Ptychoptera castor Keresztes & Kappert, sp. nov. and P. pollux Keresztes & 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 range-restricted P. helena Peus, 1958, which is known only from Oiti village, Mount Oeta, Phthioitis region, Greece and, together with P. lacustris , forms a morphologically well-defined unit in the subgenus Paraptychoptera . Based on cladistic analyses of 53 different morphological characters using the male antenna, wing, and genital structures, a general revision of the “ lacustris ” group is proposed with a dichotomous key of Paraptychoptera species.
