Introduction Sinophorus Förster, 1869 belongs to the subfamily Campopleginae (Hymenoptera: Ichneumoni- dae) and comprises 113 species (Yu et al., 2012), of which 46 are from Palaearctic region (one species is also known from the Afrotropical region, and eight species from Oriental region), ten from Oriental re- gion (one is also known in the Palaearctic and Afrotropical regions), one is the Afrotropical, and 63 occur in the Nearctic region (three are also distributed in the Palaearctic region). Eight species were known from China hitherto (Sheng, Sun, 2010; Yu et al., 2012). Status of the genus was discussed by Townes (1970), Sanborne (1984) and Sheng and Sun (2010). Sanborne revised and keyed the world fauna of Sinophorus (Sanborne, 1984), provided a supplement to this revision (Sanborne, 1986), and later described a new species from Taiwan (Sanborne, 1990). Sino- phorus fuscicarpus (Thomson, 1887) is known as parasitoid of Dioryctria rubella Hampson (Lepidoptera: Pyralidae), and its biology was reported by Sun with co-authors (2006) and Sheng and Sun (2010). One Japanese species parasitizing Amphipoea spp. (Lepidoptera: Noctuidae) was described by Kusigemati (1993). Material and methods Specimens were collected with intercept traps (IT) (Li et al., 2012) in the forests of Shuangjiang Forest farm, Ji’an County, and Quannan County, Jiangxi Province of China. Forest of Shuangjiang Forest 133 farm is composed of mixed deciduous angiosperms and evergreen conifers, mainly Pinus massoniana (Lamb.), Quercus spp. and Cinnamomum spp. Forest of Quannan is composed of mixed deciduous angio- sperms and evergreen conifers, mainly Quercus spp., Castania spp., Castanopsis fabri Hance, Cinnamo- mum spp. and Pinus massoniana (Lamb.). Image of whole insect (Fig. 1) was taken using a Canon Power Shot A650 IS. Other images were taken using a Cool SNAP 3CCD attached to a Zeiss Discovery V8 Stereomicroscope and captured with QCapture Pro version 5.1. Type specimens are deposited in the Insect Museum, General Station of Forest Pest Management, State Forestry Administration, People’s Republic of China. Taxonomic part Sinophorus Förster, 1869 Sinophorus Förster, 1869: 153. Type species: (Limneria canarsiae Ashmead, 1898) = Mesoleptus? validus Cresson, 1864. Diagnosis. Propodeum with area superomedia completely fused with area petiolaris and forming a broad median longitudinal trough. Apex of propodeum not reaching middle of hind coxa. Fore wing with areolet present. Basal half of first metasomal segment more or less prismatic, the suture separating tergite from sternite a little below the mid-height. Ovipositor sheath approximately 3.0 times as long as apical height of metasoma. In Sanborne’s (1984: 63) key to species, the new species can be inserted as follows: 10a. Ovipositor 2.5–2.7 times as long as hind femur, with an unusually small dorsal notch. Median longi- tudinal carina of propodeum not distinctly indented at junction with basal transverse carina. Hind wing with nervellus usually intercepted. Holarctic ..............................................S. nitidus (Brischke) 10b Ovipositor 2.1–2.3 times as long as hind femur, with dorsal notch of normal size. Median longitudi- nal carina of propodeum (Fig. 107) often distinctly indented near junction with basal transverse ca- rina. Hind wing with nervellus usually not intercepted. Sweden ............................S. tibialis Sanborne 10c Ovipositor 2.0–2.1 times as long as hind femur, dorsal notch small, sharp. Median longitudinal carina of propodeum not distinctly indented at junction with basal transverse carina. Hind wing with nervel- lus intercepted. Oriental.....................................................................................S. impunctatus sp. n. In Sanborne’s (1990: 110) key to species, the new species can be inserted as follows: 38a(37a). Ovipositor strongly upcurving (Fig. 156), with height at mid-length less than width of hind basitarsus. Hind femur 4.4–4.6 times as long as high. China, Mongolia, Japan..................................... .......................................................................................................................S. exartemae (Uchida) 38b. Ovipositor moderately upcurving (Fig. 155), with height at mid-length equal to width of hind basi- tarsus. Hind femur 4.6–5.0 times as long as high. Taiwan................................ S. wushensis Sanborne 38c. Ovipositor slightly upcurving (Fig. 1), with height at mid-length about 0.7–0.8 times width of hind basitarsus. Hind femur 5.1–5.3 times as long as high. Oriental ...........................S. impunctatus sp. n. Sinophorus impunctatus sp. n. (Figs 1–7) Material examined. Holotype: female, China, Jiangxi Province, Ji’an County, Shuangjiang Forest farm, 174 m, 16 April 2009, IT. Paratype. 1 female, China, Jiangxi Province, Quannan County, 1 December 2010, IT. Diagnosis. Face with dense, indistinct punctures, near inner orbit with fine leathery texture. Hind femur 5.1–5.3 times as long as deep. First tergite without lateral longitudinal groove, suture separating petiolar tergite from sternite at midheight of petiole. Tergites impunctate, with fine coriaceous texture. 134 Figure 1. Sinophorus impunctatus sp. n. (female, holotype), habitus, lateral view. Ovipositor 2.0–2.1 times as long as hind femur, height at mid-length about 0.7–0.8 times width of hind basitarsus. Hind femur reddish brown. Median portion of hind tibia yellowish brown, basal and apical portions darkish brown. Comparison. The new species is similar to S. wushensis Sanborne, 1990, but can be distinguished from the latter by the following combination of characters: hind femur 5.1–5.3 times as long as high, first tergite without impressed lateral longitudinal groove. Suture separating petiolar tergite from sternite ap- proximately at midheight of petiole. Ovipositor 2.0–2.1 times as long as hind femur, height at mid-length 0.7–0.8 times width of hind basitarsus. Sinophorus wushensis: hind femur about 4.7 times as long as high; first tergite with moderately impressed lateral, longitudinal groove. Suture separating petiolar tergite from sternite about 0.3 below midheight of petiole. Ovipositor about 2.3 times as long as hind femur and 1.6 times as long as mesosoma, height at mid-length about equal to width of hind basitarsus. Description. F e m a l e . Body length 9.5–10.0 mm. Fore wing length 5.8–6.0 mm. Ovipositor sheath about 3.7 mm. H e a d .

Clypeus weakly and evenly convex, 1.7–1.8 times as wide as high, with fine leathery texture, irregu- larly punctate, with apical margin slightly convex. Mandible wide, rough, with indistinct longitudinal striae. Upper tooth of mandible slightly longer than lower tooth. Malar space roughly sculptered, 0.4–0.5 times as long as basal width of mandible. Gena with fine leathery texture, temples strongly convergent posteriorly. Vertex (Fig. 3) and frons finely sculptured, covered by conspicuous felt-like pubescence.

Ratio of length of flagellomeres first to fifth: 11.0 : 8.0 : 7.0 : 7.0 : 6.9. Occipital carina complete, its lower end reaching base of mandible. M e s o s o m a . Anterior margin of pronotum sharp, as a longitudinal carina, near anterior margin with fine longitu- dinal striations; lateral concavity shiny, with distinct oblique transverse wrinkles; dorsal-porsterior portion with fine leathery texture. Epomia short, distinct. Mesoscutum (Fig. 4) slightly convex, coriaceous with rough punctures; sublateral-median portion with dense, fine, indistinct punctures.
