Hind wing. Male, length/width=3.24–3.36; female, length/width=3.23.
Tegmina-hind wing relation. Male, length tegmina/length hind wing=1.15; width tegmina/width hind wing=1.76–1.99; female, length tegmina/length hind wing=1.13; width tegmina/width hind wing=1.77.
Measurements.
Male (n=10). Apex of crown to apex of tegmina 3.02–3.19 mm; apex of crown to apex of abdomen 3.07–3.44 mm; crown length 0.70–0.73 mm; crown length next to eyes 0.42–0.45 mm; pronotum length 0.38–0.41 mm; head width 1.11–1.17 mm; pronotum width 1.02–1.09 mm; ocellus diameter 25–29 µm; interocular distance 68–77 µm; crown angle 73–98°; crown length/crown length next to eye=1.59–1.70; head width/pronotum width=1.06–1.10; ocellus diameter/interocular distance=0.34–0.41; crown length/pronotum length=1.73–1.88; pronotum length/ pronotum width=0.36–0.39. ( Stiller 1986, interocular distance=width across disc of head, between medial margins of eyes 0.42–0.46 mm).
Female (n=6). Apex of crown to apex of tegmina 3.04–3.23 mm (in Stiller, 1986, 3.08–3.84 mm); apex of crown to apex of abdomen 3.63–4.01 mm (in Stiller, 1986, 3.24–3.92 mm); crown length 0.71–0.76 mm (in Stiller, 1986, 0.72–0.74 mm); crown length next to eyes 0.43–0.47 mm (in Stiller, 1986, 0.45–0.46 mm); pronotum length 0.39–0.41 mm (in Stiller, 1986, 0.39–0.40 mm); head width 1.14–1.20 mm (in Stiller, 1986, 1.13–1.15 mm); pronotum width 1.06–1.11 mm (in Stiller, 1986, 1.04–1.06 mm); ocellus diameter 22–29 µm; interocular distance 63–75 µm in Stiller, 1986, 0.44–0.46 mm); crown angle 75–79°; crown length/crown length next to eye=1.61–1.67; head width/pronotum width=1.07–1.09; ocellus diameter/interocular distance=0.30–0.45; crown length/pronotum length=1.75–1.93; pronotum length/pronotum width=0.36–0.37. ( Stiller 1986, interocular distance incorrect for width across disc of head, between medial margins of eyes 0.42–0.46 mm).
Terminalia.
Male.
Segment 10. Length/width=1.11–1.24.
Pygofer lobe. Process strongly concave; 3–5 macrosetae.
Subgenital plate. Subgenital plate 1.19–1.38 times longer than wide.
Style. Greatest length/greatest width=4.00–4.64; length apophysis/greatest length=0.17–0.20; length base/ length greatest=0.35–0.39; angle of apophysis to sagittal plane 46–72° ( Fig. 14R View FIGURE 14 ).
Connective. Greatest width across arms/greatest width across stem=1.77–2.09; greatest length of arms/greatest length of stem=1.05–1.27; angle of arms 78–84°; greatest length/greatest width=0.71–0.74 ( Fig. 14M View FIGURE 14 ).
Aedeagus. Shaft sublinear in lateral view, gonopore apical, rounded, anterior margin (dorsal in Stiller 1986) with subapical paired elongate teeth (about as long as width of shaft at point of attachment), posterior margin (ventral in Stiller 1986) with paired, apical short teeth; development of teeth variable ( Fig. 14C, H View FIGURE 14 ).
Female.
Sternite 7. V-shaped to arched incision ( Fig. 13O View FIGURE 13 ). Greatest length/greatest width=0.48; greatest median length/ greatest lateral length=0.73, angle of notch 138°.
Valvula 1. Parallel-sided, apex acute, sculpture as in P. postspina sp. n.
Valvula 2. Serrate in distal half, slightly wider than base.
Valvula 3. Margin and submargin with 25–26 setae near apex (about 15 long setae 28–37 µm, about five shorter setae up to 25 µm).
Valvifer 1. Length/width=1.48–1.59 (n=1).
Valvifer 2. Length/width=2.58–2.74 (n=1); 8–9 pore-like structures.
Remarks. The combination of features of acute crown, marking of the dorsum of the head, size and specifically the aedeagus distinguish this species. The anterior margin of the aedeagal shaft with subapical, elongate, paired teeth, apex of shaft as wide as median width, posterior margin with short, apical, paired teeth.
