Hi all This Phaonia has me a bit baffled. At first I thought it was subventa, but it has crossed interfrontals, prst acr, dark scutellum and weak infuscation along most of the veins on the wing. I swept it from low vegetation in mixed forest where it flew alongside numerous genuine Ph. subventa. Perhaps I should be able to key it myself having the specimen and all but it won't fit. So I was wondering if any of you have an idea about what species it might be. Caught 26. iv 2014 in mixed forest not far from Copenhagen. Size much like Ph. subventa. 4 shots.

Hi Walter, this is definitely a female Phaonia subventa : crossed inter-frontal and prac are OK for this species. The crossveins can be more or less insfuscated too. The arista short plumose, the t1 with p. seta, the flatened palpi in female and the abdomen often darkened on midle are other typical characters.

Thank you, Stephane! I was afraid I was beginning to loose it  As a matter of fact I don't recall ever having seen a subventa with those characteristics. The ones in my collection are all "normal", without interfrontals, with yellow scutellum and in females with hardly any dark midstripe on the abdomen.

Ph. subventa has always 2 pairs of prac and almost always crossed interfrontals, however it seems to be a particulary dark specimen it's true.
