posted image

Additional photos and a species sketch in the CC of the Chelyabinsk region of the species that we suspect - Ground beetle of Karpinsky( Carabus karpinskii).
Actually, the abundance of these beetles is confusing, although it is close to the described range, but on the plain, under snags, stumps, etc.

Is this species familiar to anyone?

It looks like it is - Karpinski's karabus. In my opinion, there are no other representatives of the Morphocarabus subgenus in the Southern Urals. And the size of the beetle? By the way, you mentioned an interesting fact. If you have observed ground beetles before this season, and this year you are surprised by frequent finds, there may be an increase in the number due to favorable conditions. This happens periodically.

Sorry for the quality - here is a picture of my M. karpinsky. I haven't heard about the finds on the plain, but they say that on Iremel it is one of the most common beetles.

Help identify a karabusa, Moscow June 22, 2007
Hefty size, 4 cm. Sorry for the quality, I didn't fit under the binoculars. I had to click the soap box directly.

this is the Carabus coriaceus, aka "procrustes".
cool bug

25.06.2007 21:16, Nilson

Definitely, the shagreen ground beetle (Procrustes coriaceus) is a red book species in some places. Like, male.

26.06.2007 8:03, omar

Where did you catch fish in Moscow? It is not available everywhere. I won't catch it myself, just curious for the point.

Omg.. is there a procrustom service in Moscow? 0_o has long wanted to catch a couple of live ones to watch.... and where do they come across?

Thanks for the definition, procrustes (1 copy) caught in banks in Krylatskoye.

And somewhere in the background.
Just at the edge of its range, like every species, it is rare and sporadic.
For example, I caught a Carabus (Trachycarabus) estreicheri in our region this season . Somewhere banal, and we have in the post-war years the first capture.

Procrustes coriaceus in the Moscow region is not so exclusive. In some places, it is even mass-produced. But there is not everywhere.

I agree that C. coriaceus is not rare, but it is local. Forest mesophile, in broad-leaved and mixed forests. It is quite resistant to anthropogenic pressure and disappears only in heavily disturbed forests. In the Tula region in the forest zone is quite common.

For Entalex: is there a way to specify the location of catching your carabus? Here is a verbatim preliminary answer by Dmitry Obydov: "It resembles C. prometheus miroshnikovi in its features. We need a more precise
locale (preferably with an indication of the locality), because
Zamotailov described several other poorly distinguishable taxa from this region. "

Omag, thank you for your cooperation! Carabus caught in the afternoon at the footpath, alpine meadow. Lagonaki plateau, approximately 5 km southwest of the campsite "Lagonaki" (Azishsky pass), or-about 5 km northeast of Mount Oshten, or 12 km west of the village.Guzeripl. Posting photos of the area of capture.

The photo shows C. prometheus prometheus m. nubicola Zolotarev, 1913.
You can only determine the view from a photo if you know the exact locale.

Omar, my gratitude knows no bounds! mol.gif
So KDG was right! He also has a lot of respect for the tip and information. beer.gif
Thanks also to D. Obydov for his help in identifying the problem. jump.gif
No matter how much I get confused, I still have a ma-a-scarlet worm swarming around inside - we need to look for where you can watch a live series of C. miroschnikovi.

The Karabus is large. Body length 35 mm. The photo was in a different topic - I'm correcting myself and putting it in its proper place. wink.gif
