D e s c r i p t i o n: ♀: Body length 9.5 mm. Flagellum almost filiform, with 38 flagellomeres; 1 st flagellomere 2.0× longer than wide, 7 th flagellomere square, widest flagellomeres c. 1.3× wider than long; preapical flagellomere 0.80× as long as wide. Temple moderately and roundly narrowed behind eyes, dorsally 0.75× as long as eye. OED 1.4× and OOD 1.6× ocellar diameter. Frons coarsely punctate. Face and clypeus with rather dense punctures, smooth and shining between punctures. Clypeus slightly convex, with sharp, slightly concave apical margin. Gena 1.0× as wide as eye, with scattered punctures ventrally. Mandible with two teeth, lower tooth smaller than upper tooth. MI 0.85; malar space 0.70× as long as 1 st flagellomere. Genal carina complete, reaching hypostomal carina far from mandibular base; both carinae low.
Mesosoma covered with short whitish hairs. Mesoscutum with fine and rather dense punctures, shining. Mesopleuron with scattered punctures ventrally and denser punctures dorsally. Mesosternum with very scattered punctures, partly smooth. Metapleuron striate-punctate; juxtacoxal carina present. Scutellum slightly elevated, about as long as wide, with fine scattered punctures, without lateral carina. Propodeum rugose; area externa with fine oblique striae. Area superomedia rugose, 1.1× wider than long, with slightly curved sides, apical carina slightly concave. Mid and hind coxae with very scattered punctures ventrally; hind coxa with small brownish scopa apico-ventrally. Hind femur 3.8× longer than wide, with very scattered punctures and almost smooth in ventral half. Tarsi slender, 3 rd mid tarsomere 1.6× longer than wide.
Metasoma strongly oxypygous, hypopygium short. Postpetiolus moderately widened, lateral field finely striate and punctate, 0.55× as wide as median field; median field with c. 12 fine striae. 2 nd tergite 0.83× as long as wide. Gastrocoelus impressed, with strong longitudinal ridges. Thyridium narrow, slightly oblique, 1.0× as wide as the interval. 2 nd
tergite densely punctate, partly rugose-punctate but not striate medially. 3 rd tergite with dense, ± superficial punctures. Ovipositor sheath extending behind metasomal apex by half length of 7 th tergite.
Color: black. Flagellum without distinct pale ring; basal flagellomeres black, flagellomeres 10-14 ochreous, distal flagellomeres brownish. Apical margin of 2 nd tergite narrowly reddish. Coxae, trochanters and fore and mid legs mainly black; fore and mid femora apically and tibiae subbasally reddish; hind femur red; hind tibia red, infuscate in apical 0.3; hind tarsus black. Wings ± brownish; pterostigma black.
♁ unknown.
R e m a r k: The color pattern of this new species resembles Ichneumon cessator MÜLLER , but the new species can be differentiated by its smaller size, almost filiform flagellum, scattered punctures on ventral mesopleuron, mesosternum and mid and hind coxae, and a small scopa on hind coxa.
