Helen’s twins in the Balkans: discovery of two new Paraptychoptera Tonnoir, 1919 species closely related to P. helena Peus, 1958, with systematic revision of the “lacustris” group (Diptera, Ptychopteridae)

Ptychoptera castor Keresztes &amp; Kappert, sp. nov. and P. pollux Keresztes &amp; Török, sp. nov. both belong to the subgenus Ptychoptera (Paraptychoptera) Tonnoir (1919) and are described from boggy headwaters in the south Balkan area. These new species are closely related to the r...
