Hello

though I don't know even the family for shure, I woud be glad if identification of the species is possible from this only photo.

Greece, Peloponnese, near Sparta 36.98043°, 22.42267° length at about 400 m high at 8. June 2016

Thank you very much

Difficult to see, looks like a Nemestrinidae. Fallenia is not uncommon on the Peloponnesos. Definitely not a Tabanid, might be a Bombyliid.

Not Bombyliidae, the "diagonal vein" is unique to Nemestrinidae.

---

Following Fauna Europaea there are only 6 species of the family in Greece
Nemestrinus reticulatus
Nemestrinus graecus
Stenopteromyia bolivari
Hirmoneura obscura
Fallenia fasciata and Neorhynchocephalus tauscheri

But regarding the gallery I think this is the end of the road.

Thanks, Siga

I cannot see venation well enough but this creature fits Neorhynchocephalus tauscheri rather nicely ;)

---

Yes, I thought I saw a "diagonal vein", but was not totally sure, since it is slightly out of focus.

Nice find !

I don't know the customs in the Forum well enough nor the members.

Can I take Neorhynchocephalus tauscheri for shure? And shall I change the name of the thread to that name? And shall I use the the button ''Add this attachement to family...''?

Thanks for answer,
Siga

Well, I am not an expert in the strict sense of the word (I only have been into Diptera for 6 years) but Nemestrinidae is one of the families I work with. As far as I can see in your picture, it is that species. I would be happier if I could see a frontal and a lateral view, of course. Then I would be able to confirm. But still I think it should be. I cannot think of another species that matches your fly.

OK, I have gone to the literature and studied carefully what I can see of the venation of your specimen. And I see the diagonal vein reaches the margin of the wing. I'd wish somebody else can confirm and I see correctly. This and some other small peculiarities makes me think that it could be Hirmoneura. However I have seen pictures of Hirmoneura obscura and this species doesn't look like your fly. That is why I ruled out in the first place.

Really, with only this picture is very difficult to be completely certain of the ID...

EDIT: Well, I am starting to be really convinced this is Hirmoneura obscura. I have re-checked the venation and really fits :) See attachment. Also legs fit better than N. tauscheri as does the darkening in the frontal part of the wings. Body colour looks odd (perhaps because it is a female and i only know the male?) but morphologically fits truly well :) By the way, H. obscura is the only species in Europe.

---

If it is possible to identify the species with the venation only, I extracted from the original photo that part and sharpened the differences. That makes the photo in all ugly, but the former dull parts are well visible.

---

Siga, no shadow of doubt now: Hirmoneura obscura :) Excellent!! |t

Thanks a lot, I've put the photo to the gallery
