Description. ♀ ( Fig. 74E ). Fully winged; body length 2.4–3.4 mm. Completely testaceous-reddish, except petiole black, metanotum and metapectal-propodeal disc partly black, first segment of metasoma partly black (in two ♀♀ from South Africa, 34°27.41’S 19°21.39’E, metasoma completely testaceous). In specimen from South Africa, 33°56.232’S 18°57.711’E, BH12-FYN3-M05, head brown, except some testaceous spots on vertex; antenna testaceous, except antennomeres 1–3 brown; mesosoma and metasoma testaceous, except many brown spots; legs testaceous, except coxae, femora and tibiae partly brown.Antennomeres in following proportions: 10:5:6:5:5:5:5:5:4.5:6. Head dull, granulate; frontal line present; frons with two lateral keels near orbits and directed towards antennal toruli; occipital carina complete; POL = 4; OL = 5; OOL = 5 OPL = 5; TL = 5. Pronotum shiny, setose, slightly granulate; posterior surface much longer than anterior surface and slightly shorter than mesoscutum (10:11); pronotal tubercle reaching tegula. Mesoscutum shiny, granulate. Notauli incomplete, faintly and shortly visible near anterior margin of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc dull, with transverse posterior keel, reticulate rugose; propodeal declivity completely granulate, without longitudinal keels, not reticulate rugose. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (2.5:7). Protarsomeres in following proportions: 6:2:3:7:16. Enlarged claw ( Fig. 78D ) with proximal prominence bearing one long bristle. Protarsomere 5 ( Fig. 78D ) with two rows of 23–30 lamellae (30 in holotype); apex with four lamellae. Tibial spurs 1/1/2.

♂. Unknown.

Hosts. Unknown.

Distribution. South Africa.

Remarks. Anteon turneri is very similar to A. townesi Olmi 1984 ; the unique difference regards the forewing colouration ( A. townesi has two dark transverse bands; whereas A. turneri has completely hyaline wings). There is a possibility that these species are conspecific. They were both collected in the same locality (Walker Bay Nature Reserve). The discovery of the ♂♂ of both species should elucidate the species delimitation.
