Virgichneumon paramonostagon nov.sp. ( figs 26 View Figs 23-26 , 102-104 View Figs 102-104 )
H o l o t y p e: (♀) "Far East Russia, Primorje region, Sikhote-Alin Mountain, Sokolci, 1.VII.1991 " (Linz).
D e s c r i p t i o n: ♀: Body length 12 mm. Flagellum with 37 flagellomeres, slightly lanceolate; 1 st flagellomere and 2 nd flagellomere each 2.0× longer than wide, combined length 0.55× eye length. 10 th flagellomere square; widest flagellomeres 1.3× wider than long. Temple moderately and roundly narrowed behind eyes. Frons coarsely and densely punctate. OED 1.3× and OOD 1.6× ocellar diameter. Face densely punctate, dull. Clypeus with scattered and finer punctures, shining; apical margin sharp and straight. Gena 1.1× wider than eye, with dense punctures ventrally. Mandible with two teeth, lower tooth smaller than upper tooth. MI 0.9. Genal carina reaching hypostomal carina away from mandibular base, both carina low.
Mesosoma covered with grey hairs. Notaulus impressed in frontal 0.2 of mesoscutum. Mesoscutum coarsely punctate, ± dull. Mesopleuron and metapleuron coarsely and densely punctate. Juxtacoxal carina present. Scutellum almost flat, slightly wider than long, with scattered punctures, without lateral carina. Area basalis with strong median tubercle. Area superomedia heart-shaped, about as long as wide, rugose; anterior transverse carina in its middle. Area petiolaris slightly impressed medially, with coarse rugae. Hind coxa densely punctate, punctures very fine and dense ventro-apically, but without distinct scopa. Hind femur densely and finely punctate, 3.8× longer than wide. Hind tibia without denticular spurs externally. Areolet pentagonal, frontal distance between veins 2rs-m and 3rs-m 3× their diameter; vein 2m-cu distad its middle. Vein 1cu-a interstitial.
Postpetiolus strongly widened and completely and coarsely punctate; lateral field 0.8× as wide as median field; dorsal carina present. Gastrocoelus almost triangularly impressed, with longitudinal ridges. Thyridium oblique, 0.6× as wide as interval. 2 nd tergite 0.7× as long as wide. 2 nd and 3 rd tergites densely rugose-punctate, ± dull. 4 th tergite with very superficial punctures, shining. Ovipositor sheath slightly extending behind metasomal apex.
Color: black. Stripes on flagellomeres 9-14, small orbital spot opposite anterior ocellus, scutellum and wide median spots on 6 th and 7 th tergites yellow. Side of clypeus with weak ochreous spot. Legs black; fore tibia with ochreous stripe frontally. Wings hyaline. Pterostigma blackish.
R e m a r k: This new species strongly resembles the European Virgichneumon monostagon (GRAVENHORST) , but differs by lower number of flagellomeres, slenderer 2 nd flagellomere, finely punctate ventro-apical area on hind coxa and lack of external denticular spurs on hind tibia.
