Austin, Texas. I was photographing something else - happened to spot this fly on one of the photos.

I processed the image to enhance wing venation and rotate it to match the images the indocument. Result here.

There are two species only that are found here. The document I linked says, among other things, "Wing with cross vein r-m always in basal half of cell dm and prior to intersection of subcostal vein in costal vein (see previously linked document for illustrations)." for
reversura. For
orientalis it says, "Wing with cross vein r-m beyond middle dm cell, as well as beyond intersection of subcostal vein in costal vein"
I've marked up the second image here to try to show the relationship of rm to the intersection being referred to. To my eye, it appears to match
reversura better.
Palpus and setula are no help. I just noticed it also mentiones setulae on the fore tarsi, which are in focus in my image. However I don't see a comparison image of tarsi in the document: "fore tarsus with only normal vestiture of short setulae" for
orientalis. "fore tarsus with moderately long anteroventral and posteroventral setulae on tarsomere 1" for
reversura. I don't know what would be considered normal vs. moderately long.

I have not remembered which Atherigona were introduced in America. If the choise is between orientalis and reversura, it is
reversura!
