Most probably but I am concerned by the markings on tergite 2 not being confluent (markings can be more restricted in females, however) and the hind femora being black as females have orange/yellow hind femora.
This may be an unusual form and I just can`t see anything else it could be.
Usually placed in Platycheirus, subgenus Pyrophaena now but still Pyrophaena on BugGuide.
I have sent it to Dr. Martin Hauser and Professor Jeff Skevington....

Pyrophaena rosarum
I think this is rosarum. It just has more extensive markings on tergite 2 than usual. A quick note on the genus: We treat Pyrophaena as part of Platycheirus in our field guide. However, Europeans treat it as a genus. We had some molecular data supporting the European concept. However, we now have a very large molecular dataset (1100 genes) that supports its treatment as a genus. However, note that there are no morphological characters that allow the genus to be recognized (other than keying out the species separately). The bottom line - it makes sense to continue to recognize it as a genus as currently done on Bugguide.
