It was the end of the day and I notice that all the flies were searching for a place to sleep inside cracks in a stony area. Almost any crack I checked contain a fly standing backwards with it's face to the exist.

Great pictures !
It's not a Rhinohorid, but a Tachinidae, clearly in the tribe Wagneriini.
Difficult group, but pictures are quite good.
It's either Wagneria or Periscepsia, I'd say is Periscepsia, in which case it can only be P. handlirschi. I'm not sure if it completely fits this species, need to check my collection.

Zeegers,
I'd collected one sp. so if you need me to check anything it is possible.

Ok.

Do you know the humeri, the 'shoulders' at the front of the thorax ?
Question: are there either 2 large bristles on each humerus, 3 in a straight line or 3 in a clear triangle ?

There seem to be 2, also another feature is not consistent with Periscepsia. So it is Wagneria. Very difficult genus.
I have little hope we can ID to species level. But I'll give it a try.
