Nope, not Ulidiidae. It's Opomyzidae, something like Geomyza sp.
I'm sure Jan Willem can tell us more!

Gerard is right it is a specimen of the genus
Geomyza [Opomyzidae]. My best guess would be a female of
Geomyza martineki, but sternite 8 should be studied to get a positive identification. If you really want to know the identity of species like this, you should collect specimens.
