description: Proekoides hawekwae Stiller, 1986
(Figs 15J, 16A, F, K, P, 27C)
Type material, holotype not examined.
Type locality. Holotype male, South Africa, Western Cape province, Du Toits Kloof Pass, between Paarl and Worcester; -33.71, 19.06; 23 Jan. 1985; J.G. Theron leg.
Paratypes. 3♂♂
South Africa, Western Cape province: 3♂♂; Du Toits Kloof Pass; -33.71, 19.06; 23 Jan. 1985; J.G. Theron leg.; CCDL28237; SANC.
Diagnosis. Aedeagal shaft with anterior margin with small, paired subapical teeth, posterior margin with small, paired medial teeth, shaft apex about as wide as mid-section of shaft; preatrium about as long as shaft.
Etymology. Named for the mountain where the specimens were collected. Gender feminine.
Description.
Male and female.
Color. Ground color of head and pronotum ochraceous, median line reddish-brown, extended into pronotum. Ground colour of tegmina greyish-white with some areas and most veins dark brown; light brown area present in claval region and sometimes brown spot in inner anteapical cell (Fig. 13J).
Morphology.
Tegmina. Length/width=1.98–2.02.
Hind wing. Length/width=3.13–3.45.
Tegmina hind wing relation. Length tegmina/length hind wing=1.13–1.14; width tegmina/width hind wing=1.79–1.95.
Measurements.
Male (n=3). Apex of crown to apex of tegmina 3.30–3.53 mm (Stiller 1986, 3.04–3.52 mm); crown length 0.88–0.92 mm (Stiller 1986, 3.44–3.68 mm); crown length next to eyes 0.45–0.48 mm; pronotum length 0.39–0.42 mm; head width 1.20–1.25 mm; pronotum width 1.13 mm (Stiller 1986, 1.04–1.06 mm); ocellus diameter 28 µm; interocular distance 84 µm; crown angle 68–69°; crown length/crown length next to eye=1.85–2.02; head width/ pronotum width=1.06–1.10; ocellus diameter/interocular distance=0.33; crown length/pronotum length=2.10–2.34; pronotum length/pronotum width=0.35–0.37. (Stiller 1986, interocular distance=width across disc of head, between medial margins of eyes 0.44–0.50 mm).
Female. No specimens examined. Measurements in Stiller (1986), apex of crown to apex of tegmina 3.12–3.60 mm; apex of crown to apex of abdomen 3.64–4.60 mm, interocular distance 0.44–0.54 mm, pronotum width 1.10– 1.20 mm.
Terminalia.
Male.
Segment 10. Length/width=0.99.
Pygofer lobe. Process weakly concave; 3–5 macrosetae, 101–147 µm in length.
Subgenital plate. Subgenital plate 1.43–1.61 times longer than wide.
Style. Greatest length/greatest width=4.22–5.10; length apophysis/greatest length=0.17–0.24; length base/ length greatest=0.34–0.39; angle of apophysis to sagittal plane 48–59° (Fig. 14P).
Connective. Greatest width across arms/greatest width across stem=1.89–2.11; greatest length of arms/greatest length of stem=1.59–1.78; angle of arms 89–91°; greatest length/greatest width=0.56–0.59 (Fig. 14K).
Aedeagus. Shaft slightly curved in lateral view with triangular gonopore, wide at anterior margin, narrow at posterior margin; anterior margin (dorsal margin in Stiller, 1986) with pair of subapical teeth and pair of basal processes; posterior margin (ventral) with pair of small teeth at mid-length (Fig. 14A, F); development of teeth shows some variation between individuals.
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 paired teeth, apex of shaft as wide as median width (not expanded anteriad as in P. cedarbergensis), posterior margin with short, median, paired teeth. In P. koebergis the posterior margin of the aedeagal shaft has similar median paired teeth, but the anterior margin has apical paired teeth.
