( Figs 18–20 View FIGURES 18–20 )

Type material

Holotype female (on slide, CNCI): PAPUA NEW GUINEA, East New Britain, Bainings Mountains , 15– 28.iv.1999, L. Leblanc, M. Kalaman, flight intercept traps / yellow pan traps, base camp, DPI station, river.

Paratype: PAPUA NEW GUINEA: same data as holotype [1 female on card, CNCI] .

Description

FEMALE (holotype and paratype). Length about 1600. Head and mesosoma mostly dark brown; petiole light brown; gaster mostly brown, middle terga slightly darker; exserted parts of ovipositor sheaths brown. Scape, pedicel, F1, and F5 light brown; F2–F4 brown (apex of F4 slightly lighter); F6 and clava dark brown. Wing venation brown. Legs mostly light brown except procoxa, protrochanter, and profemur brown.

Head with toruli slightly above mid level of eyes. Mandibular teeth more or less sharp.

Antenna ( Fig. 18 View FIGURES 18–20 ). Scape with cross-ridges, about 2.0 x as long as wide in lateral view; pedicel shorter than F1; F2 the longest funicle segment, slightly longer than F3; F4 and F5 subequal and as long as F1; F6 shortest; all funicle segments without longitudinal sensilla; clava about 3.0 x as long as wide, with 9 longitudinal sensilla.

Pronotum almost smooth; mesoscutum and scutellum with fine cellulate sculpture; propodeum notably wrinkled, its anterior margin with peculiar sculpture ( Fig. 19 View FIGURES 18–20 ). Pronotum entire, a little shorter than mesoscutum, with at least 5 pairs of setae. Mesoscutum notably longer than scutellum. Axilla with 1 row of 3 or 4 large foveae and 1 small fovea and a weak but rather long seta. Scutellum with row of frenal foveae. Submedial carinae extending to more than 1/2 length of propodeum ( Fig. 19 View FIGURES 18–20 ).

Forewing ( Fig. 20 View FIGURES 18–20 ) 3.9–4.0 x as long as wide; marginal vein with 1 dorsal macrochaeta and a seta on membrane just next to (anterior to) marginal vein; marginal fringe moderately short, longest marginal cilia about 2/5 greatest width of wing; approximately basal 1/3 of blade bare; remainder of blade densely setose (with modified setae of types F, and G, and normal setae) and with two brown spots: the larger, elongated spot along anterior margin in apical half of the blade, the smaller, short spot at posterior margin in the widest part of blade. Apical half or so of hind wing blade slightly infumate; longest marginal cilia about 4 x greatest width of blade.

Coxae and femora almost smooth, base of metafemur with whorls of fine, white setae. Protibia with 2 rows of 7 or 8 conical sensilla.

Petiole a little longer than metacoxa. Ovipositor about 9/10 length of gaster, markedly exserted beyond its apex (by about 3/10 of its own length); ovipositor length: metatibia length 2.0:1.

Measurements (holotype): Mesosoma: 633; mesoscutum: 215; scutellum: 158; petiole: 206; gaster: 830; ovipositor: 1101. Antenna: scape (excluding radicle): 103; pedicel: 76; F1: 97; F2: 167; F3: 159; F4: 97; F5: 97; F6: 85; clava: 263. Forewing: 1494/379; longest marginal cilia: 160. Hind wing: 1193/36. Legs (given as coxa, femur, tibia, tarsus): fore: 152, 333, 312, 476; middle: 136, 321, 427, 616; hind: 197, 355, 551, 658.

MALE. Unknown.

Diagnosis

Possibly a member of the indochinense species group. This species is characterized by a long, markedly exserted ovipositor, long tarsi, a notably sculptured propodeum at the anterior margin ( Fig. 19 View FIGURES 18–20 ), distinctive color of the female funicle segments (F5 light brown, F6 dark brown), and a mostly densely setose forewing with two brown spots at margins.

Etymology The specific name (a noun in apposition) stands for a female stranger in Russian.
