Sericomyia - Sericomyia chalcopyga - male

Sericomyia - Sericomyia chalcopyga - Male
Lostine River, Wallowa County, Oregon, USA

Sericomyia male. Could this be S. chrysotoxoides? It just doesn't look like the S. chalcopyga I've seen.

Moved from Syrphid Flies.

Sericomyia chrysotoxoides is
Sericomyia chrysotoxoides is more eastern and has the front margin of wing more darkened. The Sericomyia are being reviewed and they are thinking there may be three more species. The markings on tergite 2 are too oblique for chalcopyga. I have sent this to Doctor Martin Hauser and Professor Jeff Skevington.

Sericomyia chalcopyga complex
This is outwardly like S. chrysotoxoides but I agree that it is not. We do have a handful of western records for chrysotoxoides (that need to be re-evaluated) but new data show that S. chalcopyga is a complex of 3 or 4 species. One species is very common (hopefully this is true chalcopyga but we will not know until everything is worked out) and the others are all rare. We don't have males of all yet which is why we are not yet in a position to describe them. If anyone gets males of these different looking Sericomyia chalcopyga group species we would appreciate specimens to support this work. Please contact me if you obtain any specimens. For now, I would treat all of these chalcopyga things as chalcopyga complex.

Thank you for this detailed i
Thank you for this detailed information! I thought it looked a little off for S. chalcopyga. I'll be curious to see what comes out of the revisions.
