The yellow (often brown) mesonotum is the character of stylatus/limbardae, which can be easily recognized also from long oviscape and smooth aculeus of female; all these flies look quite similar to stylatus, longirostris, eximia and inulaedyssentericae, but their geographic variability and host plants remain poorly understood.

Please keep on collecting by rearing from the host plant galls, it could give some progress to this study.
