You have to be a bit careful using Belshaw because he describes the wrong vein but figures the correct bit. Go by figure #394, which I believe should have been called something like "the section of the costa between SC and r1" - I think your photos are focused on the section of the costa before SC. But in the top right of the first wing it does look as though the correct bit of wing has the extra hairs ... so you may be right :D
