Collected at UV light.
I believe this is Cercyon floridanus (small size, dorsal microsculpture). Unfortunately, Epler (1)
only discusses two of the species and I don't have a copy of Smetana's revision of the subfamily, though the genitalia of this male does match the figure in Epler. Otherwise, the only species on FL checklist I haven't excluded are C. crocatus and C. nigriceps (haven't found any info on them online).
