description: Eudorylas amuscarium (Hardy, 1959)
(Figs 14A–F, 39L)
Dorilas (Eudorylas) amuscarium Hardy 1959 a: 398.
Diagnosis: One erect anteromedial hair on 3rd tibia. S5 and S4 divided. Surstyli elongated, both C-shaped in lateral view (because of the process at base); cerci asymmetrically placed, small; phallic guide with two lobes and an unusual structure in the middle of the space between the SS, connected to the base of the lobes on PG.

Male
Head. Third antennal segment acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black, lower part silvery pollinose, except narrow black line dorsally; eyes touching for distance equal to 3 times ocellar triangle. Occiput silvery pollinose.
Thorax. Humeri pale brown (yellow). Mesonotum (viewed obliquely from front) subshining black, anterior part silvery pollinose; also silvery from the side. Scutellum brownish pollinose, 8–9 pairs of pale hairs. Dorsocentral hairs weakly developed. Halter, knob dark brown, stem pale.
Legs. Trochanters and base of femora yellow, femora dark brown, shining posteriorly, knees, tibiae, tarsal segments yellow, last segment brown. Ventroapical row of 3–4 spines on f1, 10–14 very short, black spines on f2; no spines on 3rd femur. Subapical (distal) spines on first four tibiae present. One erect anteromedial hair on 3rd tibia. Hind trochanter with 2–3 white hairs on ventral side. Pulvilli as long as last tarsal segment.
Wing. Fourth costal section 0.8 times as long as third costal section. Cross-vein R-M at 2/5 of discal cell. Pterostigma fully coloured. Hairs on tegula missing.
Abdomen. Viewed obliquely from front tergites brownish pollinose, hind margins silvery grey, sides completely silvery. Hairs dispersed, very short and weakly developed. Lateral spines on first tergite: 5–6, dark brown. Postabdomen in dorsal view: T6, S7 visible; T5 as long as ST8. Genitalia without dissection: ST8 large, mainly yellow, m.a. small, EP+SS yellow, SS look large in size.
Genitalia. S5 and S4 divided. Surstyli elongated, both C-shaped in lateral view (because of the process at base); epandrium short and wide, cerci asymmetrically placed, small; ST8 with round m.a. (Fig. 14B). SES uncertain; gonopods weakly developed or absent (see remarks), IG as a rounded protuberance; phallic guide with two lobes and a special structure in the middle of the space between the SS, connected to the base of the lobes on PG (Fig. 14E); phallus trifid, short; ejaculatory apodeme broadening at tip, otherwise flat; sperm pump elongated, linear with two membranous lobes (Fig. 14D).
Female
As male except for the following characters. Frons, eyes separated; completely silver-grey pollinose until 1/6–1/4 from the antennae and along margins up to half of the frons. Enlarged ommatidia silvery shining. Pulvilli and claws about 1.5–2 times as long as last tarsal segment. Female ovipositor (Fig. 39L) straight.
Remarks —The presence of gonopods remains uncertain due to the presence of an additional structure protruding from the dorsal side of the PG that hampers unequivocal interpretation.
Distribution— South Africa.
