Topic: Merzomyia westermanni / Icterica westermanni (Diptera, Tephritidae)
I notice the NBN gateway has records (different sets) for both Merzomyia westermanni (Meigen, 1826) (commented = Trypeta westermanni Meigen, 1826) and Icterica westermanni (Meigen, 1826). From the discussion in Korneyev (1995) these are clearly the same species, and need to be combined (as Merzomyia, if Korneyev's work is accepted).
