United States: FL. Only known from two localities in south Florida.


Named after the Miami metropolitan area (also known as Greater Miami or South Florida), where the holotype locality is found, to highlight the great natural values of the area and to bring further attention to the conservation and appreciation of nature in south Florida.


See Notes above (under Diolcogaster ichiroi  ) for more details on the conservation value of these species. Both specimens of D. miamensis  were collected with Malaise traps.
