Heterospilus (Heterospilus) fujianensis sp. nov.

( Fig. 6 )

Description. Female. Body length 2.5 mm; fore wing length 1.7 mm.

Head. Antennae slender, filiform, 19-segmented. Scape 1.3 times as long as maximum width. First flagellar segment 5.4 times as long as its apical width, 0.9 times as long as second segment. Penultimate segment 5.5 times longer than wide, as long as first flagellar segment, as long as apical 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: 5. 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. Eye glabrous, 1.3 times as high as broad. Malar space 0.3 times height of eye, 0.7 times basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.

Mesosoma. Length 1.8 times its height. Mesoscutum finely coriaceous, 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 half of lower part of mesopleuron. Propodeum with distinctly delineated by carinae and long basolateral areas, with distinctly delineated areola, basal carina very short; basolateral areas almost smooth; remaining part of propodeum coarsely rugose-areolate.

Wings. Fore wing 2.9 times as long as maximum width. Vein r arising distinctly before middle of pterostigma. 3-SR forming very obtuse angle with r. 3-SR: r: SR1 = 5: 10: 32. First discal cell 1.5 times as long as maximum width. 1-SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 9: 8. m-cu weakly curved towards base of wing, antefurcal, pigmented.

Legs. Hind coxa smooth dorsally. Hind femur smooth, 3.5 times as long as wide. Hind tibia dorsally with short, rather dense and semi-erect setae; length of these setae 0.5–0.7 times maximum width of hind tibia. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.35 times as long as second-fifth segments combined; second tarsal segment 0.9 times as long as basitarsus, 1.5 times as long as fifth segment (except pretarsus).

Metasoma. Almost as long as mesosoma and head combined. First tergite with distinct convergent posteriorly dorsal carinae, densely and coarsely striate; apical width of tergite 2.0 times its minimum width, length 1.1 times its maximum width. Suture between second and third tergites almost straight. Second tergite entirely and densely striate, median length of second tergite 0.5 times as long as its basal width, 0.9 times as long as length of third tergite. Remaining tergites smooth. Ovipositor sheath 0.5 times as long as metasoma and 0.4 times as long as fore wing.

Colour. Body brownish yellow. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs brownish yellow, all trochanters pale yellow. Ovipositor sheath dark brown. Wings faintly infuscate. Pterostigma light brown.

Variation. Body dark brown. Body length 2.8 mm; fore wing length 1.8 mm. Scape 1.2 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width. Eye 2.0 times as long as temple (dorsal view). Mesoscutum sometimes distinctly coriaceous. Pterostigma brown. Body color sometimes darker.

Male. Unknown.

Material examined. Holotype: Ƥ, China, Fujian Prov., Wuyishan Tongmu, 15.IV.2009, Tan Jiangli, No. 200900131 ( ZJUH). Paratype. 1Ƥ, China, Jilin Prov.: Changbaishan, Lou Juxian, No. 976561 ( ZJUH).

Diagnosis. This new species is similar to H. ater Fischer , but differs in having the third and following tergites smooth, frons smooth, and first tergite narrow.

Etymology. From the name of province, holotype locality of species.

Distribution. China (Fujian, Jilin).
