In the mean time I can tell that the venation does not look at all of what I've seen from Cecidomyiidae, there's no gap in the costa at the top of the wing, it has five tarsal segments (of which the first is not very small). Following the table of Oosterbroek, Scatopsidae would indeed be my best guess, but it doesn't look like one (?)
