Danish species per municipalities.

       
Small Pincertail (Onychogomphus forcipatus)
Denmark
Status: The only Danish records of this species are from Susåen near Herlufsholm, Næstved. But they date back to 1908 and 1936 (https://www.naturbasen.dk/observation?id=1488889), but without knowledge about any established populations. Taking the healthy Swedish population into consideration, however, it might not be unrealistic to hope for a Danish re-discovery one day - Bornholm being a likely bet.
