Looks like Phaonia halterata, but please, answer to these questions :

Posterodorsal present on distal third of hind tibia (Phaonia bristle) ?
Arista only pubescent ?
3 postsut. dc ?
No strong presut. acr ?
Prealar short or unconspicuous ?

Ok, everything seems to match. Phaonia-bristle is there, arista is only pubescent, 3 postsutural dc, no strong presutural ac and prealar seta is very short and tiny :).
