Can't really see the hind leg properly on this photo, so can't tell amounts how much of tibia is dark. Could mean hybridus can't be ruled out.
I agree with what Dave says, though you would expect a female hybridus to show yellow down the sides of the ocellar triangle, which this fly does not have, so pendulus is probably correct.
My Flickr photos...
Ian is right. The frons yellow dusting stops short of the ocellar triangle (the area containing the three simple eyes).
