Probably none !
Holzschuh (2003) compares his species with P. multifenestratus and writes nothing about Xylotrechus savioi (Pic, 1935) (Holotype here).

Nosense! This species has nothing to do with P. intersectus.

I'd not be so categoric: the basic pattern is strangely the same and we do not known the variability of Xylotrechus savioi.
Only legs seem to show a different colour.
I'd curios to see a frontal view of both species...

Apart the colour of the antennae, the ridge is a bit different.
Might be a sexual difference?

l'échancrure des yeux me semble identique (dérive de la position).
la pilosité vertex c'est un artefact
