Sure looks like it. I suppose we'd have to check all those other species associated with Lycium to see if any others make galls like this, before labeling this Aceria kuko. For future reference (in case that link goes away), the other species recorded from Lycium are A. caulicecis (Keifer), A. eucricotes (Nalepa), A. kendalli Baker, A. macrodonis Keifer, A. pallida Keifer, and A. wagnoni (Keifer). All are recorded from the USA, unlike A. kuko.

If these are arthropod galls,
I would guess they are midge galls. If so, they're not in (1). They could be caused by fungi or bacteria. If you find them again, I would try opening some up to see if there are larvae inside.

 
My
'Aceria' guess came from seeing this:

But I will look for them again this year.
