Note. Marchal (1900) mentions Eurytoma rosae Nees, 1834 in Biorhiza pallida ( Olivier, 1791) (S). Eurytoma brunniventris Ratzeburg, 1852 is much more common in oak cynipid galls, and E. rosae is much more common in rose cynipid galls. These two species can be confused and consequently, Marchal’s mention may have corresponded to A. brunniventris .
