Ichneumon lanceolator nov.sp. ( figs 7 View Figs 5-8 , 28 View Figs 27-32 , 51 View Figs 49-52 , 70 View Figs 69-72 )
M a t e r i a l e x a m i n e d: Holotype: ♀ " 1-5 vii 2003, 2000 m, SW Tannu-Ola Mt rng, Sogly vill, SW Tuwa reg., S Siberia, leg. Vastchenko " (coll. Riedel).
D e s c r i p t i o n: Body length 10.2 mm. Antenna very stout and strongly lanceolate, with 35 flagellomeres; 1 st flagellomere 1.1x longer than wide, 2 nd flagellomere square; widest flagellomeres c.0.5x as long as wide; preapical flagellomere 0.9x as long as wide. Temple slightly and roundly narrowed behind eye. OOD 1.6. Frons coarsely rugosepunctate. Face centrally with dense punctures, smooth between punctures; facial orbit and clypeus with scattered punctures. Gena 1.1x as wide as eye, with rather dense punctures in ventral 1/2. Malar space 1.15x as long as width of mandibular base and 1.25x as long as 1 st flagellomere. Genal carina complete, not interrupted ventrally. Hypostomal carina narrow.
Mesosoma covered with brownish hairs. Mesoscutum densely punctate, lateral field centrally with scattered punctures. Mesopleuron densely punctate, smooth between punctures. Metapleuron coarsely rugose-punctate; coxal carina present. Scutellum slightly elevated, wider than long, with scattered punctures. Area superomedia rectangular, 1.5x wider than long; costula absent. Area petiolaris without lateral border. Mid coxa with scattered punctures ventrally, hind coxa with dense punctures, without scopa. Hind femur 3.3x longer than wide, with very scattered punctures in ventral 1/3. Hind tibia with c.9 denticular spurs apico-externally. Fore and mid tarsomeres moderately enlarged, 3 rd mid tarsomere c.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 and very superficial aciculation. 2 nd tergite very wide, 0.63x as long as wide. Gastrocoelus impressed, with weak ridges. Thyridium small, transverse, c.0.5x as wide as the interval. 2 nd and 3 rd tergites with fine and very dense punctures, finely granulate, but without longitudinal rugosity medially. Ovipositor sheath slightly extending beyond metasomal apex.
Color: Black. Mandible except teeth, side of clypeus, facial and frontal orbits, scapus, pedicel and flagellomeres 1-10 red. Collare and hind edge of pronotum, tegula and scutellum red. Postpetiolus apically and 2 nd and 3 rd tergites completely red. 6 th and 7 th tergites with rather large ivory spots medially. Coxae and trochanters black, fore and mid coxae frontally and all trochanters apically red. Legs otherwise red; hind femur black centrally, red in basal 0.1 and apical 0.2. Wings with slight 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 G 4 sensu HILPERT, but differs from all known species in this group by the stout and strongly lanceolate flagellum and the red color pattern of basal antenna, scutellum and legs. It resembles Ichneumon grandicornis THOMSON (group E) due to the structure of flagellum, but differs by the red color pattern, absent scopa of hind coxa, stouter metasoma and wider area superomedia.
