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)?
