Eyes bare, reniform. Antenna with 13 flagellomeres, exceptionally with only 6 or 7 flagellomeres ( P. uliginosa , Fig. 25 ); AR = 0.29–0.90; frontal tubercles minute or absent. Wing covered with macrotrichia on almost entire area (excl. P. wagneri ), number of macrotrichia below An, length of RM, distance between RM and FCu and shape of anal lobe species-specific ( Figs 1–7 ). Tibial combs of mid and hind leg fused or slightly separated, if widely separated - number of teeth reduced; each comb often bears single, slightly longer, spur-like tooth.

Superior volsella triangular with anteromedian margin straight or convex, or with slender apical prolongation and anteromedian margin concave ( P. m e n d l i ), and/or sinuous ( P. styriaca ); tubercle at base of superior volsella bearing Micropsectra -seta sensu Säwedal (1982) usually tall and cylindrical, exceptionally short and conical ( P. mendli ). Digitus never extending beyond superior volsella or absent ( P. styriaca ). Inferior volsella species-specific ( Figs 32–41 ). Median volsella usually with spoon-shaped or with falciform lamellae ( P. u l i g i n o s a , P. wagneri ). See also taxonomic remarks.
