Dear colleagues!
I must admit that looking into the forum a week later, I was
very surprised by the degree of heated passions, which
generally boiled down to two beetles - one of the kind of T - shirts, and
the other-chernotelka.
Due to disagreements, we moved a little further away from the topic
- and began to find out the competence of individual forum members in
identifying representatives of certain groups.
Since the requests for clarification
of the species belonging to the T-shirt were given above, and there is still a debate
about the black heifer, I want to write a couple of lines.
First. Mikey is not a strange band to me, I have been working with them
for 7 years. The proscarabaeus-violaceus pair is not
always easily distinguishable. I think that each of us
has met with such specimens when you do not know
what kind of species they are at first glance and which
can be determined reliably if you have
a large series of species "on hand". T-shirts of these two types are most easily
distinguished by their sculpture and color - proscarabeuses

colour. In addition to such "walking" signs, there are

differences in the structure of male genitals and antennae, as well as

in the sculpture of the prothorax (the last sign concerns

and females).As asked to give more or less

reliable differences - I give drawings.In addition to different

forms of genitals, in violaceus the basal part of the genitals has

noticeable wrinkled microsculpture. Differences in the mustache

What is shown in the photo can also be a proskarabeus

they are informative. I decided to focus on violaceus based on what I saw - the color of the body and the sculpture of the (not quite clear) elytra, but

it can also be proscarabeus. I hope that my

doubts are quite understandable and will not be interpreted as

incompetence.
Second. About chernotelka. May Cerambyx forgive me, who has already been attacked so much - but I will add fuel to the fire. This is not tentiria. Those not only do not have such an indentation on the elytra, but there is no pronotum extended anteriorly. All of our employees have

voila, when determining in the photo. I admit it,

That it was a cursory move and I settled on

microdere, although they are habitually more slender. Only

Today I took a closer look at the structure of the architrave

- and the idea of one of the participants that this is Anatolica,

I don't think it's seditious at all. This is it (in my opinion). I think that

this is Anatolica (impressa Tausch.?).
Finally, people tend to make mistakes. And if

dear Cerambyx and wrong, this is not a reason to blame

his incompetence and poke his nose in "their" groups, and

just to explain how your position differs,

Dear Omar, With the same success, a person comparing

genitals based on my drawings and correctly identifying the T-shirt

can declare: "But you, my dear, are no longer the same.

You can't tell Proscarabeus from violaceus. Not

Do you want to play solitaire?".
Well, all of us should be careful with categorical statements, and check several times what we have to say.
With hope for understanding, and with respect to all.

Thank you, dear Milabris, for a balanced, painstaking and balanced assessment of what is happening (unlike mine, which is completely unbalanced

). I apologize to everyone for my bad and exalted temper. Sorry, friends! Really, I'm sorry! After all, we must all serve the truth, even though Plato is a friend. To be honest, my train of thought was similar to that of Mr. Milabris, except that I thought the black-calf was a species of Microdera deserta, not convexa. But now I am sure that chernotelka is definitely Anatolica, but I will not dare to bring it to the view from this photo. So my joy wasn't premature. But! Since it has already been said about the truth, we are waiting for Nabozhenko and hope that the KDG will fulfill its word and put the final point in our fundamental dispute. And you, Moustache, forgive me for being harsh - bad temper...

The pronotum is shaped like a tentiria, while Anatolyk's is completely different.. If this can be considered a difference in genera, then Anatolians fly
away Microdera deserta Tausch. similar, but still not the same.. - and the indentations are not very similar and the shape of the pronotum, elytra. There are no more photos of microderms on the Internet, so you can't really swing them.
my verdict is Tentyria elongata Waltl, 1839 (from what I found on the Internet

)
http://www.insectariumvirtual.com/coleopte...ia_Rincon_G.jpg It remains to check - if it lives where it should

, although the sculpture is a little wrong..
In general, choose the profane-elongata, dessert or what else..

I must also apologize! I agree with Mr. Omar that my language was inadequate in this situation. I was overreacting, I'm sorry

But as for belonging to Anatolica-still no, if not nomas, then rather another type of Tentyria...
Thank you Mr. Mylabris for the detailed answer

!
Upload pictures of my Tentyria again does not work, here is a computer without a floppy disk. I'll definitely post it tomorrow. By the way, my beetles still have an indentation, although it is weaker (in this beetle, indeed, the elytra are almost keel-shaped - as Ripper correctly noted).
However, in M. violsceus males, the antennae are still curved, even if this is not obvious from the green European part.
