(Siberia).

D e s c r i p t i o n: ♀: Body length 12-13 mm. Flagellum with 38-40 flagellomeres; 1 st flagellomere 3.9-4.0× and 2 nd flagellomere 3.1-3.3× longer than wide, FI 0.85-0.95; widest flagellomeres 1.0-1.2× wider than long. Temple strongly and linearly narrowed behind eye. OED 1.0× ocellar diameter. Frons coarsely granulate, dull. Face and clypeus densely rugose-punctate. Gena rugose-punctate, in profile 0.65× as wide as eye. MI 0.8- 1.0 Genal carina straight ventrally, hypostomal carina low.

Mesosoma covered with short pale hairs. Side of pronotum finely rugose dorsally, partly striate ventrally. Notaulus impressed in frontal 0.3 of mesoscutum. Lateral lobe of mesoscutum coarsely granulate, dull. Mesopleuron densely and finely rugose-punctate. Speculum punctate, usually smooth between punctures. Epicnemial carina low. Metapleuron rugose-punctate. Juxtacoxal carina usually absent. Scutellum slightly longer than wide, distinctly elevated, with lateral carina in basal 0.1-0.3. Area superomedia wider than long, rectangular or halfmoon-shaped. Anterior transverse carina weak or absent. Area petiolaris rugose. Apophysis present. Coxae densely rugose-punctate. Hind femur 5.1-5.6× longer than wide. Postpetiolus slightly widened, 0.6× as wide as distance between apophyses, lateral field 0.3× as wide as median field, median field granulate or finely rugose. Gastrocoelus indistinct. Thyridium weakly impressed, slightly oblique, 0.4× as wide as the interval. 2 nd tergite 1.2× wider than long. 2 nd tergite finely rugose-punctate, 3 rd tergite granulate, 4 th tergite almost smooth and shining. Ovipositor sheath 0.65-0.7× as long as hind metatarsus.

Color: black or ± reddish (often head, meso- and metasoma, flagellum and legs). Flagellomere 7/8-11/12, wide stripe on frontal orbit, sometimes spot on vertex and on outer orbit, scutellum and sometimes postscutellum yellowish. Tergites reddish, 4 th to 7 th tergite often ± infuscate. Femora often ± blackish. Pterostigma ochreous.

♁: Body length 11-12 mm. Flagellum with 36-38 flagellomeres; 1 st flagellomere 2.9- 3.1× and 2 nd flagellomere 2.2-2.5× longer than wide, FI 0.78-0.82. Tyloids on flagellomeres 7/8-15/16, oval, basad on flagellomere and maximally 0.7× as long. OED 1.0-1.2× ocellar diameter. Gena 0.6× as wide as eye. MI 0.6. Mesopleuron densely and finely rugose-punctate, speculum partly smooth and shining. Scutellum about as long as wide, distinctly elevated, with lateral carina in basal 0.1. Area superomedia slightly transverse, halfmoon-shaped. Anterior transverse carina absent. Hind femur 4.9× longer than wide. Postpetiolus slightly widened, 0.6× as wide as distance between apophyses. 2 nd tergite 1.1× wider than long. Apical margin of hypopygium rounded medially.

Color: as in ♀, but yellow coloration usually more extended: flagellomeres 10-12 (in one specimen flagellomeres 3-7 dorsally), clypeus, face, frontal orbit, vertex, outer orbit, scape ventrally, frontal and upper margins of pronotum, subtegular ridge, scutellum, postusctellum, often fore and mid coxae and legs yellowish.
