Like you, I have not seen S. sinaiticum in the field - but I would be happy to call this one sinaiticum if I came across it.
The strong dark bar on the side of the first abdomen segments, generally pale appearance (but with more black than would be expected on S. meridionale), and blue-grey underside to the eyes all point to this being the correct ID in my opinion.

HI Odonate
From the few images of females I've found I think they're ok for sinaiticum
e.g.

http://www.fotonatura.org/galerias/fotos/415207/
but without field experience it's always a bit difficult to know..

I would expect at least some colour to be visible in the wings if the subject photo was fonscolombii, and for the front and rear borders of the pterostigma to be more distinct, despite the dragonfly being fairly recently emerged (based on the white colour of the pterostigma).
Usually fonscolombii tend to have more complete dark lines on the sides of the more distal abdomen segments, and a less distinct dark bar on the first to third segments as well.
