Tony, I don't think it is Ph.brunnipes - it has long mid-frontal stripe, almost till anterior margin of frons. Also brunnipes has contrasting dark forelegs.
My impression is Pherbellia argyra - whittish foremargin of frons, short mid-stripe. Also it iseems to me that image N2 shows rather long plumose arista.
I'm not 100% sure, still...
