if the following keys are accurate, then you have a photo of versicolor:

Parhelophilus versicolor
Occiput entirely yellow pilose
face profile convex
costa with extensive golden pile basally, extending beyond humeral crossvein

the hairs in the area of the occiput are entirely yellow/golden.
Parhelophilus versicolor

I have no idea why noone answered your question. interesting. I hope that you have a pleasant day.
