MADAGASCAR • 1 ♂ (on slide); same locality data as for holotype; “MADAGASCAR: Antsiranana Prov. Fôret de Binara , 650–800 m 9.1 km 233° SW of Daraina 13°15′48″S, 49°36′12″E 3.xii.2003, B. Fisher, YPT rainfor.[est] BLF9657, CAS LOT # 014721 View Materials ”; CAS GoogleMaps .
COLOR. Head and rest of body ( Fig. 9C View Fig ) mostly whitish to very light brown with brownish suffusions on vertex, mesoscutum, and middle of scutellum, except trabeculae dark brown and mesopleuron with brown spot at lower margin; scape and F1 whitish, pedicel light brown, F2–F6 brown, clava white; legs whitish.
HEAD ( Fig. 8B, E View Fig ). Large, 1.3 × as wide as mesosoma; face smooth, with fine, inconspicuous setae below toruli; toruli raised a little above face surface and slightly projecting forward, rest of head strongly reticulate; vertex with several pairs of short setae.
ANTENNA ( Fig. 8D View Fig ). Scape 2.6× as long as wide excluding radicle; pedicel smooth, longer than F1 and 1.7× as long as wide; F5 as long as F6, length to width ratios of funiculars: F1 = 2.2, F2 = 5.3; F3 = 3.8; F4 = 2.6; F5 = 1.9; F6 = 1.5; clava 3.0× as long as wide, almost as long as combined length of 4 preceding flagellomeres.
MESOSOMA ( Fig. 8B–C, E View Fig ). Smooth, about 1.9 × as long as wide; pronotum, mesoscutum except along anterior margin, scutellum, frenum, and metanotum with reticulate sculpture; pronotum large, with 3 pairs of weak setae at posterior margin; axillar seta 0.024 mm long; scutellum + frenum longer than mesoscutum, scutellum not divided mediolongitudinally; propodeum ( Fig. 8C View Fig ) with prominent, widely separated submedian carinae extending almost to anterior margin.
WINGS. Brachypterous. Fore wing ( Fig. 9A View Fig ) with pointed apex, 3.6× as long as wide, extending a little beyond apex of gaster ( Fig. 9C View Fig ); marginal vein with 1 dorsal macrochaeta; disc infumate and with 2 brown bands, densely setose beyond venation, with the modified, very short and strong, discal setae originating behind apex of submarginal vein, with numerous round ‘cells’ beyond venation; longest marginal seta 0.15 × greatest width of wing, proximal fringe setae on anterior margin much thicker than other fringe setae. Hind wing ( Fig. 9B View Fig ) strongly reduced, almost without membrane and setae.
LEGS. All legs smooth, metacoxa with sparse white setae. METASOMA. Petiole ( Fig. 8C View Fig ) smooth, 2.5× as long as wide and slightly swollen medially, a little longer than metacoxa. Ovipositor 0.85 × length of gaster ( Fig. 8E View Fig ), barely exserted beyond its apex, 1.4 × length of mesotibia and about 1.1 × length of metatibia.
MEASUREMENTS (µm). Body (critical point dried specimen prior to slide-mounting) = 925; head (critical point dried specimen prior to slide-mounting) = 170; mesosoma = 364; mesoscutum = 103; scutellum = 121; petiole = 91; gaster = 382; ovipositor = 342. Radicle = 13; rest of scape = 149; pedicel = 58; F1 = 33; F2 = 97; F3 = 70; F4 = 55; F5 = 44; F6 = 44; clava = 203. Fore wing = 588:165; venation = 203; longest marginal seta = 24. Hind wing = 227:9. Mesotibia = 248; metatibia = 324.
MEASUREMENTS. Body length (of the critical point dried specimen prior to slide-mounting) 1.125 mm, head length (of the critical point dried specimen prior to slide-mounting) 0.165 mm.
COLOR. Head mostly brown except face and occiput light brown and trabeculae dark brown; pronotum yellowish dorsally and pale laterally, remainder of mesosoma brown; petiole whitish, gaster mostly whitish basally and brownish laterally and apically; scape and pedicel pale light brown, flagellum brown except F9–F11 white (F9 less so than following flagellomeres); legs mostly whitish to pale light brown except pro- and mesocoxae partially and metacoxa entirely white.
MESOSOMA. Vertex smooth. Mesosoma smooth except mesoscutum partially with mesh-like longitudinal sculpture; pronotum not enlarged, much shorter than in female; scutellum almost completely (except posteriorly) divided mediolongitudinally by a narrow groove; propodeum ( Figs 10B View Fig , 11C View Fig ) with submedian carinae as in female.
WINGS. Macropterous; fore wing ( Fig. 12A View Fig ) 1.206 mm long, 4.9× as long as wide, marginal vein with 2 dorsal macrochaetae, disc without round ‘cells’, with 3 or 4 setae behind apex of submarginal vein, bare just beyond venation and densely setose elsewhere, discal microtrichia normal, long, longest marginal seta a little more than 0.9× greatest width of wing; hind wing ( Fig. 12A View Fig ) about 32 × as long as wide, with membrane narrow, its longest marginal seta 5.5 × greatest width of wing.
METASOMA. Petiole dorsally with a few inconspicuous cross-ridges.
ANTENNA ( Fig. 11A View Fig ). 2.155 mm long, with scape smooth, 2.5 × as long as wide excluding radicle, and much shorter than any funicular; all funiculars subequal in length except F6 and F7 slightly shorter.
