. Antenna moderately lanceolate, with 37 flagellomeres; 1
st
flagellomere 1.8x longer than wide, c.8
th
flagellomere square, widest flagellomeres c.0.75x as long as wide; preapical flagellomere 0.9x as long as wide. Temple rather long, slightly narrowed behind eye. OOD 1.5. Frons coarsely and transversely rugose-punctate. Face coarsely and densely punctate, with fine granulation. Clypeus with dense punctures, smooth between punctures. Gena 1.2x as wide as eye, with dense punctures and fine striation in ventral 1/2. Malar space 1.25x as long as width of mandibular base and 1.15x as long as 1
st
flagellomere. Genal carina complete, not interrupted ventrally. Hypostomal carina slightly elevated.
Mesosoma covered with brownish hairs. Mesoscutum coarsely and densely punctate, with fine granulation but shining. Mesopleuron and metapleuron coarsely rugosepunctate; coxal carina present. Scutellum moderately elevated, about as long as wide, with rather dense punctures becoming finer apically. Area superomedia slightly hexagonal, 1.2x wider than long; costula absent.

Color: Black. Scapus, pedicel and flagellomeres 1-8 red, flagellomeres 9-12 more yellowish-red. Mandible shortly red centrally. Collare, tegula and scutellum red. 2

T a x o n o m i c a l r e m a r k The species belongs to group C sensu

and runs to
Ichneumon norvegicus

in his key. It differs by less widened median flagellomeres, reddish scapus, pedicel, scutellum and 2

tergite and an ivory spot on 6
