Material examined.

Holotype female (CNC) in Canada balsam on slide (Fig. 5 ) labelled: 1. " Chile: Cautin , 1150m, Conguillio Nat. Park, Auraucaria Nothofagus Feb. 6.1988 18PT L. Masner Chile Exp. " 2. " Neopolynemoidea chilensis f# Huber HOLOTYPE " . Paratypes: one female (CNC) on card, with same locality data as holotype .

Diagnosis.

Neopolynemoidea chilensis is the only described species in the genus so its diagnosis the same as for the generic description.

Description.

Female. Colour. Uniformly brown; scape, pedicel and legs except coxae and metafemur brownish yellow. Fore wing with brown suffusion except for a small clear area distal to stigma, a larger triangular area along posterior margin, a clear area anterior to retinaculum and a small one posterior to parastigma (Fig. 7 ). Body length. 1000 (paratype, card mount). Head. Head width ~226. Face with 6 setae ventral to level of ventral margin of torulus and faint engraved reticulations except for a band of more distinct striations extending between eyes ventral to toruli and a narrow dorsal band extending along preorbital groove (Fig. 2a ). Vertex with 2 setae between lateral ocelli and slightly more distinct engraved reticulations. Back of head with faint transverse engraved reticulations dorsally, becoming vertical lateral to foramen, 2 short seta dorsal to foramen, and a few shorter setae laterally along eye (Fig. 2b ). Antenna. Scape with faint, fine longitudinal sculpture on inner surface and several setae on ventral and dorsal margins (Fig. 3 ). Fu4 with 1 mps, fu5 and fu6 each with 2 mps, clava with 2, 2, and 4 mps on segments 1-3, respectively; funicle with segments enlarging towards apex, each with apex squarely truncate and each with numerous fairly long setae (Figs 3 , 4 ). Length/width (ratio) (holotype): scape ~320/30 (10.55); pedicel 76/36 (2.11), fu1 59/16 (3.08); fu2 114/19 (5.96); fu3 105/18 (5.70); fu4 93/21 (4.46); fu5 83/26 (3.19); fu6 72/28 (2.57), clava 185/47 (3.92). Mesosoma. Pronotum with 2 minute submedial and 2 longer sublateral setae. Mesoscutum with faint engraved reticulate sculpture, 1 adnotaular seta and 1 lateral seta on lateral lobe. Scutellum with faint engraved reticulate sculpture, campaniform sensilla midway between anterior and posterior margins and closer to each other than to scutellar seta, scutellar seta at margin of axillular carina, a minute seta/pit? anterior to apex of scutellar carina, and fenestra an isosceles triangle with rounded angles; axilla with 1 lateral seta and faint engraved reticulate sculpture; frenum with faint reticulate sculpture becoming longitudinal at lateral margin. Propodeum with 2 minute propodeal setae well separated from spiracle and with reticulate sculpture. Wings. Fore wing with a single line of microtrichia separating bare space posterior to parastigma from bare space anterior to retinaculum; hypochaeta close to proximal macrochaeta; wing length (holotype) 1210, width 222, length/width 5.46, longest marginal setae 312, venation length 739. Hind wing with a median row of about 15 microtrichia mostly in apical half beyond venation; wing length 1224, width 36, longest marginal setae 216, venation length 376. Legs. Metatibia with setae at least 2 × as long as tibial width (Fig. 6 ). Metasoma. Petiole ~0.4 × as long as wide, distinctly narrower than gt1 (Figs 6 , 9a ). Gaster with segments subequal in length except gt1 slightly shorter; gt7 triangular, apically truncate. Gt1 with 2 sublateral setae, gt6 and gt7 each with 1 submedian setae, remaining terga with 3 (sometimes 2) submedian/sublateral setae. Ovipositor length 833, ~1.8 × as long as metatibia, and exserted length 400.

Biology.

Unknown.
