( Figs 58B , 60 C–E, 62 )

Diagnosis. ♂ of Anteon with head completely strongly reticulate rugose ( Fig. 58B ); propodeal declivity reticulate rugose, with one or two longitudinal keels, with median area rugose; paramere with proximal inner lobe provided or not with mosaic sculpture ( Figs 60C, D ).

Description. ♂ ( Figs 58B , 62 ). Fully winged; body length 2.1–2.2 mm. Head black, except mandible testaceous; antenna testaceous (in paratype brown); mesosoma black; metasoma brown; legs testaceous (in paratype metacoxa and club of metafemur partly brown). Antenna filiform; antennomeres in following proportions: 9:5:5:5:5:5:5:5:5:7. Head ( Fig. 62D ) dull, completely strongly granulate and reticulate rugose; frontal line complete; frons without lateral keels near orbits directed towards antennal toruli; occipital carina complete; POL = 7; OL = 3; OOL = 5; OPL = 2; TL = 3; greatest breadth of lateral ocelli about as long as OPL. Mesoscutum shiny, completely slightly granulate. In specimen from Madagascar, 21°13.57’S 47°22.19’E, MA-02-09A-06, mesoscutum punctate, unsculptured among punctures. Notauli ( Fig. 62B ) incomplete, reaching about 0.3–0.4 × length of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc ( Fig. 62B ) with strong transverse posterior keel, reticulate rugose, dull; propodeal declivity dull, reticulate rugose, with one or two longitudinal keels; areolae of propodeal declivity about as large as those of metapectal-propodeal disc. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (2:7). Paramere ( Figs 60 C-E) without distal in- ner pointed process, with inner more or less large proximal lobe not covered with papillae and having ( Fig. 60C ) or not having ( Figs 60D, E ) a mosaic pattern. Tibial spurs 1/1/2.

Hosts. Unknown.

Distribution. Madagascar.

Etymology. The species is named malagasy after the collection site in Madagascar.

Remarks. Anteon malagasy is similar to A. kwazuluense Olmi, 2007 , but the propodeal declivity has areolae as large as those of the metapectal-propodeal disc (the areolae are less wide than those of the metapectal-propodeal disc in A. kwazuluense ). Anteon malagasy is also similar to A. madagascolum ( Benoit, 1954) , but the shape of the inner process of the paramere is different ( Figs 56E, F ).
