Type material

Holotype

KAZAKHSTAN – [Aktobe Region] • ♀; Aktyubinsk Province , Mugodzhary , 25 km north of the settlement Borly, locality of Baymen; [ 49.44° N, 58.90° E]; 13 Jun. 1985; A. Kotenko leg.; SIZK. GoogleMaps

Species concept

Our species concept is based on our examination of photos of the holotype and the information available in Kotenko (2004, 2007). In addition, the species is morphologically very distinct and unlikely to be confused. → ***.

Ecology / host information

Host unknown.

Distribution

PAL: Kazakhstan, Russia (SAR).

Molecular data

No molecular data available.

Remarks

In addition to the holotype, there are at least 5 female paratypes stored at SIZK ( Zerova et al. 2006).

Original description sensu Kotenko (2004) (translated from Russian and with updated morphological terminology and comments in brackets when our observations did not match Kotenko’s)

Diagnosis. The new species is close to I. urgo , from which it differs in having a matte anteromesoscutum, the smooth band posterior to the scutellum interrupted in the middle by a wrinkled area, smooth posterolateral part of scutellum, darkly colored legs, black or dark reddish-brown metacoxa, comparatively more long and narrow T1, and ovipositor almost as long as metatibia [ovipositor and sheaths appearing shorter than metatibia in holotype photos].

Description. Female. Body length 2.3–2.5 mm. Width of head twice its length [dorsal head width and length], slightly greater than width of anteromesoscutum; head roundly narrowed behind eyes. Ocelli in strongly obtuse triangle [ocelli in high triangle]; tangent to anterior margin of posterior ocelli running along posterior margin of anterior ocellus [imaginary tangent posterior to the anterior ocellus does not touch or cross the posterior ocelli]; POL distinctly greater than OD. Eyes strongly converging downwards, their transverse diameter 1.6 × less than longitudinal diameter and almost twice as long as gena width laterally. Face height with the clypeus slightly more than lower face width. Clypeus shortened, slightly incised along anterior margin, almost straight. Antennae shorter than body; length of F15 around 1.3× its width. Mesosoma noticeably shorter than metasoma, its length 1.5 × its height. Fore wing equal to or slightly shorter than body; length of pterostigma 2.4× its width; vein R1 slightly shorter than pterostigma and only slightly longer than distance from its apex to wing apex; vein 1cu-a arising at around middle length of 1st discal cell [vein 1cu-a arising at around basal third of length of 1st discal cell]; hind wing vein cu-a nearly straight. Metatibia noticeably shorter than metatarsus; inner spur of metatibia only slightly longer than outer spur, distinctly shorter than half length of basitarsus; Ratio of metatarsomere lengths as follows 4.3:2.1: 1.4: 1.0:1.3. T1 long and narrow, distinctly narrowed towards apex in posterior (sculpted) part, its length almost twice its maximum width; T2 comparatively large and wide. Ovipositor sheaths equal or slightly shorter than metatibia [ovipositor and sheaths appearing shorter than metatibia in holotype photos].

Sculpture. Face, gena, head dorsally, mesoscutum and scutellum with dense punctures, matte or with slight satin shine. Propodeum weakly sculptured, shining [sculptured, with smooth, shining area anteriormedially]. Basal half of T1 almost smooth and shining, its apical half and most of T2 with identical dense sculpture, with satin sheen; tubercle at base of median field of T2 with smoothed sculpture, shining.

Coloration. Body black, often metasoma (except T1 and T2) dark reddish-brown; antennal flagellomeres black or dark reddish-brown; visible mouthparts, clypeus, scapes and usually pedicels, tegulae, fore and often middle legs light-colored, yellowish-brown or brown; metacoxae black, rarely dark reddish-brown; metafemur brown or dark brown; metatibia brown with darkened apical third [metatibia light/yellowbrownish with darker apical third]; metatibial spurs whitish. Wings slightly milky; pterostigma brown, in basal half and usually along the anterior margin light; vein R1and veins in middle part of fore wing brown.

The male is unknown.
