hi flyforum,

from what I can see with this fly;

Basal antennal segments an base of flagellomere reddish/yellow (P.valida)
size > 10cm
2 prescutellar ac. (P. valida en P. errans)
no posterior setae: P. valida en errans

crossveins are a bit infuscated.
End of scutellum got a orange/red colouring

It is P. valida or P. errans but I don't know the differences..

Robert,

It is Phaonia valida : you can see that the apical part of M1+2 is slightly curved, and frontal triangle is short.

thank you Stephane, I see that apical part of M1 + M2 is slightly curved (see drawing) but where can I find the frontal triangle?

I looked in my book but did not find it..

Take care, M1+2 is an unique vein :
