Terminalia.
Male.
Segment 10. Incised deeply into pygofer, almost to base of pygofer, lateral margin convergent, sublinear, in dorsal view length/width=1.24–1.41 (n=5), compressed in lateral view ( Fig. 17A, B View FIGURE 17 ).
Pygofer. Much longer than wide in lateral view, anterior margin oblique, anterior apodeme large; basolateral suture right-angled, extending about half-way into pygofer lobe, region distad of basolateral suture with few (approximately 4) narrow macrosetae ( Fig. 17B View FIGURE 17 ); orientation of aedeagus in pygofer with shaft vertical in membranous recess in segment 10.
Pygofer lobe. Dorsal margin sublinear or convexly curvate, apex desclerotized, subapex sclerotized; process strongly concave; about 4 macrosetae near dorsomedial origin of pygofer process, 90–135 µm in length ( Fig. 15B View FIGURE 15 ), detail of apex of lobe laterally in Fig. 17I View FIGURE 17 and dorsally in Fig. 17J View FIGURE 17 with process curvate, orientation lateroposteriorly.
Subgenital plate. Greatest length/greatest width=1.22–1.35. Style reaching about half way into subgenital plate ( Fig. 17C View FIGURE 17 ).
Style. Greatest length/greatest width=4.02–4.26; length apophysis/greatest length=0.16–0.19; length base/ length greatest=0.35–0.38; angle of apophysis to sagittal plane 47–58° ( Fig. 17D View FIGURE 17 ).

Aedeagus. Paired, digitate teeth at base of anterior margin of shaft, curvate laterad ( Fig. 17E, G, H View FIGURE 17 ); apex about half as wide as medial width of shaft ( Fig. 17G View FIGURE 17 ); anterior margin apically and subapically finely denticulate ( Fig. 17F View FIGURE 17 ); posterior margin with single, median tooth and subbasal paired, close-set long teeth, about two times longer than median tooth. Gonopore ovoid, posteriorly between apex and subapex. Dorsal apodeme reduced. Preatrium elongate, slightly shorter than shaft, in line with aedeagal shaft; anterior margin at apex with lobulate process ( Fig. 17G View FIGURE 17 ).
Female.
Sternite 7. Isosceles trapezoid; distal width/basal width=0.67–0.74, greatest length/greatest width=0.47–0.49), lateral margins sublinear; posterior margin with wide notch, greatest median length/greatest lateral length=0.67– 0.74; angle of notch=127–143°. ( Figs 15O View FIGURE 15 , 18A View FIGURE 18 ).
Valvula 1. Parallel-sided, apex acute ( Fig. 18F View FIGURE 18 ); dorsal sculpture apically valvate, commonly elongate, acutely angled to margin ( Fig. 18K View FIGURE 18 ), sculpture strigate basally, parallel to margin ( Fig. 18L View FIGURE 18 ).
Valvula 2. Apex slightly wider than base, distal dorsal margin serrate ( Fig. 18G View FIGURE 18 ), with shallow, wide trough, with fine subserration, short, narrow rounded teeth, sculpture and serration at apex and subapex as in Figs 18I, 18J View FIGURE 18 respectively.
Valvula 3. Macrosetae number 15–20 at apex, two thirds to three quarter are 27–33 µm long, the rest are shorter setae, up to 25 µm ( Fig. 18H View FIGURE 18 ).
Valvifer 1. Length to width 1.35–1.57 (n=4) ( Fig. 18B View FIGURE 18 ), in dorsal view fused medially, as in Fig. 18C View FIGURE 18 .
Valvifer 2. Length to width 2.63–2.90 (n=4) ( Fig. 16D View FIGURE 16 ), 8–10 pore-like structures near base ( Fig. 18E View FIGURE 18 ).
Remarks. This new species is similar in size and coloration to that of the four species described by Stiller (1986), with the paired teeth at the base of the anterior margin of the male aedeagal shaft. The angle of the crown in males at 84–88°, females at 80–90°, is near that of P. koebergis (76–96°) and P. cedarbergensis (76–81°, male and female) and wider than in P piketensis (75–77°, males) and P. hawekwae (68–69°, males). For comparison, male genitalia of four species as in Stiller 1986 are included in Fig. 16 View FIGURE 16 : Aedeagus laterally, dorsally, connective and style, respectively for P. hawekwae ( Fig. 16A, F, K, P View FIGURE 16 ), P. cedarbergensis ( Fig. 16B, G, L, Q View FIGURE 16 ), P. piketensis ( Fig. 16C, H, M, R View FIGURE 16 ), P. koebergis ( Fig. 16D, I, N, S View FIGURE 16 ). The expanded apex of the aedeagus of P. cedarbergensis resembles the apex in C. bucapitatus .
