Hourglass Fly - Rhopalosyrphus guentherii

Hourglass Fly - Rhopalosyrphus guentherii
Harris County, Texas, USA
October 9, 2016
Rhopalosyrphus ramulorum: based solely on the thumb image below. This subject has an additional cell or anal cell modification that R. guentherii does not have. This fly, apparently, is not to be expected in Texas, so I am passing it through ID Request for correction or comments.

Thank you.

I'm with Bob, but lets see what the Syrphid specialists have to say.

No additional cells
I would say that this looks more like Rhopalosyrphus guentherii, base on the positions of the cross-veins and the light streak in the marginal cell. Also, considering the location and the little orange waist-band.

That was my first impression,
but I am looking at the lightly shaded inner rear margin of the right wing that matches the upper wing in the thumb image and not the bottom. For some reason, that shaded area is not visible in the left wing.
