(Figs. 10–18)
Description. FEMALE. Body length 3.3 mm; fore wing length 3.0 mm. Head. Width 1.3 times its median length. Antennae slender, almost filiform, 30-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, almost equal to apical segment. Head behind eyes almost roundly narrowed in dorsal view. Eye 2.3 times as long as temple in dorsal view. Ocelli medium-sized, in triangle with base almost equal to its sides. POL: OD: OOL=3: 3: 6. Temple almost smooth ventrally. Vertex transversely striate, with very sparse, short setae. Frons coarsely and obliquely striate. Eye glabrous, 1.5 times as high as broad. Face rugulose-striate, partly with granulation, its width 1.2 times height of eye, 1.3 times height of face and clypeus combined. Malar space 0.2 times height of eye, 0.6 times as long as basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 2.1 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 shallow posteriorly, complete, crenulate. Scutellum densely granulate. Prescutellar depression deep, with three carinae, smooth between carinae, 0.4 times as long as scutellum. Mesopleura almost smooth, coriaceous with some rugosity-striation 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 distinctly marginate, almost smooth; areola distinct marginate 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= 24: 6: 45. Second submarginal cell large, 3.6 times as long as maximum width, 1.5 times as long as first subdiscal cell, almost equal to first discal cell. 1-SR+R slightly Scurved. m-cu slightly postfurcal. 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 0.7 times as long as vein 1-M. m-cu weakly curved, distinctly antefurcal, pigmented.
Legs. Hind coxa rugulose-granulate dorsally. Hind femur striate dorsally, smooth at most part, 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 1.1 times as long as 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 coarsely striate, its apical width of first tergite 2.1 times its minimum width; its length almost 1.5 times as long as its maximum width. Second tergite mostly coarsely striate, without a basal area, with a rather distinct, smooth 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 1.5 times as long as metasoma and 1.6 times as long as fore wing.
Colour. Body black. Antennae light reddish brown to black. Palpi pale yellow. Legs yellowlish brown to light reddish brown; hind coxa black; hind tibia black basally; all tarsi reddish brown. Wings faintly infuscate. Pterostigma dark brown, paler basally and apically.
Male. Unknown.
Material examined. Holotype. Ƥ, China, Guizhou Prov., Mayanghe, Wanjia (28°39ʹN, 108°17ʹE), 1- 3.X.2007, Zhu Lanlan, No. 200709295 (ZJUH).
Distribution. China (Guizhou).
Etymology. From the Guizhou province, type locality of the species.
Diagnosis. This new species is similar to I. andreii Belokobylskij, but differs in having the antennae shorter, precoxal sulcus running along anterior 2/3 of lower part of mesopleuron, frons coarsely and obliquely striate, mesopleura coriaceous with some rugosity-striation in upper third, and first and second tergites not rugulose between striations.
