(Figs. 27–34)
Description. FEMALE Body length 3.0 mm; fore wing length 2.7 mm. Head. Width 1.4 times its median length. Antennae slender, almost filiform, 27-segmented. Scapus 1.5 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, equal to apical segment. Head behind eyes almost linearly narrowed in dorsal view. Eye 3.0 times as long as temple in dorsal view. Ocelli medium-sized, in triangle with base almost equal to its sides. POL: OD: OOL= 3: 2: 6. Temple rugulose-striate ventrally. Vertex distinct, dense, weakly undulate striate, with ground sculpture between striation, with very sparse, short setae. Frons rugulose. Eye glabrous, 1.3 times as high as broad. Face rugose-striate, its width almost equal to height of eye, 1.3 times height of face and clypeus combined. Malar space 0.2 times height of eye, 0.8 times as long as basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.
Mesosoma. Length 1.8 as long as its height. Pronotal carina fine, distinctly separated from posterior margin of pronotum; distances from carina to posterior margin of pronotum 0.7 times distance from carina to anterior margin. Mesoscutum entirely densely and evenly pubescent, densely rugulose-striate, with fine and dense granulation, highly and roundly raised above pronotum; its median lobe without median depression. Notauli rather shallow, complete, crenulate. Scutellum densely granulate. Prescutellar depression deep, with three carinae, smooth between carinae, 0.5 times as long as scutellum. Mesopleura almost smooth, longitudinally striate in upper third. Precoxal sulcus deep, long, almost smooth, running along entire 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 1/3; basolateral areas densely reticulate in posterior half and smooth basally; areola distinct marginate and wide.
Wings. Fore wing 3.5 times as long as maximum width. Vein r arising from middle of pterostigma. 3-RS forming very obtuse angle with r. 3-RS: r: SR1= 17: 8: 42. Second submarginal cell large, 2.3 times as long as maximum width, 1.1 times as long as first subdiscal cell, 0.8 times as long as first discal cell. 1-SR+R distinctly S-curved. mcu 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 vein 1-M. m-cu weakly curved, antefurcal, pigmented.
Legs. Hind coxa rugose-striate dorsally, finely punctulate ventrally. Hind femur finely striate dorsally, 3.9 times as long as wide, with distinct dorsal protuberance. Hind tibia with rather long, dense setae dorsally. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.9 times as long as second–fifth segments combined; second tarsal segment 0.3 times as long as basitarsus, 1.1 times as long as fifth segment (except pretarsus).
Metasoma. Almost equal to mesosoma and head combined, with six visible tergites. First tergite entirely longitudinally striate, with distinct and subparallel dorsal carinae, apical width of first tergite 1.7 times its minimum width; its length almost equal to its maximum width. Second tergite entirely longitudinally striate, without basal and apical areas, median length of second tergite 0.7 times as long as its basal width. Second suture deep and wide. Third–fifth tergites in basal 2/3–3/4 longitudinally striate, remainder smooth. Sixth tergite weakly enlarged, entirely semicircularly striate, almost straight in posterior margin, without median emargination. Ovipositor sheath 0.6 times as long as metasoma and 0.4 times as long as fore wing.
Colour. Body black. Antennae light reddish brown to black. Palpi pale yellow. Legs yellow, hind coxae reddish brown. Wings faintly infuscate. Pterostigma entirely yellow.
Male. Unknown.
Material examined. Holotype. Ƥ, China, Hainan Prov., Jianfengling (18°42ʹN, 108°50ʹE), 7.VI. 2007, Liu Jingxian, No. 200702365 (ZJUH).
Distribution. China (Hainan).
Etymology. This species is named in honour of Dr Liu Jingxian, the collector of this species.
Diagnosis. This new species is similar to I. brevitergum Belokobylskij, but differs in having the first flagellar segment of antennae long, pterostigma entirely yellow, and hind coxae reddish brown.
