It looks like the Rabdophaga rosaria to be found in the gallery (http://www.dipter...to_id=2653).

I looked on FE about those Cecidomyiidae (whose group coordinator is Paul Beuk himself) and didn't find any R. rosaria. The author of the picture told me that R. rosaria should be R. strobilina (Bremi, 1847). Does this hold true?

On the Internet, one can often find IDs like Rabdophaga (Dasineura) rosaria for this gall. In FE, Rabdophaga and Dasineura are different genera. Did it change recently?

Skuhrava (1986) treated Rhabdophaga as a synoniem / part of Dasineura. Later publications of Skuhrava dit not follow this concept.

Gagne (2004) treats R. rosaria as a synonym of R. strobilina.

According to Skuhrava & Skuhravy (2006) R. strobilina is a seperate species. I have only an abstract of that article, therefore I do not know their motivation.

Roskam (2009) mentions R. strobilina as an inquilin of galls of R. rosaria.

In Cecidomyiidae it often occurs that synonyms are defined on bases of the galls. Research may proof that some species are inquilins living in the same galls.

Your picture shows the gall of R. rosaria and maybe R. strobilina lived in it too.
