description: Heterospilus (Heterospilus) longiventrius sp. nov.
(Fig. 9)
Description. Female. Body length 4.6 mm; fore wing length 3.3 mm.
Head. Antennae slender, filiform, more than 22-segmented (apical segments missing). Scape 1.3 times as long as maximum width. First flagellar segment 5.0 times as long as its apical width, almost as long as second segment. Head behind eyes (dorsal view) distinctly and roundly narrowed. Width of head 1.1 times its median length. Eye 3.3 times as long as temple (dorsal view). Ocelli arranged in triangle with base 1.3 times its sides. POL: OD: OOL = 4: 3: 7. Vertex narrowly smooth medially, finely and distinctly transversely striate laterally. Frons very finely transversely striate. Vertex with sparse, short setae. Face smooth, its width 0.8 times height of eye, 1.2 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 1.8 times its height. Mesoscutum almost smooth, highly and perpendicularly elevated above pronotum, with dense setae arranged along notauli. Notauli shallow, sparsely and distinctly crenulate. Scutellum smooth. Prescutellar depression deep, rather long, smooth, with five 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 = 13: 11: 55. First discal cell 1.8 times as long as maximum width. 1-SR+M distinctly curved. m-cu postfurcal. Hind wing: M+CU: 1-M = 11: 14. m-cu weakly curved towards base of wing, antefurcal, pigmented.
Legs. Hind coxa almost smooth dorsally. Hind femur smooth, 3.75 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 1.3 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 2.5 times its minimum width, length equal to its maximum width. Suture between second and third tergites deep and distinctly sinuate. Second tergite entirely and densely striate, median length of tergite 0.5 times its basal width, 0.9 times length of third tergite. Third tergite in basal 0.4 with a distinct, wide, transverse furrow. Third tergite in subbasal 0.4 distinctly striate. Fourth tergite in basal 0.2 shortly striate. Fifth tergite shortly striate basally. Remaining tergites smooth. Ovipositor sheath 1.1 times as long as metasoma and 0.85 times as long as fore wing.
Colour. Head brownish yellow, vertex dark brown, pale around eyes. Mesosoma almost black, mesopleuron reddish brown in lower half. Metasoma dark brown. 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 3.9 mm; fore wing length 3.2 mm. Antennae 33-segmented. Mesosoma 1.9 times as long as its height. Fore wing 3.0 times as long as maximum width. First discal cell 1.9 times as long as maximum width. Hind femur 3.5 times as long as wide. Hind tarsus 1.1 times as long as hind tibia. Median length of second tergite 0.4 times its basal width
Male. Unknown.
Material examined. Holotype: Ƥ, China, Zhejiang Prov., Lin’an, Qingliangfeng, light trap, 8–12.VIII.2005, Shi Min, No. 200607306 (ZJUH). Paratype. 1Ƥ, China, Zhejiang Prov., Gutianshan, 2.VII.2005, Wu Qiong, No. 200615966 (ZJUH).
Diagnosis. This new species is similar to H. separatus Fischer, but differs in having the temple short, vertex finely striate at least laterally, fourth and fifth tergites shortly striate basally.
Etymology. From Latin “longus” meaning “long”, and “ventris” meaning “abdomen”.
Distribution. China (Zhejiang).
