Description. ♂. Fully winged; body length 2.1–2.9 mm. Head black, except mandible testaceous; antenna brown, except scape and pedicel testaceous; mesosoma and metasoma black; legs brown, except tarsi and protibia testaceous. Antenna filiform, with antennomere 6 less than twice as long as broad (5:3.5); antennomeres in follow- ing proportions: 9:5:7:6:5:5:4.5:4:4:6.5. Head dull, completely reticulate rugose; frontal line complete; occipital carina complete; POL = 3; OL = 2.5; OOL = 6; OPL = 6; TL = 4. Mesoscutum, mesoscutellum and metanotum dull, reticulate rugose. Notauli complete, posteriorly separated; minimum distance between notauli longer than greatest breadth of lateral ocelli (6:2.5). In specimen from Madagascar, 25°00.40’S 46°18.20’E, notauli hardly visible. Metapectal-propodeal disc reticulate rugose, without transverse posterior keel; propodeal declivity reticulate rugose, without longitudinal keels (occasionally one or two tracks of longitudinal keels visible). In specimen from Madagascar, 21°13.22’S, 45°19.296’E, propodeal declivity with two tracks of longitudinal keels and median area shiny, unsculptured. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein as long as proximal part (10:10). Genitalia in Fig. 109E View FIGURE 109 .
