Hi,
I need some help with this Muscidae that was collected in the archipelago of Gothenburg.
Some characters that might not be well visible in the pictures:
Eyes bare. 4 postsutural dc. Prealar bristle short and weak, almost hairlike. Notopleuron and meron without hairs. 2+2 katepisternals. Scutellum bare beneath. Radial node bare on both sides of wing. Mid tibia with 2 posterior bristles. Hind tibia with 2 av, 2-3 ad, and 1 small pd near base.
