Not easy from this pics.
Could you take a picture of the fossula in mid tibia?
Could you dissect the male genitalia?

Thanks

Hi, Paolo.
I can take photo of the fossula through a microscope later, then go back to ID.
I never dissected the male genitalia of chrysidids and I do not know how to do it.
Best regards, Vladimir.

Hi Vladimir,

It's very simple.
By using the microscope, insert a pin (0, 00, 000) between the last tergite and last sternite and bring out the internal segments. Inside this "packet" you find the genital capsula. Remove it from the rest of the internal urites and glue it on a label. Don't throw the internal segments, they could be important in the future.
That's all.

Waiting for the pictures.
Ciao
Paolo
