Redescription. FEMALE (paratype and non-type specimens). Body length about 1120 µm (dry-mounted specimens from Italy). Head mostly brown, with some yellow; scape mostly light brown, pedicel mostly brown, and flagellum dark brown; pronotum yellow to brown, mesoscutum mostly brown to dark brown anteriorly and light brown posteriorly, scutellum and axillae light brown to brown, dorsellum and propodeum brown to dark brown; legs mostly light brown; gaster mostly yellow except light brown to brown apically.

Antenna ( Figs 58, 60 , 61 ) with radicle about 0.3 × total length of scape, rest of scape 3.1–3.6 × as long as wide; pedicel longer than F 1; F 1 the shortest funicle segment, F 3 about as long as F 4 or slightly longer, F 5 –F 7 more or less subequal in length, F 8 a little shorter and broader, with an incision at apex; mps on F 4 (usually 0 or, occasionally, 1), F 5 (usually 1 except 2 in the specimens from Mongolia), F 6 (2), F 7 (2) and F 8 (2); clava with 8 mps, 3.5–3.8 × as long as wide, almost as long as combined length of F 6 –F 8.

Mesosoma ( Figs 60 , 63 ). Propodeum ( Fig. 62 ) with submedian lines wide apart. Fore wing ( Figs 59, 60 , 64 ) 3.1–3.4 × as long as wide; longest marginal seta 0.2–0.3 × maximum wing width. Fore wing disc almost hyaline, bare behind submarginal vein, setose behind and beyond marginal vein. Hind wing 19–20 × as long as wide; disc almost hyaline, setose; longest marginal seta 2.4–2.6 × maximum wing width.

Metasoma ( Figs 60 , 63 ) longer than mesosoma. Petiole about 2 × as wide as long. Ovipositor occupying 0.7–0.8 × length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 1.1–1.3: 1.

MALE. Unknown.

Diagnosis. Gonatocerus africanus is characterized by the distinctive yellow-brown body color and the female antenna ( Figs 58 , 61 ) with F 3 and F 4 subequal in length and bearing usually 1 mps on F 5 and 2 mps on F 6 –F 8.

Hosts. Unknown.
