Syrphidae  - Syrphus - male

Syrphidae - Syrphus - Male
Monteregie County, Quebec, Canada

I always thought this one was Eristalis transversa but I now have doubts, Can you help?

Moved from Syrphini.

Syrphus ...... male.
Eristalis have the R4+5 vein strongly looped.
The yellow markings overlapping side margins on tergites 2, 3, and 4 and narrowing abruptly just before side margins, separate this from Eupeodes.

Moved from ID Request.

One quick way to usually rule out E. transversa is the lack of horizontal band across top of thorax.
