Distribution. Worldwide.

Hosts. Cicadellidae ( Guglielmino & Olmi 1997, 2006, 2007; Guglielmino et al. 2013) ( Figs 32 View FIGURE 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 View FIGURE 32 ), rarely positioned on the ventral side.
