Heterospilus (Heterospilus) qingliangensis sp. nov.

( Fig. 14 )

Description. Female. Body length 3.15 mm; fore wing length 2.6 mm.

Head. Antennae slender, filiform, more than 25-segmented (apical segments missing). Scape 1.2 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width, 0.9 times as long as second segment. Head behind eyes (dorsal view) distinctly and roundly narrowed. Width of head 1.4 times its median length. Eye 2.2 times as long as temple (dorsal view). Ocelli arranged in almost equilateral triangle. POL: OD: OOL = 2: 2: 7. Vertex and frons smooth. Vertex with sparse, short setae. Face smooth, its width equal to height of eye, 1.3 times height of face and clypeus combined. Malar space 0.4 times height of eye, 1.2 times basal width of mandible. Eye glabrous, 1.2 times as high as broad. Malar suture absent. Occipital carina complete dorsally, not fused with hypostomal carina ventrally.

Mesosoma. Length 1.8 times its height. Mesoscutum almost smooth, highly and perpendicularly elevated above pronotum, with very sparse setae arranged along notauli. Notauli shallow, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with three distinct carinae, 0.4 times as long as scutellum. Subalar depression rather wide, coarsely rugose-striate. Precoxal sulcus deep, smooth, running along anterior 0.7 of lower part of mesopleuron. Propodeum with distinctly delineated by carinae and long basolateral areas, with distinctly delineated areola, basal carina short; basolateral areas almost smooth and distinctly rugulosereticulate along carinae; remaining part of propodeum coarsely rugose-areolate.

Wings. Fore wing 3.1 times as long as maximum width. Vein r arising almost from middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 12: 7: 57. First discal cell 1.7 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU 0.8 times as long as 1-M. m-cu weakly curved towards base of wing, antefurcal, pigmented.

Legs. Hind coxa distinctly smooth. Hind femur finely striate dorsally, 4.4 times as long as wide. Hind tibia with short, dense setae dorsally; length of these setae 0.5–0.7 times maximum width of hind tibia. Hind tarsus 1.15 times as long as hind tibia. Hind basitarsus 0.5 times as long as second-fifth segments combined; second tarsal segment 0.75 times as long as basitarsus, 1.7 times as long as fifth segment (except pretarsus).

Metasoma. Almost 1.1 times as long as mesosoma and head combined. First tergite with more or less distinct, weakly and curvedly convergent posteriorly dorsal carinae, densely and coarsely striate; apical width of tergite 2.4 times its minimum width, length almost equal to its maximum width. Suture between second and third tergites almost straight. Second tergite entirely and densely striate, median length of tergite 0.6 times its basal width, equal to length of third tergite. Third tergite in basal 0.2 with distinct, wide, transverse furrow, distinctly striate in basal 0.4. Fourth tergite in basal 0.2 shortly striate. Fifth tergite shortly striate basally. Remaining parts of tergites smooth. Ovipositor sheath 1.4 times as long as metasoma and 0.85 times as long as fore wing.

Colour. Head brownish yellow. Mesosoma dark brownish yellow. Metasoma dark brown, third and fourth tergites dark brownish yellow in basal half, brownish yellow in apical half. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs yellow. Ovipositor sheath dark brown, paler basally. Wings faintly infuscate. Pterostigma dark brown.

Variation. Body length 2.9–4.2 mm; fore wing length 2.0– 3.1 mm. Antennae 24-segmented. Scape 1.3 times as long as maximum width. Mesosoma 1.9–2.0 times as long as height. Fore wing 2.7–2.8 times as long as maximum width. Hind femur 4.2–4.3 times as long as wide.

Male. Unknown.

Material examined. Holotype: Ƥ, China, Zhejiang Prov., Lin’an, Qingliangfeng, 12.VIII.2005, Shi Min, No. 200607640 ( ZJUH). Paratypes. China, Zhejiang Prov.: 1Ƥ, same locality as holotype, 8.VIII.2005, Shi Min, No. 200607072 ( ZJUH); 1Ƥ, same locality as holotype, 9.VIII.2005, Zhang Hongying, No. 200607120 ( ZJUH); 2Ƥ, same locality as holotype, 10.VIII.2005, Shi Min, Nos. 200607380, 200607398 ( ZJUH); 1Ƥ, same locality as holotype, 11.VIII.2005, Zhang Hongying, No. 200607489 ( ZISP); 1Ƥ, same locality and date as holotype, Zhang Hongying, No. 200607750 ( ZJUH).

Diagnosis. This new species is similar to H. cephi Rohwer , but differs in having the head smooth, occipital carina not fused with hypostomal carina ventrally, mesoscutum smooth, basolateral areas of propodeum almost smooth, hind coxa entirely smooth, and ovipositor sheath long. H. qingliangensis sp. nov. also resembles H. separatus Fischer , but differs in having the basal sculpture on fourth and fifth tergites, hind femur and hind tibia slender, pterostigma pale, first tergite short, and colouration of body pale.

Etymology. From the name of type locality of species.

Distribution. China (Zhejiang).
