Supplementary description. Male. Structure ( Figs 29–32 ). Metope with distinct median carina running from its upper margin to metopoclypeal suture which is in shape of deep hollow ( Fig. 31 ). Sublateal carinae of metope well visible only in its upper part and above clypeus. Coryphe nearly square, with weak median carina; anterior margin angularly convex (at the corner of nearly 100°); posterior margin angularly concave ( Figs 29, 32 ). Lateral margins of coryphe weakly diverging above pronotum. Ocelli absent. Pedicell barrel-shaped. Pronotum nearly equal in length to coryphe at midline, pressed in the middle; anterior margin strongly convex; posterior margin straight. Paradiscal fields of pronotum wide. Paranotal lobes large, without carinae. Mesonotum 1.3 times as long as pronotum at midline, with median and lateral carinae. Forewing sequences: R 2, furcating near to basal cell; M 2, CuA 2, both furcating near to wing middle ( Fig. 30 ). Hind tibia with 2 lateral spines in its apical half and with 8–10 apical spines. First metatarsomere 1.5 times as long as second one, with 2 latero-apical and 7 intermediate spines.

Male. Coloration ( Figs 29–32 ). Metope yellowish light brown to dark brown between sublateral carinae and dark brown to black between lateral margins and sublateral carinae, with light yellow transverse carina and pustules (traces of larval sensory pits). Metope with black band above transverse carina. Preocular fields and genae yellowish light brown. Each preocular field with dark brown spot below coryphe margin. Postocular fields dark brown. Postclypeus brown frontally and yellowish light brown under metopoclypeal suture and laterally. Anteclypeus brown frontally and yellowish light brown laterally. Scapus yellow. Pedicel brown, with yellow apex. Rostrum yellowish or greenish light brown, with black apex. Coryphe and middle of pronotum and mesonotum greenish light brown. Paradiscal fields of pronotum and nearby areas of paranotal lobes dark brown to black, with greenish light yellow pustules. Lower margin of paranotal lobes at the level of costal margin of fore wing whitish. Fore wings greenish light brown (in freshly caught specimens), with dark brown to black veins; each wing sometimes with black spot between second radius vein and first median vein at the level of apex of clavus. Hind wings dark brown. Legs light brown greenish. Fore and middle femora and tibiae with brown crossbands. Hind femora dark brown dorsally. Tarsi sometimes green, with dark brown apices of third tarsomeres and claws. Leg spines dark brown to black.Abdominal sternites greenish light yellow, with dark brown middle parts on IV–VII ones in some specimens. Styles with dark brown to black margins in some specimens. Anal tube greenish light yellow.

Female. Structure ( Figs 33–37 ). As male except fore wing with wave-shaped radius veins and first radius vein with reticulate venation apically ( Fig. 34 ).

Female. Coloration ( Figs 33-37 ). General coloration yellowish brown. Metope dark brown to black above trasverse carina and between lateral margins and sublateral carinae in its upper part ( Fig. 35 ). Pustules of metope yellowish light brown. Sometimes metope dark brown, except yellowish carinae and pustules. Postclypeus sometimes dark brown, except yellowish band below metopoclypeal suture.Anteclypeus sometimes dark brown. Preocular fields and genae yellowish. Scapus yellow. Pedicel dark brown, with yellow apex. Rostrum brown dorsally and yellowish brown ventrally, with black apex. Paradiscal fields of pronotum dark brown to black, with yellowish light brown pustules ( Figs 33, 37 ). Paranotal lobes brown to dark brown, with yellowish light brown pustules, except lower margin. Fore wings with dark brown transverse veins, sometimes with two wide black crossbands basally and near to clavus ( Fig. 37 ). Hind wings greyish brown. Hind coxae yellowish, with dark brown to black areas. Femora brown to dark brown dorsally. Apices of hind femora sometimes greenish. Tibiae sometimes with dark brown areas. Tarsi greenish, with dark brown claws and spines. Abdominal sternites yellowish, except sternites V–VII with dark brown areas medially. Laterotergites dark brown. Anal tube and gonocoxae yellowish ( Fig. 36 ). Gonoplacs yellowish light brown, with dark brown margins.

Male genitalia ( Figs 16–25 ). Very close to I. coleoptratus described above. Anal tube nearly twice as long as wide, apex without concavity in dorsal view ( Fig. 21 ); lateral margins not turned down (in lateral view) ( Fig. 22 ). Anal column short. Pygofer with widely convex hind margins in lateral view ( Fig. 25 ). Phallobase horseshoe shaped in lateral view, with weak two-lobed median carina (mc) ( Fig. 16 ). Processes of inner walls of dorsolateral lobes of phallobase large, each with semicircular lobe ( Fig. 24 ). Projections of ventral margins of dorsolateral lobes of phallobase covering aedeagal hooks large, nearly square ( Fig. 17 ). Ventral phallobase lobe wide and long, with two lateral processes apically ( Fig. 16 ). Apical aedeagal processes long and wide (in lateral view), weakly narrowing to rounded apices, slightly surpassing upper phallobase margin, each with short and rounded subapical projection ( Figs 17, 18 ). Ventral hooks of aedeagus 0.3 times as long as aedeagus, acuminate apically and directed downwards. Connective with wide cup-like apodeme ( Fig. 23 ). Style with nearly straight hind margin, caudo-dorsal angle widely rounded ( Fig. 19 ). Capitulum of style on wide neck in lateral view, wide and not narrowing apically in dorsal view, with wide lateral tooth ( Fig. 20 ).

Female genitalia ( Figs 26–28 , 36 ). Sternum VII with deeply concave hind margin ( Figs 28 , 36 ). Anal tube nearly twice as long as wide, slightly narrowing apically in dorsal view ( Fig. 26 ). Anal column (paraproct) short. Gonoplacs convex. Each gonocoxa VIII with large rounded lobe ( Fig. 27 ).

Total length. Males— 5.1–5.9 mm. Females—5.2–6.0 mm.
