M a t e r i a l e x a m i n e d: Tajikistan,WPamirMountains,Rushandistrict, 3400 m, 3♁♁ 20-30.VII.2015, leg. V. Gurko (Linz and coll. Riedel).

D e s c r i p t i o n of ♁: Body length 14-15 mm. Flagellum with 42-43 flagellomeres; 1 st flagellomere 2.1-2.3× longer than wide. Tyloids on flagellomeres 7/8-20/22, long-oval, maximally 0.7-0.9× as long as their flagellomeres. Temple moderately and roundly narrowed behind eyes. OED 1.3× ocellar diameter. Frons and vertex densely punctate, punctures more scattered opposite lateral ocellus. Face densely punctate. Clypeus densely punctate basally, with scattered punctures apically. Gena with dense and coarse punctures. MI 0.4.

Mesosoma with pale brownish hairs. Mesoscutum with rather fine and dense, partly scattered punctures. Mesopleuron and metapleuron coarsely and densely punctate. Scutellum slightly longer than wide, with scattered punctures and lateral carina in anterior 0.2. Area superomedia halfmoon-shaped, slightly wider than long. Fore metatarsus without apical tooth. Hind femur 4.0-4.7× longer than wide. Postpetiolus distinctly widened; lateral field punctate, 0.6× as wide as median field; median field ± elevated, with coarse striae. Gastrocoelus strongly impressed. Thyridium slightly oblique, c. 1.0× as wide as the interval. 2 nd tergite 1.0× as long as wide. 2 nd to 4 th tergites coarse and densely punctate. 2 nd tergite coarsely and 3 rd tergite finely striate medially.

R e m a r k: The ♁♁ resemble Coelichneumon subviolaceiventris (PIC) and run to this species in the key of Westpalaearctic Coelichneumon species ( RIEDEL 2012: 1490-1496), but differ slightly by a longer 1 st flagellomere and malar space and by the entirely red hind femur.
