TYPE MATERIAL. Holotype: ♀, Russia: Amur Province, KhR, 24 km W Arkhara, сordon Kleshinskoe ozero, forest, 12–14.VIII.2022 ( OK) ( ZISP).

DESCRIPTION. Female (holotype). Length 1.77 mm.

Colour. Body orange-yellow with areas around ocellus, occiput, pronotum anteriorly, spot on anterior margin of mid lobe of mesoscutum, spot on the middle of scutellum, median area of propodeum, the middle of gaster and ovipositor sheaths brownish black. Antenna yellowish brown. Legs pale yellow, all tarsi with last segments dark brown.

Sculpture. Mesosoma reticulate to reticulate-imbricate anteriorly; head, pronotum and axillae finely reticulate, dorsellum almost smooth; propodeum weakly reticulate to partly smooth ( Fig. 2 F ).

Head. 2.25 × as broad as long in dorsal view. POL 1.57 × OOL, OOL 1.75 × OD. Malar space 0.67 × height of eye. Antenna inserted near lower level of eyes; scape reaching lower margin of median ocellus; pedicel plus flagellum about 1.10 × as breadth of head; F1 1.80 × as long as pedicel, 1.25 × as long as broad; F2 thicker than F1, 1.15 × as long as broad; clava about as long as F1 plus F2, 2.43 × as long as broad.

Mesosoma. 1.65 × as long as broad (dorsal view). Pronotum medially 0.33 × as long as mesoscutum. Mesoscutum transverse, 1.83 × as broad as long, as long as scutellum. Scutellum flat, obvious rounded, sublateral lines absent; second pairs of setae situated near posterior margin of scutellum. Dorsellum 2.67 × as long as broad. Propodeum medially 1.60 × as long as dorsellum, with distinct median carina, plicae absent; callus with eight hairs. Legs slender, hind tibia spur about half length of basitarsus. Fore wing 2.19 × as long as broad; costal cell about as long as M; SM dorsally with 5 setae; M 4 ×length of ST; PM 0.89 ×length of ST and 0.24 × length of M; basal cell apically with 6 setae; speculum narrow, reaching to base of M, closed below ( Fig. 2H ). Hind wing 5.0 × as long as broad, almost rounded at apex.

Metasoma. Gaster ovate, slightly pointed, 1.88 × as long as broad, 1.30 × as long as mesosoma, 0.96 × as long as head plus mesosoma. Ovipositor sheath projecting beyond apex of last tergite.

Male. Unknown.

DIFFERENTIAL DIAGNOSIS. Cirrospilus kochetkovi sp. n. is similar to C. tischeriae Kamijo, 1992 by the scutellum without sublateral grooves lines ( Fig. 2E ), propodeum with median carina, plicae absent ( Fig. 2F ), antenna inserted near the lower eye orbit; scape reaching lower edge of median ocellus ( Fig. 2C ). The new species differs from C. tischeriae in having sculpture of mesoscutum not strongly raised-reticulate ( Figs 2D, E ) (strongly raised reticulate in C. tischeriae [ Kamijo, 1992: P. 392]); mid lobe mesoscutum with two pairs of pale bristles ( Fig. 2E ) (blackish bristles in C. tischeriae [ Kamijo, 1992: P. 392]), F1 1.8 × as long as pedicel and F2 1.3 × as long as broad ( Fig. 2G ) (F1 slightly to distinctly longer than pedicel, F2 almost quadrate in C. tischeriae [ Kamijo, 1992: P. 391–392]), speculum narrow ( Fig. 2H ) (speculum large in C. tischeriae [ Kamijo, 1992: P. 392]).

DISTRIBUTION. Amur Province. HOSTS. Unknown ETYMOLOGY. This species is named in honor to Denis N. Kochetkov (Khingan State Nature Reserve, Arkhara), a Russian hymenopterologist and expert for the Vespomorpha, who kindly organized our work in the Khingan Reserve.
