Description

FEMALE ( holotype and paratypes). Length 700–925. Head and body brown to dark brown, appendages light brown to brown.

Vertex with fine cellulate sculpture, with short, weak setae; face smooth. Ocelli very small.

Antenna ( Fig. 107 View FIGURES 107–110 ). Scape with weak cross-ridges, about 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; F3, F5 and F6 subequal in length; F5 and F6 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 much wider than long, a little longer than scutellum. Axillar seta weak. Scutellum with row of small frenal foveae. Propodeum with submedial carinae short.

Wings shortened (degree of reduction varies). Forewing ( Fig. 108 View FIGURES 107–110 ) with 3 to 5 rows of setae behind venation; marginal cilia very short, greatly reduced. Hind wing with marginal cilia greatly reduced.

Metasoma longer than mesosoma. Petiole ( Fig. 109 View FIGURES 107–110 ) subquadrate, about as long as wide. Ovipositor about 4/5 length of gaster, barely exserted beyond apex of gaster; ovipositor length: metatibia length 1.5–1.6:1.

Measurements ( holotype): Mesosoma: 303; mesoscutum: 109; scutellum: 97; petiole: 67; gaster: 479; ovipositor: 409. Antenna: scape (including radicle): 130; pedicel: 54; F1: 46; F2: 82; F3: 62; F4: 52; F5: 61; F6: 61; clava: 135. Forewing: 546/103; longest marginal cilia: 18. Hind wing: 466/15. Legs (given as coxa, femur, tibia, tarsus): fore: 70, 167, 167, 203; middle: 70, 161, 246, 207; hind: 70, 145 (at an angle), 261, 249.

MALE ( paratypes). Length 660–760. Similar to female except for normal sexually dimorphic features, such as antenna and genitalia. Brachypterous (forewing as in Fig. 108 View FIGURES 107–110 ) or fully winged; if fully winged, forewing ( Fig. 110 View FIGURES 107–110 ) about 4.5 x as long as wide, with 3 or 4 rows of setae behind venation, longest marginal cilia about 3/4 forewing width, and hind wing about 35 x as long as wide.

Diagnosis

Boccacciomymar (P.) tak is unique among the known species of the subgenus B. ( Prosto ) in having shortened wings in females (and sometimes, but not always, in males) and a rectangular petiole in both sexes.

Etymology The specific name, treated here as a noun in apposition, stands for "so" in Russian.
