Can you help me identify this elegant Conopidae : Conops sp. or Psychocephala sp.?
Thanks in advance!

As the "cross vein at the basis of cell R connects to the underlying cell at alf its length" I would say Conops sp. Snout seems to fit a Conops as well. :)

I will take a risk: Conops vesicularis. (I don?t see any silverish stripe at the sides in thorax.)

No, this is a Physocephala allright, the cell R is much longer than it seems.
The animal has no silvery stripe, but a yellow head above the antenna, that makes it Physocephala vittata!
greetings,

hmm... it would be better to view full and clear (specially apically)
wing venation to be sure. But if the cell R is really much longer, that would make it really a Psycocephala. :)

Thanks Jorge and Gerard! ;)
It's really difficult to make a non equivocal picture in natura! :(

this is, again, Physocephala chrysorhoea.
All still according to Seguy, I'm just working through his key.

OK. The silverish stripe is very fine but all is clear for me ! Thanks Theo! :)

Read 'chrysorrhoea' (double rr)

It is not P. chrysorrhoe but a species of the vittata group - I guess P. vittata s. str.
