Description

FEMALE (holotype and paratypes). Length 790–990. Body brown to dark brown (gaster sometimes slightly lighter than head and mesosoma); petiole and appendages light brown to brown.

Vertex with fine cellulate sculpture and with short, weak setae; face with even finer, inconspicuous sculpture. Ocelli small.

Antenna ( Fig. 111 ) shorter than body. Scape with weak cross-ridges, about 3.3 x as long as wide; pedicel slightly longer than F1; F2 the longest funicle segment; F3 shorter than F2, F4 shorter than F3 or F5; F5 and F6 subequal in length, each with 1 longitudinal sensillum, slightly wider than preceding funicle segments; clava slightly longer than combined length of F5 and F6, with 8 longitudinal sensilla.

Pronotum and mesoscutum with cellulate sculpture; axilla, scutellum and metanotum with much finer, inconspicuous, sculpture. Mesoscutum a little longer than scutellum. Scutellum with row of small frenal foveae. Propodeum with submedial carinae short, narrow.

Forewing ( Fig. 112 ) 4.2–4.5 x as long as wide, usually with 3 rows of setae behind venation; longest marginal cilia 1/2–3/5 forewing width; blade slightly infumate basally and also narrowly along anterior margin beyond venation. Hind wing 35–38 x as long as wide.

Metasoma longer than mesosoma. Petiole subrectangular, about 1.2 x as long as wide. Ovipositor almost entire length of gaster, barely exserted beyond gastral apex (at most by about 1/15 of its total length); ovipositor length: metatibia length 1.5–1.6:1.

Measurements (holotype): Mesosoma: 366; mesoscutum: 124; scutellum: 112; petiole: 106; ovipositor: 518. Antenna: scape (including radicle): 136; pedicel: 58; F1: 52; F2: 85; F3: 74; F4: 59; F5: 67; F6: 65; clava: 145. Forewing: 825/182; longest marginal cilia: 91. Hind wing: 677/18. Legs (given as coxa, femur, tibia, tarsus): fore: 94, 196, 182, 227; middle: 79, 197, 273, 258; hind: 97, 227, 318, 297.

MALE (paratypes). Length 690–800. Similar to female except for the normal sexually dimorphic features, such as antenna and genitalia ( Fig. 113 ), and the following. Color darker than in female: head and body dark brown, appendages brown to dark brown. Metasoma usually shorter or sometimes about as long as mesosoma.

Diagnosis

This species resembles B. (P.) maria in having a similar forewing and antenna and B. (P.) tak in having relatively weak sculpture on the mesonotum. It differs from B. (P.) maria in having a cellulate, rather than reticulate, sculpture of the mesonotum and a wider petiole, and from B. (P.) tak in having a narrower petiole and fully winged females.

Etymology The specific name (a noun in apposition) stands for "a victory" in Russian.
