Aha - I can see that now - very helpful, thanks as always Frans!

Ptenothrix maculosa ssp. olympia
To differentiate maculosa from beta check the shape of the posterior dorsal patch.
In maculosa the patch is a longitudinal stripe.
In beta it is a rectangular raster.
This specimen is an interesting case : you can see the stripe, but in addition there are some extra irregular spots left and right of the midstripe.
