Cecidomyia, Perrisia bergrothiana. D. bergrothiana has long been understood as a synonym of Jaapiella floriperda, but has been reinstated by Skuhravá & Skuhravý. An argumentation is not given, neither is information given about an eventual distinction in the galls of the two species. For the moment is must be assumed that the two have different host plants.
