Hello,
Could it be Helina annosa ?
The chaetotaxy of the legs seems to me to be consistent with what is expected for Helina annosa:
- ventral setae of hind femur present only on the apical third and shorter than the width of the femur.
- foretibia with a posterior setae
- middle tibia with 3 to 5 posterior setae: OK (at least 3, the third one is blurred, difficult to see, picture 4)
- hind femur with front setae on the apical half
- ♂ hind tibia with 6 to 10 front setae and 2 to 4 rear setae and a row of posterior setae: OK (at least 6 front, at least 2 rear, row of p setae)

Hello. Well, in my opinion there is H. evecta and several doubtful species which are probably synonymies of H. evecta: H. annosa and about 15 Chinese species.
Your fly is H. evecta or some of their synonymies if I'm wrong.
