Paul, thank you. I'm not a specialist in Diptera, of course. But the proportions of body (not colour) of this fly more resembles Cephalia. Can it be come species of Cephalia, for example, and not Ulidia?
Besides, the Ulidia's I find in the Gallery, they are brilliant, and this fly is matt black?

Pavel, thank you again. I did not find images of other species of this genus, and this fly is really black. Yes, let's wait.
