Hi Max, yes, the kneeling tribal lady is definitely Drioli, the other nice set I like is of jazz musicians - including a very plump singer!
Here is an interesting site featuring the various Drioli miniatures - they reckon that the glass was made for Drioli on Murano, and I would expect that to be right, looking at the colours of the little animals.
I think I may have found your lady on the Drioli site Max - is it this one?
