( Fig. 9 A – D ; Plate I, Fig. II) Locus typicus : USA , Pennsylvania , Spring Brook. Holotype : Male , 1945, leg. F. R. Shaw ( PWMP ). Paratypes : 2 males , same data as holotype ( PWMP ) ; 1 male , 30.iii.2002 , USA , Alabama , Baldwin County , Byrnes Lake , 30.47°N , 87.54°W , Malaise trap , leg. J. W. McCreadie , ( PWMP ) . Description . Male. Head : Round; eye bridge 3 facets wide. Antenna brownish; 4 th flagellomere with a l/w index of 2.0 and pale hairs as long as the diameter of the basal node. Palpi 3-segmented, rather short; first segment with 4–5 bristles and a flat patch of sensillae. Mouth parts short. Thorax : Brown, scutum with long dense hairs. Scutellum with 5–6 robust bristles. Postpronotum bare; mediotergite sometimes with a few short bristles. Wing brownish; R 1 nearly as long as R; c = 3/4 w; y = x, x bare and y without or with a few macrotrichia; M-fork as long as M-stem, narrow; CuA-stem shorter than x; posterior veins distinct and without macrotrichia. Haltere short, brownish. Legs brownish; tibial organ of the fore tibia not visible. Claws toothless. Abdomen : Tergites rather long and densely haired. Ventral base of hypopygium with a large intergonocoxal lobe, covered with long dark bristles. Gonostylus short, broadly oval, apex densely haired; subapically with 2 short dark spines, not longer than the apical hair and with a longer whiplash hair. Tegmen somewhat broader than high, apically rounded. Aedeagus short and robust. Body length: 5 mm . Comments . The species is characterized by having a large intergonocoxal lobe covered with long dark bristles. It is similar to Psl. jucunda regarding this character. It differs from it by having shorter apical spines on the gonostylus, long fine bristles on the basal lobe of the hypopygium, a differently shaped tegmen and bristles only in the distal half of the ventral side of the gonocoxites. The specimen from Alabama differs from the two specimens from Pennsylvania regarding the setosity of the basal lobe of the hypopygium. In this specimen nearly the whole surface is covered, whereas in the other specimens bristles occur at the margins only and the mediotergite is without short bristles. The small number of specimens currently known to us does not yet allow us to establish another species. Distribution . USA ( Alabama , Pennsylvania ).
