 Dialineura doesn't have a frontal callus.
This one looks like a female Thereva spiloptera.

 The black spot in the frons, in your case it's divided into two circular spots.

Some examples of female Thereva.

 It's from Faune de France - Diptères brachycères, E. Séguy (1926)

Page 269.

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
