Etymology . Named for the mountain range incorporating the type locality. Gender feminine. Description Male and female . Color . Tegmina . Ground colour tegmina greyish-white; all veins and some areas fuscous or with fuscous areas and yellowish veins. Teneral specimens lighter in colour ( Fig. 15G–I ). Claval area always with light to dark brown marks. Morphology Tegmina . Male, length/width=2.16–2.17; female, length/width=2.10–2.20. Hind wing .

Male, length tegmina/length hind wing=1.14–1.17; width tegmina/width hind wing=1.56–1.77; female, length tegmina/length hind wing=1.08–1.20; width tegmina/width hind wing=1.56–1.66. Measurements . Male (n=11). Apex of crown to apex of tegmina 3.03–3.17 mm ( Stiller 1986 , 3.00– 3.20 mm ); apex of crown to apex of abdomen 3.14–3.40 mm ( Stiller 1986 , 3.00– 3.48 mm ); crown length 0.67–0.74 mm ; crown length next to eyes 0.42–0.44 mm ; pronotum length 0.38–0.41 mm ; head width 1.13–1.17 mm ; pronotum width 1.02–1.07 mm ( Stiller 1986 , 0.89–1.12 mm ); ocellus diameter 28 µm; interocular distance 58–72 µm; crown angle 76–81°; crown length/crown length next to eye=1.55–1.72; head width/pronotum width=1.09–1.12; ocellus diameter/interocular distance=0.39–0.48; crown length/pronotum length=1.67–1.92; pronotum length/pronotum width=0.36–0.39. ( Stiller 1986 , interocular distance=width across disc of head, between medial margins of eyes 0.42–0.48 mm ). Female (n=7). Apex of crown to apex of tegmina 3.11–3.23 mm ( Stiller 1986 , 3.12–3.40 mm ); apex of crown to apex of abdomen 3.75–3.89 mm ( Stiller 1986 , 3.72–4.00 mm); crown length 0.72–0.74 mm ; crown length next to eyes 0.44–0.47 mm ; pronotum length 0.39–0.43 mm ; head width 1.16–1.24 mm ; pronotum width 1.05–1.13 mm ( Stiller 1986 , 1.04–1.10 mm ); ocellus diameter 28 µm; interocular distance 60–72 µm; crown angle 76–81°; crown length/crown length next to eye=1.57–1.66; head width/pronotum width=1.09–1.11; ocellus diameter/interocular distance=0.38–0.47; crown length/pronotum length=1.70–1.90; pronotum length/pronotum width=0.35–0.40. ( Stiller 1986 , interocular distance=width across disc of head, between medial margins of eyes 0.46–0.50 mm ). Terminalia Male . Segment 10 . Length/width=1.18–1.24. Pygofer lobe . Process strongly concave; 3–4, rarely 7 macrosetae, 59–119 µm in length. Subgenital plate . 1.16–1.42 times longer than wide. Style . Greatest length/greatest width=3.06–3.21; length apophysis/greatest length=0.19–0.23; length base/ length greatest=0.35–0.40; angle of apophysis to sagittal plane 49–62° ( Fig. 16Q ). Connective . Greatest width across arms/greatest width across stem=1.89–2.20; greatest length of arms/greatest length of stem=0.81–1.22; angle of arms 80–87°; greatest length/greatest width=0.67–0.72 ( Fig. 16L ). Aedeagus . Shaft of aedeagus relatively straight in lateral view with long slit-like apical gonopore, apex with flange-like lateral and terminal extensions; anterior margin with subapical teeth and pair of basal processes, posterior margin with pair of small, subapical teeth, development of all teeth shows some variation between individuals ( Fig. 16B, G ). Female . Sternite 7 . Posterior margin with wide notch, between posterolateral margins, curved or widely V-shaped; greatest length/greatest width=0.47–0.51; greatest median length/greatest lateral length=0.70–0.76, angle of notch 134–145°. 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 up to 14 longer setae near apex (27–35 µm), up to nine shorter setae (up to 25 µm). Valvifer 1 . Length/width=1.32–1.68 (n=4). Valvifer 2 . Length/width=2.40–2.64 (n=4); 6–8 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 paired, subapical teeth, apex of shaft expanded anteriad, posterior margin with short subapical paired teeth. Mapped in Fig. 32A by red circles.
