(Figs 124–129)
Type material. Holotype female [ANIC] on slide (Fig. 124) labeled: 1. “ 14.49S 125.50E, Mining Camp, Mitchell Plateau, 9-19May 1983 WA I. D. Naumann, J. C. Cardale, ex yellow tray”; 2. “Mounted at UCR/ERM by V. V. Berezovskiy 2006 in Canada balsam ANIC ”. Paratypes: same data as the holotype [5♀ on slides, ANIC (4), UCRC (1)]. The type locality is in Western Australia, Australia.
Description. FEMALE (holotype). Body dark brown except petiole light brown; scape and pedicel light brown, flagellum brown; legs light brown. Head a little wider than high, smooth. Antenna (Fig. 125) with scape, excluding short radicle, 2.8× as long as wide, with cross-ridges; pedicel smooth, longer than F1 and 1.5× as long as wide; F1 the shortest and F2 the longest funiculars, F3 longer than F4 or F5, length to width ratios of funiculars: F1—2.4, F2—6.1; F3—5.2; F4—2.7; F5—2.6; F6—2.5, F6 with 1 mps; clava 2.7× as long as wide, a little longer than combined length of 2 preceding flagellomeres, with 7 mps. Mesosoma (Fig. 126) about 1.4× as long as wide, mostly smooth except mesoscutum with fine, transverse sculpture anteriorly; pronotum divided mediolongitudinally; mesoscutum wider than long, with notaular grooves; scutellum shorter than mesoscutum, with campaniform sensilla a little closer to anterior margin than to posterior margin and each closer to lateral margin of scutellum than to each other, and with frenal row of small foveae; propodeum with a short median carina extending from posterior margin for about quarter length. Fore wing (Fig. 128) 4.1× as long as wide; marginal vein with 2 dorsal macrochaetae; disc slightly infumate, densely setose beyond venation, the discal setae originating behind marginal vein; longest marginal seta about 0.9× greatest width of wing. Hind wing 28.5× as long as wide; disc slightly infumate, with a few setae; longest marginal seta 5.0× greatest width of wing. Metacoxa smooth, shorter than petiole. Petiole (Fig. 129) with small anterolateral “wings”. Ovipositor occupying entire length of gaster (Fig. 127), barely exserted beyond gastral apex, and 1.8× length of metatibia.
Measurements of the holotype (µm). Mesosoma: 308; gaster: 492; ovipositor: 492. Scape (minus radicle): 94; pedicel: 58; F1: 33; F2: 85; F3: 73; F4: 46; F5: 55; F6: 61; clava: 132. Fore wing: 861:209; longest marginal seta: 194. Hind wing: 683:24; longest marginal seta: 121.
Variation (paratypes). Pronotum and base of gaster sometimes light brown or brown. Scape, excluding radicle, 2.2–2.7× as long as wide, clava 2.6–2.8× as long as wide and sometimes about as long as or slightly shorter than combined length of F5 and F6, fore wing 4.0–4.3× as long as wide, longest marginal seta 0.7–1.0× greatest width of fore wing, petiole about 2.4× as long as wide, and ovipositor 1.6–1.7× length of metatibia, exserted beyond gastral apex by 0.05–0.11× its total length.
MALE. Unknown.
Diagnosis. Polynema princessa females are recognized by the following combination of features: scape with cross-ridges (Fig. 125), clava about as long, slightly longer or shorter than, combined length of F5 and F6, propodeum (Fig. 126) with a short, incomplete median carina extending from posterior margin for about quarter length, fore wing (Fig. 128) 4.0–4.3× as long as wide, and ovipositor occupying entire length of gaster (Fig. 127), and 1.6–1.8× length of metatibia.
Etymology. The species name is a noun in apposition; it means princess in Russian.
