Greetings,

I'm seeking your advice on this determination.

I first thought this fly to be Pandivirilia eximia (Meigen, 1820). Then, a member of the Insecte.org forum pointed out to me that, according to the determination key of Van Veen (which I was not aware of), P.eximia should not have a hairy face.

The key leads me to :

22.a. Tergite 4-6: lateral margin entirely shining black; thoracic dorsum with two yellowish grey longitudinal stripes and two pairs of dorsocentral bristles. 9-11 mm. -> Thereva cincta Meigen

Your opinion would be greatly appreciated (click on the photos for enlarged view).
