Ipodoryctes wuyiensis Tang & Chen , sp. nov.

( Figs. 50–58 )

Description. FEMALE. Body length 4.1 mm; fore wing length 3.5 mm. Head. Width 1.4 times its median length. Antennae slender, almost filiform, 38-segmented. Scapus 1.4 times as long as maximum width. First flagellar segment 4.0 times as long as its apical width, almost as long as 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 roundly narrowed in dorsal view. Eye 2.1 times as long as temple in dorsal view. Ocelli medium-sized, in triangle with base 1.6 times its sides. POL: OD: OOL= 5: 3: 6. Temple smooth. Vertex smooth, with very sparse, short setae. Frons finely transversely striate. Eye glabrous, 1.3 times as high as broad. Malar space 0.3 times height of eye, 0.6 times basal width of mandible. Face rugulose-striate, its width almost equal to height of eye, 1.3 times height of face and clypeus combined. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally. Mesosoma. Length 1.9 times 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 ground granulation, with three subparallel carinae medioposterior, highly and roundly raised above pronotum; its median lobe without median depression. Notauli deep, complete, crenulate. Scutellum almost smooth. Prescutellar depression deep, with three carinae, smooth between carinae, 0.5 times as long as scutellum. Mesopleura smooth, striate in upper third. Precoxal sulcus shallow, 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 half; basolateral areas distinctly marginate, almost smooth; areola distinct marginate.

Wings. Fore wing 4.0 times as long as maximum width. Vein r almost arising from the middle of pterostigma. 3-RS forming very obtuse angle with r. 3-RS: r: SR1= 10: 30: 48. Second submarginal cell long, 3.7 times as long as maximum width, 2.3 times as long as first subdiscal cell, 1.5 times as long as first discal cell. 1-SR+R distinctly S-curved. m-cu interstitial. 1-CU1 1.5 times as long as cu-a. CU1a arising from anterior 1/3 of distal margin of first subdiscal cell. Hind wing vein M+CU 0.8 times as long as vein 1-M. m-cu weakly curved, interstitial, pigmented.

Legs. Hind coxa striate dorsally. Hind femur striate dorsally, 3.1 times as long as wide, with distinct dorsal protuberance. Hind tibia with dense, rather long setae dorsally. Hind tarsus almost equal to hind tibia. Hind basitarsus 0.8 times as long as second-fifth segments combined; second tarsal segment 0.4 times as long as basitarsus, 1.5 times as long as fifth segment (except pretarsus).

Metasoma. 1.4 times as long as mesosoma and head combined, with six visible tergites. First tergite entirely longitudinally striate, with distinct dorsal carinae, its apical width of first tergite 2.0 times its minimum width; its length almost equal to its maximum width. Second tergite almost striate, without a distinct basal area, with a small distinct apical area and smooth in its anterior half, median length of second tergite (with apical area) 0.7 times its basal width. Second suture deep and uniformly curved. Third–fifth tergites longitudinally striate and without additional rugosity, widely smooth apically. Sixth tergite densely and concentrically striate, moderately large, round on posterior margin, without median emargination. Ovipositor sheath 1.5 times as long as metasoma and 1.1 times as long as fore wing.

Colour. Body black, abdomen reddish apically and laterally. Antennae reddish brown to black, two basal segments reddish brown. Palpi pale yellow. Legs light brown; hind coxa reddish brown; hind femur brown. Wings faintly infuscate. Pterostigma dark brown, lighter basally and apically.

Male. Unknown.

Material examined. Holotype. Ƥ, China, Fujian Prov., Wuyishan (27°42ʹN, 117°45ʹE), 22–25.VIII.2007, Xie Cuihong, No. 200807234 ( ZJUH).

Distribution. China (Fujian).

Etymology. From the mountain Wuyishan, type locality of the species.

Diagnosis. This new species is similar to I. elegans Belokobylskij , but differs in having the occipital carina fused below with hypostomal carina, distances from carina to posterior margin of pronotum 0.7 times distance from carina to anterior margin, and hind wing vein m-cu interstitial.
