My first impression is subfamily Steganinae.
Edit: ...but the basal scutellar bristles are convergent.

Now I'm considering Ephydridae but I still can't place it.

I'm not familiar with the genus, but I'm wondering whether the dark costal margin of the wing on this specimen best fits
Guttipsilopa.

Should it be
Guttipsilopa, it would seem to me most like
G. dianneae as described by Wayne Mathis regarding the wings: "Wing generally lightly infuscate, anterior margin conspicuously darker brown, area along veins and crossveins slightly darker, transition from dark anterior margin to lighter coloration gradual but limited to a narrow zone." However, I am not great at interpreting morphological jargon and have little experience in attempting to key and identify based on complex features.

Reading Mathis' paper, I see the nearly indistinguishable
Guttipsilopa umbrosa is known from Florida.

There are two species of
Guttipsilopa (Nesopsilopa) in Florida and I suppose you probably have one of them. See
Mathis, Wayne M. and Amnon Friedberg. 1980. A New Species of
Nesopsilopa from Florida (Diptera: Ephydridae). The Florida Entomologist 63(3):279-281.
