In southern Florida, females can only be separated from the closest look-alike species, Tachytes seminole, with a clear view of the pygidial plate. (dorsal surface on the apex of the abdomen) (1)
The males may be separated by the number of pale abdominal bands. The males of T. seminole have three pale bands.
Here is an example image of a female from Florida: ♀ dark coppery brown pygidial plate (vs. bright coppery in T. seminole)
