This appears to be in Fanniidae based on the spacing of the Sc and R1 wing veins. Of the 4 genera in that family, I think this one’s a Fannia. The photos don’t show the A1 and A2 veins well but I think that Euryomma can be ruled out by the fact that the first presutural dorsocentral bristle appears to be >1/2 the length of the second (1). The aristae aren’t plumose so that should eliminate Piezura (1). MND lumps Coelomyia with Fannia and Platycoenosia with Piezura (1).

All of that “logic” could be completely wrong so I’d appreciate confirmation or correction of the ID. Thanks in advance for the help
