Recognition. This species appears very similar to I. aktruensis sp. nov. on the basis of male terminalia, but is distinguished from the latter by a broader cercus and postgonite and shorter apical section of the phallus (Fig. 70).

Frons represented by small triangular space just above antennae, bare, greyish pollinose. Ocellar triangle prominent, with 2 pairs of long hair-like setae. Postvertical setae subequal in length with postocular setae, thin; occiput covered with numerous similar setae in lower part. Antenna dark brown; scape short, slightly shorter than globular pedicel, both with short setae; postpedicel broad, more than 4 times longer than basal width, base little expanded, only slightly tapered apically; stylus apparently very short, shorter than width, sensillum-tipped; segment 9 tubular, shorter than width, apical sensillum about as long as segment 9. Proboscis partially retracted in head, true length unknown, only apex of palpus visible. Thorax dark brown in ground-colour, including postpronotal lobe and postalar tubercle, with brown to black setation; scutum viewed dorsally entirely velvety brown, without vittae; mesopleuron uniformly greyish brown pruinose. Proepisternum with several long setae. Postpronotal lobe with 1 long thin and several shorter setae. Mesonotal setae distinct, thin; acr very short, biserial, lacking on prescutellar depression, distance between rows shorter than length of ...
