Torymus sinensis has been introduced in some European countries to control the infestation of the Chestnut Gall Wasp (
Dryocosmus kuriphilus), but other parasitoids have been reared from these galls, so I am not sure about the species here.
Gall found in a park in Vienna, kept indoors. Wasp hatched in early January
