Heterospilus (Heterospilus) nanlingensis sp. nov.

( Fig. 10 )

Description. Female. Body length 4.9 mm; fore wing length 3.75 mm.

Head. Antennae slender, filiform, 29-segmented. Scape 1.7 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width, 1.15 times as long as second segment. Penultimate segment 3.5 times longer than wide, 0.8 times as long as first flagellar segment, as long as apical segment. Head behind eyes (dorsal view) distinctly and roundly narrowed. Width of head 1.5 times its median length. Eye 1.8 times as long as temple (dorsal view). Ocelli arranged in almost equilateral triangle. POL: OD: OOL = 3: 3: 8. Vertex and frons entirely densely and distinctly transversely striate. Vertex widely with sparse, short setae. Face more or less coarsely striate, with rugulosity between striae, smooth on narrow median vertical area, its width 0.9 times height of eye, 1.1 times height of face and clypeus combined. Eye glabrous, 1.3 times as high as broad. Malar space 0.4 times height of eye, 0.9 times basal width of mandible. Malar suture absent. Occipital carina complete dorsally, fused with hypostomal carina ventrally.

Mesosoma. Length 1.9 times its height. Mesoscutum distinctly and densely granulate, with dense and fine transverse striation, with two distinct, weakly convergent posteriorly and undulate carinae, rugose between their in wide area in medioposterior 0.4, highly and perpendicularly elevated above pronotum, with sparse setae arranged along notauli. Notauli entirely wide and rather 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 large and 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 = 20: 8: 50. First discal cell 1.8 times as long as maximum width. 1- SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU 0.9 times as long as 1-M. m-cu almost straight, oblique towards base of wing, antefurcal, pigmented.

Legs. Hind coxa distinctly striate dorsally. Hind femur almost smooth, 3.5 times as long as wide. Hind tibia with short, dense setae dorsally; length of these setae 0.5–0.8 times maximum width of hind tibia. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.5 times as long as second-fifth segments combined; second tarsal segment 0.7 times as long as basitarsus, 1.6 times as long as fifth segment (except pretarsus).

Metasoma. Almost 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 2.0 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 tergite 0.6 times its basal width, 1.05 times length of third tergite. Third tergite in basal 0.3 with distinct, rather narrow, distinctly and short crenulate transverse furrow. Fourth tergite with very short striate basally. Remaining parts of tergites smooth. Ovipositor sheath 0.6 times as long as metasoma and 0.4 times as long as fore wing.

Colour. Head brownish yellow. Mesosoma reddish brown in anteriorly half, black in posteriorly half. Metasoma almost black, fifth-sixth tergites reddish brown. Antennae brownish yellow to black, two basal segments brownish yellow. Palpi pale yellow. Legs yellow, all coxae and trochanters pale yellow. Ovipositor sheath dark brown, paler basally. Wings faintly infuscate. Pterostigma dark brown.

Male. Unknown.

Material examined. Holotype: Ƥ, China, Guangdong Prov., Fuyuan, Nanling, 4.VIII.2004, Xu Zaifu, No. 20049728 ( ZJUH).

Diagnosis. This new species is similar to H. alboapicalis Belokobylskij , but differs in having the antenna apically dark, second tergite long, medioposterior sculptured area of mesoscutum large, and fifth tergite entirely smooth.

Etymology. From the name of the type locality of species.

Distribution. China (Guangdong).
