Moved from Dasysyrphus.

Thanks, Kelsey!

I think Dasysyrphus intrudens
I think Dasysyrphus intrudens species complex, using the new Locke and Skevington Key (Zootaxa 3660, 2013), though I also briefly considered D. limatus.

The maculae appear to reach the edge of the abdomen, maculae on tergite 2 are not large (but limatus' markings on tergites 3-4 are completely different than this fly), and the maculae on 3+4 fit the description of the intrudens species complex better than they fit venustus (venustus is described as the maculae being unconstricted, more oblique than lunulate/arcuate, and not having swelling on the medial end). D. limatus maculae on T3+4 are transverse, unlike the curved maculae on this fly.
