Hi Jaqueline,
I am going to try and help with this one,
from the way the eyes set I think that it is Sitticus spp
and hazard a good guess at S.Floricola
I use this site for the eyes which should lead you to Genus
Spinnen van Belgi - Araignes de Belgique - Spiders of Belgium
your photos are good from the side, front and three quarter on, But to get an ID
to species reqires a more detailed study of the epigyne in the case of this female, (or the palps if it's a male)
Don't take my ID as gospel, I am trying to improve my knowledge by helping others, some times I'm right sometimes wrong so wait for anther persons input and keep posting the pics,
Duncan
