( Figs 16A–F ) Diagnosis: Eyes touching for distance equal to 1.5–2 times ocellar triangle. This species can be recognised by the edge of S7 being visible in dorsal view; the gonopods having minute hairs on median edges and by the phallic guide having two lateral projections in ventral view and the tip of the PG forming a hook in lateral view.

[these specimens were examined after the types has been selected, and labelled, therefore they are not part of the type series] Male Head . Third antennal segment short acuminate; brown, distal half yellowish. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose; eyes touching for distance equal to 1.5–2 times ocellar triangle. Occiput completely silvery pollinose. Thorax . Humeri pale brown. Mesonotum (viewed obliquely from front) brownish pollinose, along anterior margin somewhat more silvery; also silvery from the side. Scutellum subshining black, with 5–6 pairs of minute hairs. Dorsocentral hairs present. Halter yellow, base darker. FIGURE 16. Male genitalia of Eudorylas brandbergensis sp. nov. (A–F) and E. conformis (G–K).—A: outer surstylus with phallic guide and outer gonopod, lateral view, B: dorsal view, C: inner surstylus, lateral view, D: surstyli, dorsal view, E: sperm pump with ejaculatory apodeme, F: ventral view with phallic guide and phallus (without ST8), G: outer surstylus with phallic guide, phallus and outer gonopod, lateral view, H: surstyli (damaged), dorsal view, I: inner surstylus, lateral view, J: dorsal view, K: ventral view with phallic guide, phallus, sperm pump and ejaculatory apodeme (without ST8). Scale bars: 0.1 mm Legs. Trochanters and femora dark brown (f3 shining pv), knees and basal half of tibiae yellow, tibiae otherwise brow. Tarsal segments yellow-brown, last segment brown. Ventroapical row of 3–6 short, dark spines on first four femora; 4–5 longer spines on 3rd femur (as long as width of t3 at base). Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. Hind trochanter without hairs or spines on ventral side. Pulvilli slightly shorter than last tarsal segment. Wing. Fourth costal section 0.8–0.9 times as long as third costal section. Cross-vein R-M before 1/3, almost at 1/4 of discal cell. Pterostigma coloured on distal 4/5. Hairs on tegula missing. Abdomen . Viewed obliquely from front tergites slightly pollinose, also on hind margins and on the sides. Hairs dispersed, short, pale and weakly developed. Laterally 2–4 dark spines on first tergite. Postabdomen in dorsal view: edge of S7 visible; T5 1.1–1.2 times as long as ST8. Genitalia without dissection: ST8 rectangular in dorsal view, m.a. triangle shaped, facing pv, EP and SS black. Genitalia. Surstyli symmetrical, inner edges pointing towards each other; ST8 broad, m.a. as wide as half the width of ST8 ( Fig. 16B ). Borders of SES uncertain; gonopods symmetrical, with minute hairs along median edges; hypandrium with broad lobes; phallic guide broad, with projections on each side in ventral view ( Fig. 16F ), hook shaped in lateral view ( Fig. 16A ); phallus trifid, with teeth along two branches; ejaculatory apodeme mushroom shaped; sperm pump elongated, flat ( Fig. 16E ). Female (NMSA specimen—no head) As male except for the following characters. Pulvilli and claws about 1.5 times as long as last tarsal segment. Female ovipositor with modified S6 to receive piercer. Distribution— Namibia , South Africa , Zimbabwe . Etymology —The name was derived from the type locality, Brandberg.
