53. Anteon kivuanum (Benoit, 1951)

(Figs 54F, 56A, 57A)

Chelogynus kivuanus Benoit 1951c: 13 (♀; the ♂ described by Benoit (1951c: 15) has 2 longitudinal keels on propodeal decliv- ity (they are absent in the ♀), so that it was described as Anteon agile Olmi 1984).

In some specimens (from Kenya, South Africa and Uganda) vertex behind lateral ocelli with two oblique keels connecting lateral ocelli to occipital carina. Pronotum dull, granulate and punctate, with strong transverse keels; posterior surface shorter than mesoscutum (8:20). Mesoscutum shiny, very weakly granulate (strongly granulate in specimen from South Africa, 1.5 km E Mtunzini). Notauli incomplete, very reduced, shortly present near anterior margin of mesoscutum. Mesoscutellum shiny, unsculptured. Metanotum shiny, sculptured by longitudinal keels. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing with two dark transverse bands; distal part of 2r-rs&Rs vein shorter than proximal part (4:6). Protarsomeres in following proportions: 6:3:4:8:25. Enlarged claw (Fig. 57A) very long, longer than protarsomere 5, with proximal prominence bearing one long bristle. Protarsomere 5 (Fig. 57A) curvilinear, with basal part shorter than apical part, with two rows of about 10–12 lamellae; apex of protarsomere 5 with about 10–17 lamellae. Tibial spurs 1/1/2.

Head black, except mandible testaceous; antenna brown, except scape and pedicel testaceous; mesosoma and metasoma black; legs testaceous, except part of metacoxa and part of club of metafemur brown. Immature specimens completely brown. Antennomeres in following proportions: 10:4:4:4:4:4:4:4:4:5. Head shiny, granulate, with slight areolae; frontal line complete; in specimens from South Africa, 29°34.56’S 30°17.40’E, and Kenya, 3.30958°S 39.96538°E, head strongly granulate and reticulate rugose; frons with or without two lateral keels near orbits and directed towards antennal toruli; occipital carina complete; POL = 7; OL = 4; OOL = 5; OPL = 2.5; TL = 3. In large specimens, vertex with two oblique keels connecting lateral ocelli to occipital carina; small specimens without above oblique keels. Mesoscutum shiny, unsculptured or slightly granulate or punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.25–0.40 × length of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose; propodeal declivity without longitudinal keels, completely reticulate rugose (occasionally with left longitudinal keel). In two specimens from Madagascar, 12°15.46’S 49°23.51’E, propodeal declivity with two incomplete longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of 2r-rs& Rs vein much shorter than proximal part (3:7). Paramere (Fig. 54F) (figure 222 in Olmi 1984 erroneous) without distal inner pointed process and with small and broad proximal membranous process (Fig. 54F); in two specimens from South Africa, Graskop and 29°34.56’S 30°17.40’E, paramere with some transverse folds on their inner sides (Fig. 56A); in specimens from South Africa, Ashburton, 29°39’23’’S 30°27’41’’E, inner side of paramere with transverse folds or mosaic pattern. In specimens from South Africa, 32°32.033’S 25°14.267’’E, and Kenya, 3.30958°S 39.96538°E, paramere much shorter than penis. Tibial spurs 1/1/2.

Hosts. Cicadellidae (Guglielmino et al. 2013): in South Africa: Iassomorphus drakensteini (Naudé) .

Distribution. Central African Republic, Democratic Republic of the Congo, Kenya, Madagascar, South Africa, Uganda, Yemen.

Remarks. Anteon fiorii Olmi is very similar to A. kivuanum (Benoit) . The only difference is in respect of the colour: mostly black in kivuanum, mostly testaceous-reddish in fiorii . The only known male is that of A. kivuanum . Both species were collected in South Africa, Ashburton, by a temporally extensive survey using Malaise traps. The chelae of the two species are alike. The probability that the two species are conspecific is very high.
