( Figs 35C , 38A )

Chelogynus kivuanus Benoit 1951c: 15 (♂: the ♂ described by Benoit (1951c: 15) has two longitudinal keels on propodeal declivity (they are absent in the ♀ of A. kivuanum ), so that it cannot be the opposite sex of A. kivuanum ; it was described afterwards as Anteon agile Olmi, 1984 ).

Anteon agile Olmi 1984: 354 ; Olmi et al. 2015: 340.

Description. ♀. Fully winged; body length 2.6–3.2 mm. Head black, except mandible testaceous; antenna brown, except scape and pedicel testaceous; mesosoma black, except pronotum reddish or brown; metasoma black; legs testaceous, except metacoxa occasionally partly brown. Antenna filiform; antennomeres in following proportions: 10:6:9:10:8:8:8:8:8:11. Head shiny, smooth, slightly punctate, unsculptured among punctures, more strongly punctate behind ocelli; frontal line absent; frons with no lateral keels; occipital carina complete; POL = 5; OL = 5; OOL = 6; OPL = 5; TL = 7. Pronotum shiny, smooth, almost flat, finely punctate, unsculptured among punctures, with pos- terior surface longer than mesoscutum (14:11); pronotal tubercle reaching tegula. Mesoscutum shiny, smooth, finely punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.65 × length of mesoscutum. Mesoscutellum and metanotum shiny, smooth, slightly punctate, unsculptured among punctures. Metapectal-propodeal disc reticulate rugose, with strong transverse posterior keel; propodeal declivity with two longitudinal keels and median area as rugose as lateral areas. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (3:6). Protarsomeres in following proportions: 9:3:3.5:12:21; protarsomere 4 much longer than basal part of 5 (12:8). Enlarged claw ( Fig. 35C ) with proximal prominence bearing one long bristle. Protarsomere 5 ( Fig. 35C ) with basal part shorter than distal part (8:13), with two rows of 28 lamellae; apex with 4 lamellae. Tibial spurs 1/1/2.

♂. Fully winged; body length 1.7–2.7 mm. Head black, except mandible testaceous; antenna brown; occasion- ally antennomere 1 testaceous; mesosoma and metasoma black; tegula testaceous; legs testaceous, except metacoxa proximally darkened. Antenna filiform; antennomeres in following proportions: 12:6:10:10:10:10:8:9:10:10. Head shiny, strongly punctate, unsculptured among punctures; frontal line absent; frons without lateral keels along orbits directed towards antennal toruli; occipital carina complete; POL = 5; OL = 3; OOL = 7; OPL = 3; TL = 5; ocellar triangle with slight keels joining ocelli. Mesoscutum, mesoscutellum and metanotum shiny, smooth, strongly punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.65 × length of mesoscutum. Metapectal-propodeal disc reticulate rugose, with strong transverse posterior keel; propodeal declivity with two longitudinal keels and median area approximately as rugose as lateral areas. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (4:12). Paramere ( Fig. 38A ) with distal inner pointed process and proximal membranous process. Tibial spurs 1/1/2.
