Hello! I found this today (February 13) in Austria, the height was 1,73 km approximately. I think, that this is a Calliphoridae species. So, thorax is blackish, abdomen is dark green, and arista is clearly hairy. Please, could you help me to identify this species?

Hi, it's a demanding one! I think it's a Protocalliphora sp. but I'm familiar with P. azurea only - which does not match. I guess it could be a male P. peusi.
(based on "Blow flies", Olga Sivell and "Blow flies of Fennoscandia", Knut Rognes)

Hello! Thank you very much! I expected Protocalliphora as well, but I had a problem with it. About my key, Protocalliphora has acrostichal bristles in the thorax, but in this specimen, I don’t see them. About my key, the genus Protophormia doesn’t have acrostichal bristles, but, the only species what occurs in Austria is terranovae, and this is surely not terranovae. Or did i miss something, and is there Protocalliphora with acrostichal bristles? Or P. peusi is a species, what doesn’t have these?

Greetings, Nimród

Hello Nimród, P. peusi has acrs, too, and we don't see it. That led me to Protophormia firstly. The other Protophormia, atriceps, is an arctic species and is similiar in colour to terraenovae. Your image 4 shows the wings in a typical Protocalliphora fashion and the frons could be "twice the width of the ocellar triangle".
On distribution:
Rognes: P. peusi widely distributed in Europe (Peus, 1960, Schumnann, 1986)
Sivell: P. peusi in A, CZ, SK, DE... (Draber-Mońko, 2004)
Do you have more images (tibia 1 and 2 face with flash)?

Hello! Thank you! I have some pictures about tibiae:
First tibia:

First tibia as well:

Second tibia:

Thanks, but unfortunately the resolution is not good enough to see the hairs on t3 or if there ae 1 or 2 pv bristles on t1.
I've recognised another character in the Rognes key to point to P. peusi (plus others that don't appear in Austria): "Calypters, including morgins, rather pure white.
But after all, it's not enough to name the species with confidence, I think. Especially because no acrs can be seen...

---

In picture 7 I see the white calypters. But, I understand if it is not enought, to name this species.

Thank you very much for your help!

Why not a Bellardia?

---

As far as I know, Bellardia's frons is distinctly narrower and they hold there wings in delta-style like the other Calliphorinae.

---

It cries out Protophormia all over to me - which makes also more sense given date.
Yes, the calypters looks white, but they can seem quite light from a distance in Protophormia. And ACR are lacking, as already observed by all of you.
A close-up of the calypters might help.

Hello! Thank you! I’m sorry, but I have just this from the calypter, in this picture they are maybe visible. So, if this is a Protophormia sp, why it has as black colour? Because I haven’t seen any Protophormia in the internet, what has as dark and blackish colour. Or is this maybe an abberration?

i’m not sure which pictures you are looking at, but Protophormia ismuch darker than (most) Protocalliphora.
For instance

and these calypters are definitely not white ….
