Hello everybody,

This is my first thread on this nice forum. :D
I need help to identify a little fly that belong to the Heleomyzidae family.

This fly as been catched on the ceiling of my flat located in the east of France

Annemasse, 74 Hautes-Alpes, France
Altitude : 435 m
Size: 4,5 mm (without the wings)
Date: 2011, March 26th

I tried to use an old identification key (Faune de france, Séguy 1934) that leads to a specie call Helomyza dupliciseta. It doesn't exist in Fauna europaea... Is there a synonym?

Thanks a lot for your helpful comments ;)
