Hello, this male of Calliphoridae was not photographed from a very simple angle for determination, sorry.

If the general appearance and what we see of the curvature of M1 are reminiscent of a simple Calliphora, the colors of the "beard" and the spiracle do not seem to correspond (we should see orange...). What do you think?

Thank you for yours answers

Luc

Hello Luc, as far as I can see it could be a male Bellardia sp. or Onesia sp.

Yes, looks like an Onesia, doesn't it ?

Indeed, it does - I just wasn't sure about the 0+3 ia-bristles.

Thank you for your answers. I have the impression that there are 1 + 2 ai, which I tried to render here by changing the contrast of the photo and marking the bristles that I imagine are concerned in red.

On the insect.org forum, a proposal was made
"Bellardia viarum male
1. femur 2 without a preapical seta. (Calliphora a is present)
2. 1+2 ia (Onesia 0+3)
2. discal setae on t4 visible in photo 2."

Third antennal segment seems simply too long for Onesia. I find it very difficult to assess the humber of IA, in any case prae IAmis unstablemin Onesia.

Thank you, we are making progress by formally eliminating Onesia.
For the number of AI, is it more complicated than what I pointed out in red? Maybe on the number of AI before the suture? Does Bellardia viarum seem like a good hypothesis to you?

Well, between your first two red dots, there seems / might show a broken off bristle, which would be the first post IA out of 3 .....

So, I havent ruled out anything

I see, thank you!
And are there other possible genus that would have a 1+3 AI formula?
