Valentine (E1121) [ 11♀ on 3 cards (6, 3, and 2 respectively), 1Ƌ on slide, NZAC ] . Description. FEMALE ( holotype ). Body and appendages dark brown except petiole and legs (the latter partially) brown (as in Fig. 79 ). Head ( Fig. 76 ) wider than high; face with fine, inconspicuous subtorular lines. Antenna ( Fig. 73 ) with scape, including short radicle, 3.3× as long as wide, smooth; pedicel smooth, longer than F1 and 2.0× as long as wide; F1 the shortest and F2 the longest funiculars, F3 as long as F6 and longer than F4 or F5, length to width ratios of funiculars: F1—2.3, F2—6.1; F3—4.2; F4—2.4; F5—2.2; F6—2.6, F6 with 1 mps; clava 2.6× as long as wide, about as long as combined length of 3 preceding flagellomeres, with 7 mps. Mesosoma about 1.7× as long as wide, mostly smooth except mesoscutum with fine, inconspicuous mesh-like sculpture; pronotum entire; mesoscutum wider than long, with notaular grooves; scutellum shorter than mesoscutum, with campaniform sensilla closer to anterior than to posterior margin and widely separated from each other but at a distance from lateral margins (as in Fig. 81 ), and with frenal row of small foveae; propodeum ( Fig. 75 ) with a median carina extending from posterior margin for about half length. Fore wing ( Fig. 78 ) 5.0× 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 1.0× greatest width of wing. Hind wing about 33× as long as wide; disc slightly infumate, with an incomplete median row of setae; longest marginal seta 5.3× greatest width of wing. Metacoxa almost smooth. Petiole with anterolateral “wings”. Ovipositor occupying almost entire length of gaster ( Fig. 77 ), exserted beyond gastral apex by 0.14× own total length, and 1.7× length of metatibia. Measurements of the holotype (µm). Mesosoma: 320; gaster: 449; ovipositor: 486. Scape: 121; pedicel: 60; F1: 30; F2: 85; F3: 55; F4: 38; F5: 41; F6: 55; clava: 136. Fore wing: 898:179; longest marginal seta: 182. Hind wing: 763:23; longest marginal seta: 121. Variation ( paratypes ). Body length (dry-mounted specimens, as in Fig. 79 ) 825–960 µm . In the slide-mounted specimen, scape, including radicle, 3.5× as long as wide, clava 2.3× as long as wide, fore wing 5.5× as long as wide, longest marginal seta 1.3× greatest width of fore wing, and ovipositor exserted beyond gastral apex by about 0.1× own total length, and 1.6× length of metatibia. FIGURES 73–78. Polynema ( Polynema ) grafinya , female (holotype): 73, antenna; 74, slide; 75, propodeum; 76, head in frontal view; 77, gaster; 78, fore wing. FIGURE 79. Polynema ( Polynema ) grafinya , habitus of female in lateral view (paratype, Red Hills, Wairau, South Island, New Zealand). MALE ( paratype ). Similar to female in color except petiole ( Fig. 81 ) brown. Antenna ( Fig. 80 ) with scape, excluding radicle, 2.2× long as wide and shorter than any funicular. Fore wing ( Fig. 82 ) 5.4× as long as wide; longest marginal seta 1.1× greatest width of wing. Genitalia typical for species of P. ( Polynema ) ( Triapitsyn & Fidalgo 2006 ), 230 µm long; digitus with 2 small denticles apically . Diagnosis. Polynema grafinya females can be separated from females of other fully winged species of the draperi group by its relatively long ovipositor, at least 1.6× the length of the metatibia, that occupies almost the entire length of the gaster and is exserted beyond the gastral apex by at least 0.1× its own total length ( Fig. 77 ). Etymology. The species name is a noun in apposition; it means countess in Russian. Remarks. Three females [NZAC] from South Island, New Zealand, labeled: “ NEW ZEALAND , OL, Kinloch SF, Dart R, Jan. 1981 , Nothofagus For Broadleaf , grass P. totara Swept, J. S. Noyes, E. W. Valentine ” may also belong to this species; however, they have a relatively narrower fore wing (5.7–6.0× as long as wide) and a shorter ovipositor (about 1.5× as long as metatibia).
