Moscow region, 23 aug, 4-5mm.
Female of Phasia obesa?

---

I'd say so, but you know what my record on Tachinidae is like! :p

---

Late summer is good time for bad Tachinist, grace to somehow recognisable subfamily Phasiinae!
:D

---

Well, I see only 1 row of bristles on the parafrontalia and the genitalia suggest pusilla, so my guess would be pusilla


Theo

Theo, halteres are yellow!

---

Theo - I thought that the ovipositor in pusilla curved downwards - have I got it wrong? :|

---

parafrontalia & genitalia

---

I'd go with P.obesa (female) - yellow hairs on the gena & yellow haltares :D

---

Maybe the first picture fooled me ?
The shape of the tip of the ovipositor is not like obesa, there is a downwards oriented 'pin'-thing. Or is this something behind the ovipositor ?
The halteres seem to be yellow, though very out of focus, I'n not sure.
The genitalia resemble most Ph. pandellei.
However, I am not going to give such an extreme ID on a photo, not matter how good the effort, Nikita.

So, let's wait for the specimen.

Thank you Theo.
OK, you'll get speciment mid-september. I have to say that this time I'm 100% sure, that 1-st and 2-nd photo are of the very same fly.

Hi Nikita,

I noticed this summer in Siberia that Russian have a good sense of humor!

I only just noticed your left new picture.
It is clearly not subgenus Hyalomyia, so all my contributions are wrong.
Except for the part that I might have been misled on the genitalia in the first picture.
So it should be obesa, chris was right all along!
Still nice to have a look at the real material.

Theo, your authority is so doubtless, that if once you tell that elephant is Tachinidae we all have to believe it!

I have said it before: keep checking !
thanks guys

(and IDing Tachinidae remains one of the most dangerous professions on earth !)
