I've added two more photos on which can be seen midfemur with 5 anteroventral and 3 posteroventral bristles and hindfemur with 4 anteroventral bristles which should make it Norellia tipularia according to "Norellia spinipes (Meigen) in the Netherlands and its distinction from N. tipularia" (Herman de Jong, 1985). Is this correct?
