There are strong proclinate setae on frons, so not a Phaoniinae. Hydrotaea dentipes is an interesting proposition, however from this picture, it is difficult to confirm (need to see the frontal triangle, here the M1+2 seems not conspicuously bent like H. dentipes...).

On the contrary, the halteres appear dark brown, not pale/yellow. If there is an ad on t2 and if apical section of M1+2 slightly bent forward, I think we can do a H. dentipes of this fly.

R4-5 seams slightly narrowed towards apex... mt2 has a pd, but on one tibia there are 2 seta above the pd and the other tibia has one seta above the pd.....? And the beginning of the haltera is yellow and the end is black. But I don't want to make it to difficult....so I think H.dentipes.....it must be!!
