2. ???

It is possible that Enicospilus, but definitely not ramidulus - sclerites in the forewing are not visible

My joint. When I processed those images, I removed the sclerites, mistaking them for garbage.

Here is an additional photo:

Well done.
And now how to believe the photos?!

Is this also someone from the Tryphoninae ? Both are found in the same location. Sorry: the quality is not very good

But according to the new bourgeois fashion, it was possible to describe a new look...

From the series-and it happens
Previously, I searched the web for pictures of Cryptocheilus octomaculatus, Cryptocheilus octomaculatus, the first photos on this page are returned to the request.:
http://antvid.org/Vespa/Gal/Cryptocheilus%...omaculatus.html
However, both on the main photo and on several photos on the link " More photos and videos HERE = >"
pictured ... female wasp Parabatozonus lacerticida
The real female cryptoheilus is there in the last photo, anyone can compare and see how different the wasps in other pictures are in relation to this wasp.
Because of these photos, I was forced to spend three hours figuring out what was going on

According to the last link - there are 3 species, the first three photos are Parabatozonus lacerticida, the fourth is Cryptocheilus sp. (not a male Parabatozonus lacerticida, since the whiskers are black, not orange),and the last one is Cryptocheilus octomaculatus, which looks like a female. I caught this in the Crimea on the coast in the village. Vitino, here it is:

By the way, if we talk about the last photo, then if we compare it with European discussions in which this type is indicated-kr. octomaculatus, then this 4th cryptoheilus to put it mildly is not very similar to them. The fact that cryptoheilus-yes, but eight-point-maybe not a fact There is just a very similar number of such types.

Who is the author of the photos and who determined them-is available on the site.

I am tormented by doubts that V. L. Kazenas (written on the first photo) could identify a perfectly detailed female lacerticida as a cryptoheilus.

That is, Vladimir Longinovich sent you a photo of an unidentified insect for posting on the site, entrusting your team of "experienced specialists" to identify it independently and stick it wherever they want, signing it with his name? It's a good thing he doesn't look at your site, as is clear from this situation, otherwise he probably would have regretted such an act three times if he saw where you put his photo. I am sure that he himself knew perfectly well at the time of sending who was captured in the picture, the case is quite simple even for a non-specialist in pompilids.

If you want to understand something-turn on your head and read the site, Ilya, and do not engage in writing fantasies. This site is not for them.
