M a t e r i a l e x a m i n e d Holotype: ♀ " S Siberia, Hakassia reg., Sallyghen-Taiga mt.
reg., 2400 m, 10 vii 2005, leg. Osipov" (coll. Riedel).
D e s c r i p t i o n: Body length 11 mm. Antenna almost filiform, with 43 flagellomeres; 1 st flagellomere 1.5x longer than wide, c.7 th flagellomere square, widest flagellomeres c.0.75x as long as wide; preapical flagellomere 0.67x as long as wide. Temple slightly widened behind eye and slightly narrowed apically. OOD 1.8. Frons densely rugose-punctate and granulate. Face coarsely punctate and finely granulate; clypeus rather densely punctate, smooth between punctures. Gena wide, 1.4x as wide as eye, with scattered punctures in ventral 1/2. Malar space 1.25x as long as width of mandibular base and 1.3x as long as 1 st flagellomere. Genal carina complete, not interrupted ventrally. Hypostomal carina narrow.
Mesosoma covered with brownish hairs. Mesoscutum densely punctate and finely granulate medially, lateral field with rather dense punctures centrally, smooth between punctures. Mesopleuron densely punctate, partly rugose; metapleuron coarsely rugosepunctate; coxal carina present. Scutellum slightly elevated, slightly longer than wide, with rather dense punctures. Area superomedia almost square; costula absent. Area petiolaris without lateral border. Hind coxa densely punctate, with large reddish scopa (2/5 of coxal length). Hind femur 3.7x longer than wide, with very scattered punctures basally and in ventral 1/2. Hind tibia with c.3 denticular spurs apico-externally. Tarsomeres distinctly widened, 3 rd mid tarsomere 1.3x longer than wide.
Metasoma strongly oxypygous, hypopygium short. Postpetiolus strongly widened, lateral field 0.5x as wide as the median one, median field with fine irregular aciculation and some subapical punctures. 2 nd tergite 0.62x as long as wide. Gastrocoelus impressed, with fine ridges; thyridium slightly oblique, about as wide as the interval. 2 nd and 3 rd tergites very densely punctate and finely granulate, not rugose medially. Ovipositor sheath slightly extending behind metasomal apex.
Color: Black. Scapus apically and flagellomeres 1-8 red, flagellomeres 9-13 darker red, following flagellomeres black. Mandible except teeth, collare and hind edge of pronotum, tegula and scutellum red. Metasoma black; postpetiolus laterally and apically and 2 nd to 3 rd tergites laterally red; 7 th tergite with an indistinct reddish spot medially. Coxae and trochanters black; legs otherwise red. Wings with yellowish tint, pterostigma yellow.
Males unknown.
T a x o n o m i c a l r e m a r k This species belongs to group E 2 sensu HILPERT (1992). The new taxon is closely related to Ichneumon lariae taimyrensis HEINRICH, but differs by larger number of flagellomeres, black mesoscutum and distinct scopa on hind coxa.
