Found this fly near a riverstrem, Southern Sweden yesterday

Is chrysogaster correct?

Hi Martin, Chrysogaster should have red antennae - these and Melanogaster small and rounded flagellum. Orthonevra intermedia? (André Schulten: Fotogids Zweefvliegen)

Yes, I agree on Orthonevra intermedia/stackelbergi. Which of the two spp. apparently depend on genital details.
