Description. Different from P. zonata as follows: Male. Body colour more variable: Newly emerged males are wholly yellow except blackish on upper occiput, postpedicel and tips of mid and hind femora, but they turn darker by age and gradually attain a darker body colour resembling that of male P. zonata . Antennal scape, pedicel and sometimes narrow inner basal part of postpedicel bright yellow. Entire palp yellow. Setation on postgena all golden yellow. Mesonotum with a distinct shine through thinner greyish dusting. Legs, including tarsi, yellow except for well demarcated blackish tips on mid and hind femora. Abdomen with median dark stripe very narrow or even absent. Contiguous parafrontalia extremely narrow, separating eyes by less than half transverse diameter of anterior ocellus. Mid tibia with submedian ad seta very reduced or absent. Hind femur ( Fig. 8 ) with a row of 5‒7 av setae and 1 pv seta near middle, all erect and strikingly long, about 2‒ 3 x as long as depth of femur where situated. Terminalia ( Figs 34 , 43 , 52 , 61 ): Most similar to those of P. scapularis and P. ringdahli , but shape of surstyli, postgonite and distiphallus clearly different. Female. Legs, including tarsi, yellow except mid and hind femora as a rule narrowly black-tipped. Setation on postgena all golden yellow. Oviscapt ( Fig. 74 ) shorter and with broader sternite VIII pieces, agreeing with description given for P. scapularis except: Hypoproct broadest basally, with 4‒5 apical setae and a few discal setulae; cerci more slender in broadest aspect.

Distribution. PALEARCTIC. Northern and central Europe from Britain and southern Fennoscandia in the north to the Pyrenees ( France: Hautes-Pyrénées; Spain: Gerona) and the Alps ( Italy: Bolzano) in the south. Northernmost record is Russia: Murmansk, 40km S Monchegorsk (new record).

Biology. Ståhls et al. (1989) have reared this species in southern Finland from Leccinum sp. ( Boletaceae ).
