Thread subject: Diptera.info :: small black calliphorid (?)

Hi,
Recently I took some photos of a small black fly that were all of (semi)bad quality, here are the best ones. As to black calliphorids, I know Morinia doronici and Melanomyia nana only. The first doesn't fit, and I am afraid neither does the second. Melanomyia seldom folds its wings that way (well, that might not be important), and in my fly the wing veins look infuscated (or is it a matter of the light?). However, I cannot remember that Melanomyia has short hairs between the thorax bristles. So I'd like to ask for help!
Many thanks, Sundew

I have had a look, and I think it is a male Morinia doronici : the bristle arrangement on scutellum does fit as for the infuscation of wings. I think we can guess also the band of whitish dusting across the pleurae (from katepisternum to notopleural depression).
I can be wrong of course...

When I took the photos, I thought: another Morinia male. On the screen, however, they raised my doubts. Till now I had only dorsal views of males (that always sat flat to the ground) and never seen the abdomen. As the abdomen of females is short-haired and shiny I did not expect the males to be thus hairy! This was probably a wrong train of thought, smooth females and hairy males are obviously widespread :D.
Ok, Morinia then. Many thanks.

I agree with Stephane.
Melanomyia has smaller apical scutellars and less darkened wings.
It tricked me, though.
