Description. FEMALE ( holotype). Body dark brown except petiole as well as basal and apical gastral terga slightly lighter brown, appendages brown. Head ( Fig. 132 View FIGURES 130–135 ) wider than high; face with faint subtorular lines. Antenna ( Fig. 131 View FIGURES 130–135 ) with scape (excluding radicle) 3.25× as long as wide, smooth; pedicel smooth, longer than F1 and 1.8× as long as wide; F1 the shortest and F2 the longest funiculars, F3 almost as long as F6 and longer than F4 or F5, length to width ratios of funiculars: F1—2.2, F2—5.7; F3—3.9; F4—2.2; F5—2.0; F6—2.2, F6 with 1 mps; clava 2.5× as long as wide, almost as long as combined length of 3 preceding flagellomeres, with 7 mps. Mesosoma ( Fig. 134 View FIGURES 130–135 ) about 1.4× as long as wide, mostly smooth except mesoscutum with fine, inconspicuous mesh-like sculpture; pronotum divided mediolongitudinally; mesoscutum wider than long, with notaular grooves; scutellum shorter than mesoscutum, with campaniform sensilla very close, within a diameter of a sensillum, to anterior margin, and each closer to lateral margin of scutellum than to each other, and with frenal row of foveae; propodeum ( Fig. 133 View FIGURES 130–135 ) with median carina extending from posterior margin for almost half length. Fore wing ( Fig. 135 View FIGURES 130–135 ) 4.7× as long as wide; marginal vein with 1 dorsal macrochaeta; disc slightly infumate, densely setose beyond venation, the discal setae originating behind apex of submarginal vein; longest marginal seta almost 1.0× greatest width of wing. Hind wing 25× as long as wide; disc slightly infumate, with median row of setae; longest marginal seta 4.4× greatest width of wing. Metacoxa smooth, about as long as petiole. Petiole ( Fig. 134 View FIGURES 130–135 ) 2.1× as long as wide, with anterolateral “wings”. Ovipositor occupying 0.9 length of gaster ( Fig. 134 View FIGURES 130–135 ), exserted beyond gastral apex by 0.08× own total length, and 1.1× length of metatibia.

Measurements of the holotype (µm). Mesosoma: 351; gaster: 387; ovipositor: 381. Scape (excluding radicle): 118; pedicel: 60; F1: 33; F2: 85; F3: 55; F4: 39; F5: 42; F6: 57; clava: 152. Fore wing: 1002:215; longest marginal seta: 209. Hind wing: 830:33; longest marginal seta: 145.

MALE. Unknown.

Diagnosis. Polynema rangatira females are recognized by the following combination of features: face with faint subtorular lines ( Fig. 132 View FIGURES 130–135 ), scape without cross-ridges ( Fig. 131 View FIGURES 130–135 ), fore wing ( Fig. 135 View FIGURES 130–135 ) 4.7× as long as wide, and ovipositor ( Fig. 134 View FIGURES 130–135 ) 1.1× length of metatibia. Otherwise females are somewhat similar to those of P. grafinya which have an entire, medially undivided pronotum, and a notably longer ovipositor that is at least 1.6× length of the metatibia.

Etymology. The species name is a noun in apposition; it means chief (male or female) or wellborn/noble in Mâori (te reo).
