(Figs. 35–42)
Description. FEMALE. Body length 5.3 mm; fore wing length 3.7 mm. Head. Width 1.3 times its median length. Antennae slender, almost filiform, 29-segmented. Scapus 1.8 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width, almost equal to second segment. Penultimate segment 4.0 times as long as wide, 0.8 times as long as first segment, 0.9 times as long as apical segment. Head behind eyes almost roundly narrowed in dorsal view. Eye 2.0 times as long as temple in dorsal view. Ocelli medium-sized, in triangle with base almost equal to its sides. POL: OD: OOL=4: 2: 5. Temple almost smooth ventrally. Vertex transversely and weakly undulately striate, with very sparse, short setae. Frons rugulose with granulation. Eye glabrous, 1.3 times as high as broad. Malar space 0.2 times height of eye, 0.8 times as long as basal width of mandible. Face rugulose, partly with granulation, its width 1.2 times height of eye, 1.2 times height of face and clypeus combined. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 1.8 times as long as its height. Pronotal carina fine, widely separated medially from posterior margin of pronotum; distances from carina to anterior and posterior margins of pronotum subequal. Mesoscutum entirely densely and evenly pubescent, densely granulate, highly and roundly raised above pronotum; its median lobe without median depression. Notauli deep, complete, crenulate. Scutellum densely granulate. Prescutellar depression deep, with three carinae, smooth between carinae, 0.5 times as long as scutellum. Mesopleura almost smooth, rugose-striate in upper third. Precoxal sulcus deep, long, almost smooth, running along anterior 2/3 of lower part of mesopleuron, connected with prepectal carina. Prepectal carina distinct, wide ventrally, without widened lobes opposite to fore coxa. Propodeum with median carina in basal half, basolateral areas densely reticulate in posterior half and smooth basally; areola short and wide.
Wings. Fore wing 3.5 times as long as maximum width. Vein r arising slightly behind middle of pterostigma. 3- RS forming very obtuse angle with r. 3-RS: r: SR1= 18: 7: 38. Second submarginal cell large, 3.4 times as long as maximum width, 1.4 times as long as first subdiscal cell, almost equal to first discal cell. 1-SR+R distinctly Scurved. m-cu almost interstitial. 1-CU1 1.1 times as long as cu-a. CU1a arising from anterior 1/3 of distal margin of first subdiscal cell. Hind wing vein M+CU vein 0.7 times as long as 1-M vein; m-cu weakly curved, slightly antefurcal, pigmented.
Legs. Hind coxa rugulose dorsally. Hind femur striate dorsally, smooth at most part. Hind femur 3.8 times as long as wide, with distinct dorsal protuberance. Hind tibia with long, dense setae dorsally. Hind tarsus almost equal to hind tibia. Hind basitarsus equal to second–fifth segments combined; second tarsal segment 0.3 times as long as basitarsus, almost equal to fifth segment (except pretarsus).
Metasoma. Almost equal to mesosoma and head combined, with six visible tergites. First tergite entirely longitudinally striate, rugulose between striations, with distinct dorsal subparallel carinae, its width 2.2 times its minimum width; its length almost equal to its maximum width. Second tergite at most part (except apical area) longitudinally striate, rugulose between striation, without a basal area, with a rather distinct apical area, median length of second tergite (with apical area) 0.6 times as long as its basal width. Second suture deep and uniformly curved. Third–fifth tergites coarsely striate, smooth in apical 1/4. Sixth tergite weakly enlarged, with coarsely dense and concentric striation, weakly regularly round posteriorly, without median emargination. Ovipositor sheath 0.6 times as long as metasoma and 0.3 times as long as fore wing.
Colour. Body black. Antennae light reddish brown to black. Palpi pale yellow. Legs yellowish brown to light reddish brown; fore and middle coxae reddish brown, sometimes yellowish brown; hind coxa almost black; hind tibia black basally; all tarsi reddish brown, sometimes yellowish brown. Wings faintly infuscate. Pterostigma dark brown, paler basally and apically.
Male. Unknown.

(ZJUH).
Distribution. China (Yunnan, Hunan, Hainan, Guangdong).
Etymology. From Latin “ rugosus ” meaning “wrinkled”.
Diagnosis. This new species is similar to I. perakensis Belokobylskij, but differs in having the occipital carina fused with hypostomal carina, vein 1-SR+R of fore wing distinctly S-curved, second tergite rugulose between striation, and ovipositor sheath shorter.
