Anteon sakalavense Olmi, Copeland & van Noort , sp. nov. ( Figs 70A , 72B , 73 ) Diagnosis . Macropterous of Anteon with propodeal declivity with two incomplete longitudinal keels, reaching about 0.5 × length of propodeal declivity; protarsomere 4 longer than basal part of 5; protarsomere 5 ( Fig. 70A ) with inner side curvilinear, with distal region distinct from median and proximal regions, with basal part much shorter than apical part. Description . ( Figs 72B , 73 ). Fully winged; body length 2.3 mm . Head ferruginous-dark; antenna testaceous; mesosoma ferruginous-dark, except metapectal-propodeal disc black; petiole black; metasoma brown-testaceous; legs testaceous. Antenna clavate; antennomeres in following proportions: 11:6:8:5:4:5:5:5:5:7. Head ( Fig. 73C ) dull, sculptured by many slightly irregular keels; frontal line complete; frons with two slight lateral keels near orbits directed towards antennal toruli; occipital carina complete; POL = 4; OL = 4; OOL = 3; OPL = 4; TL = 6; greatest breadth of lateral ocelli shorter than OPL (2.5:4). Pronotum flat, shiny, sculptured by many very slight transverse striae, with anterior surface very short, shorter than posterior surface (2:11); posterior surface shorter than mesoscutum (11:14), with anterior and lateral margins sharp; pronotal tubercle reaching tegula. Mesoscutum, mesoscutellum and metanotum shiny, unsculptured ( Fig. 73A ). Notauli incomplete, reaching approximately 0.6 × length of mesoscutum. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose; propodeal declivity reticulate rugose, with two incomplete longitudinal keels reaching about 0.5 × length of propodeal declivity. Forewing ( Fig. 73D ) with one small dark spot around 2r-rs&Rs vein; distal part of 2r-rs&Rs vein shorter than proximal part (4.5:9). Protarsomeres in following proportions: 6:2:4:9:18. Protarsomere 2 produced into hook. Protarsomere 4 longer than basal part of 5. Enlarged claw ( Fig. 70A ) with proximal prominence bearing one long bristle. Protarsomere 5 ( Fig. 70A ) with inner side curvilinear, with distal region distinct from median and proximal regions, with basal part much shorter than apical part, with one row of 33 lamellae; apex with about 9 lamellae. Tibial spurs 1/1/2. . Unknown. Material examined .
