Original description sensu Kotenko (2007) (translated from Russian and with updated morphological terminology and comments in brackets when our observations did not match Kotenko’s)

[Diagnosis: Similar to I. kostjuki , but differs in the following characters:] T2 wider, width ~3 × central length. T2 1.5× shorter than T3, posterior margin weakly arcuately curved. Ovipositor sheaths shorter, about 0.5× metatibia length. Pterostigma uniformly colored, dark brown. Fore wing vein R1 2.3–2.5 × longer than the distance from it to apex of 3 RS. Anteromesoscutum with less noticeable setae and denser punctation, mostly matte, posteriorly with smooth sheen. Smaller: 2.5 [mm].

Head 1.7× as wide as long, slightly narrower than mesosoma width, roundly narrowed behind eyes. Gena 1.5 × shorter than the eye width (laterally). Ocelli in obtuse triangle [ocelli in low triangle], its base 1.9– 2.0× as long as OOL [POL 1.2× OOL]. POL 1.4× greater than OD [POL 2.2× OD]. Tangent to anterior edge of the posterior ocelli crossing posterior edge of the front ocellus [imaginary tangent posterior to the anterior ocellus touches the posterior ocelli]. Eyes noticeably converging downwards, their longitudinal diameter 1.7 × the transverse diameter and 1.6× the height of the face. Upper width of face 1.2 × more than the lower width, and 1.6× its height. Front margin of the clypeus convex, its height 3.2× less than face height. Gena height 3.7× shorter than longitudinal eye diameter. Antenna slightly longer than body, F15 length 1.3× its width. Mesosoma barely shorter than metasoma. Mesosoma length 1.6× more than its height. Fore wing 1.2× as long as hind wing, and slightly shorter than body. Pterostigma 2.6× as long as wide, slightly shorter than vein R1. Vein r slightly shorter than 2 RS. Vein 1cu-a arising at around middle of the 1st discal cell length; hind wing vein cu-a almost straight; metafemur length 3.2–3.3 × its width and 1.3× less than the length of the metatibia. Metatarsus 1.2× as long as metatibia, Ratio of holotype metatarsomere lengths as follows 3.5:1.9:1.4:1.0:1.2. T1 slightly widened posteriorly, 1.3 × longer than maximum width.

Sculpture. Head dorsally, clypeus and frontal part of gena (narrow stripe behind eyes) with sparser punctures, more or less shiny. Face and posterior side of gena densely punctured, matte. Scutoscutellar suture narrow, crenulated. Scutellum with punctation less dense than mesoscutum, shiny. Propodeum, T1, T2 densely and softly wrinkled (except for posterior part of propodeum), matte. Metacoxa densely punctated apically, matte, their outer side more sparsely punctured, with satin sheen.

Coloration. Body black. Antennae almost black. Palps and tibial spurs yellowish. Tegulae, R1 and most veins in the middle of the fore wing dark brown. Wings slightly smoky. Legs mostly black. Apices of the front and middle femorae and all of tibiae reddish-brown, apex of metatibia and all tarsi slightly darkened.
