(BRPR28: BIOTA-FAPESP) ( ZMBN ) . Diagnostic characters. The species differ from P. forcipata by having a bilobed gonostylus with lateral lobe adpressed to gonostylus, median volsella subrectangular and superior volsella with 2–4 large tubercles with apical seta in basal half.

Hypopygium ( Figs 146–147 ). Anal point 12–18 µm long, 7–8 µm wide at base, with 0–4 setae. Tergite IX with 11–15 additional setae. Laterosternite IX with 2–5 setae. Phallapodeme 70–78 µm long, apodeme lobe with 2 indistinct wrinkles. Sternapodeme evenly rounded with no trace of oral projections, arched part about 45–50 µm long. Virga apparently with 2 tapering spines, 11–16 µm long. Gonocoxite 107–146 µm long. Superior volsella 28–32 µm long, sigmoid, tapering, apex projecting anteriomedially, with anterior fringe of long microtrichia in apical half and 2–4 conspicuous large tubercles with apical seta in basal half. Median volsella subrectangular with rounded apex, 11–15 µm wide at base, 21–25 µm long, covered with microtrichia and with anterior and apical fringe of long microtrichia. Inferior volsella with 6–7 µm wide, 12–15 µm long anterior lobe, with rounded to weakly bilobed apex, with few apical setae; median lobe 10–14 µm wide, 17– 18 µm long, dorsally covered with orally curved microtrichia. Gonostylus 44–56 µm long, narrow; with 30– 38 µm long lateral lobe partly fused with gonostylus, with long medially directed microtrichia; megaseta 9–11 µm long. HR 2.41–2.60. HV 2.85–3.25. Distribution and biology. The species was taken in two nature reserves with Mata Atlântica forest in São Paulo and Paraná States at altitudes above 800 m a.s.l. In São Paulo it was collected in a light trap (CDC) while in Paraná in Malaise traps.
