60. Anteon malagasy Olmi, Copeland & van Noort, sp. nov.

( 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 ).
