( Fig. 67B )

Diagnosis. Macropterous ♀ of Anteon with colour mostly black; head granulate, with slight irregular striae and areolae; pronotum with posterior surface much shorter than mesoscutum; mesoscutum granulate; forewing hyaline, without dark transverse bands; propodeal declivity rugose, without longitudinal keels; protarsomere 4 at most 0.5 × as long as basal part of 5; protarsomere 5 with basal part much longer than distal part ( Fig. 67B ).

Description. ♀. Fully winged; body length 2.1 mm. Head black, except mandible testaceous; antenna brown, except scape and pedicel testaceous; mesosoma black; metasoma brown; legs brown-testaceous. Antenna clavate; antennomeres in following proportions: 10:4:4:4:4:5:4:4:5:6. Head dull, granulate, with slight irregular striae and areolae; frontal line absent; frons without lateral keels near orbits directed towards antennal toruli; occipital carina complete; POL = 7; OL = 3; OOL = 4; OPL = 5; TL = 4; greatest breadth of posterior ocellus shorter than OPL (1:5). Pronotum dull, transversely striate, except posterior surface almost completely unsculptured; posterior surface very short, shorter than anterior surface and shorter than mesoscutum (3:12); pronotal tubercle reaching tegula. Mesoscutum dull, granulate. Notauli incomplete, shortly visible near anterior margin of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (2:7). Protarsomeres in following proportions: 9:1:2:2:6. Enlarged claw ( Fig. 67B ) with proximal prominence bearing one long bristle.
