It certainly is and what a surprise.
The male brand reaches vein 1b closer to the wingbase than the termen.
So it is P. mathias after all.

I am not sure whether the upperside shot could be used accurately to compare lengths of two line segments on the wing as the right forewing might not be all within the same focal plane of the camera at that time.

The wing base could be further away as compared to the termen from the focal plane.

You have a point there. There is a perspective distortion here where the outer part of the forewing nearer the camera appear longer than the part towards the wingbase, looking along vein 1b.

So, it could still be P. agna.
Unfortunately there are too many confusing images on the net to make a proper comparison.
