Diagnosis. ♀: fully winged ( Figs 31D, E ); rarely brachypterous (Figs 41A, B); occipital carina complete; palpal formula 6/3; antenna without ADOs; forewing with three cells enclosed by pigmented veins (C, R and 1Cu) ( Figs 31D, E ); forewing with 2r-rs&Rs vein and pterostigma ( Figs 31D, E ); distal part of 2r-rs&Rs vein much shorter than proximal part ( Figs 31D, E ), occasionally slightly shorter, as long as, or longer than proximal part; metapectal-propodeal disc usually with transverse posterior keel ( Fig. 34A ); protarsus chelate ( Figs 31D, E ); inner side of enlarged claw with proximal prominence bearing one long bristle ( Fig. 33C ); tibial spurs 1/1/2. ♂: fully winged ( Figs 32A, B ); rarely brachypterous; occipital carina complete; vertex of head usually without two oblique keels connecting lateral ocelli to occipital carina; palpal formula 6/3; forewing with three cells enclosed by pigmented veins (C, R and 1Cu) ( Figs 32A, B ); forewing with 2r-rs&Rs vein and pterostigma ( Figs 32A, B ); distal part of 2r-rs&Rs vein much shorter than proximal part ( Figs 32A, B ), occasionally slightly shorter, as long as, or longer than proximal part; pterostigma less than 4 × as long as broad ( Figs 32A, B ); metapectal-propodeal disc usually with transverse posterior keel ( Fig. 34C ); paramere without large inner branch wrapping penis ( Fig. 35F ); tibial spurs 1/1/2.

Distribution. Worldwide.

Hosts. Cicadellidae ( Guglielmino & Olmi 1997, 2006, 2007; Guglielmino et al. 2013) ( Figs 32 C-E).

World species. 464 species are known, 106 in the Afrotropical region.

Remarks. Larvae of Anteon were described by Ponomarenko (1975b) and more recently by Guglielmino et al. (2017a). Leafhoppers parasitized by Anteon species usually show dryinid sacs situated in a latero-ventral position between the prothorax and the mesothorax ( Fig. 32C ), rarely positioned on the ventral side.
