D e s c r i p t i o n: ♀: Body length 13.5 mm. Flagellum filiform, with 40 flagellomeres; 1 st flagellomere 2.0× longer than wide, 7 th flagellomere square, widest flagellomeres c. 1.3× wider than long; preapical flagellomere 0.60× as long as wide. Temple slightly widened behind eyes and narrowed apically, dorsally 0.9× as long as eye. OED 1.5× and OOD 1.5× ocellar diameter. Frons coarsely rugose-punctate. Face densely punctate, partly rugose. Clypeus almost flat, with scattered punctures; apical margin sharp and straight. Gena wide, 1.5× as wide as eye, with scattered punctures ventrally. Mandible with two teeth, lower tooth smaller than upper tooth. MI 1.2; malar space 1.0× as long as 1 st flagellomere. Genal carina complete, reaching hypostomal carina far from mandibular base; both carinae low.
Mesosoma covered with short brown hairs. Mesoscutum with fine and rather dense punctures, shining. Mesopleuron densely punctate, rugose-punctate in posterior half. Metapleuron coarsely rugose-punctate; juxtacoxal carina present. Scutellum almost flat, about as long as wide, with fine scattered punctures, without lateral carina. Propodeum rugose-punctate. Area superomedia rectangular, about as long as wide; anterior transverse carina absent. Hind coxa densely punctate, with short brownish scopa (1/3 coxal length). Hind femur 3.8× longer than wide, with very scattered punctures in ventral half. Tarsi rather slender, 3 rd mid tarsomere 1.5× longer than wide.
Metasoma strongly oxypygous, hypopygium short. Postpetiolus moderately widened; lateral field rugose, 0.6× as wide as median field; median field with c. 14 strong striae. 2 nd tergite 0.75× as long as wide. Gastrocoelus impressed, with 3-4 ridges. Thyridium narrow, slightly oblique, 0.8× as wide as the interval. 2 nd tergite finely and densely rugose-punctate, finely striate medially. 3 rd tergite superficially rugose-punctate. 7 th tergite strongly narrowed posteriorly, metasomal apex almost pointed. Ovipositor sheath slightly extending behind metasomal apex.
Color: black. Flagellum without distinct pale ring, flagellomeres 8-10 with weak reddish shine. Mandible reddish centrally. Head, mesosoma and metasoma black; 2 nd tergite with weak brownish shine. Coxae and trochanters black; legs otherwise including trochantelli red; distal tarsomeres ± brownish. Wings with brownish infuscation; pterostigma black.
♁ unknown.
R e m a r k: This new species resembles Ichneumon melanosomus WESMAEL , but differs by its wider temple, slenderer hind femur, entirely black apical tergites and reddish hind tarsus.
