D e s c r i p t i o n: ♀: Body length 13 mm. Flagellum almost filiform, with 43 flagellomeres; 1 st flagellomere 1.8× longer than wide, 7 th flagellomere square, widest flagellomeres 1.25× wider than long; preapical flagellomere 0.70× as long as wide. Head covered with short brownish hairs. Temple slightly and roundly narrowed behind eyes, dorsally 0.8× as long as eye. OED 1.7× and OOD 2.0× ocellar diameter. Frons rugose-punctate. Face punctate, partly rugose-punctate medially. Clypeus almost flat, with scattered punctures. Gena 1.3× as wide as eye, with scattered punctures ventrally. Mandible with lower tooth smaller than upper one. MI 1.2; malar space 1.2× as long as 1 st flagellomere. Genal carina complete, reaching hypostomal carina far from mandibular base; both carinae low.
Mesosoma covered with pale brownish hairs. Mesoscutum densely punctate laterally and rugose-punctate medially. Mesopleuron striate and rugose-punctate. Metapleuron coarsely and densely rugose-punctate; juxtacoxal carina present. Scutellum slightly elevated, wider than long, with fine scattered punctures, without lateral carina. Propodeum rugose. Area superomedia rectangular, 1.15× wider than long; anterior transversal carina absent. Hind coxa with dense punctures and small roundish and slightly elevated brown scopa apico-ventrally. Hind femur 3.1× longer than wide, densely punctate, punctures scattered in basal 1/5. Tarsi moderately widened, 3 rd mid tarsomere 1.3x longer than wide.
Metasoma stout, oxypygous, hypopygium short. Postpetiolus moderately widened, lateral field ± striate, 0.5× as wide as median field; median field with c. 12 rather coarse striae. 2 nd tergite 0.65× as long as wide. Gastrocoelus impressed, with strong ridges. Thyridium slightly oblique, 0.9× as wide as the interval. 2 nd and 3 rd tergites very finely and densely rugose-punctate, not striate. 7 th tergite stout, slightly narrowed apically. Ovipositor sheath shortly extending behind metasomal apex.
Color: black. Scape, pedicel and flagellomeres 1-8 reddish, flagellomeres 9-14 yellowish, following flagellomeres brown. Mandible except teeth, side of clypeus, inner orbit (widened opposite lateral ocellus), central spot on face, gena, collar and tegula reddish. Scutellum reddish-yellow. 2 nd tergite entirely yellowish-red; 3 rd tergite yellowish red, with black band in anterior 1/3. 6 th and 7 th tergites with wide yellow median spots. Coxae and trochanters black; fore and mid legs reddish, their femora basally ± blackish; hind trochantellus reddish; hind femur black; hind tibia red, black in apical 0.35; hind tarsus black. Wings with brownish infuscation; pterostigma reddish.
♁ unknown.
R e m a r k: Due to the color pattern of metasoma and its small scopa, this new species resembles Ichneumon altaicola HEINRICH , but differs by: flagellum stouter, scape, pedicel and basal flagellomeres red, hind femur stouter and hind tarsus entirely black.
Ichneumon pilulicornis HEINRICH, 1978 M a t e r i a l e x a m i n e d: Mongolia, Övörkhangay, 12 km SW Arvaykheer, 46.22°N
102.49°E, 1770 m, 2♀♀ 3.VII.2004, leg. J. Halada (Linz).
R e m a r k: The Mongolian specimens are smaller than the holotype from Far East Russia: body length 10.5 mm, flagellum with 31 flagellomeres. Face ± and hind edge of pronotum reddish, otherwise typical.
D i s t r i b u t i o n: Far East Russia, new record for Mongolia.
