description: Agriotypus taishunensis sp. nov. Figs 6A, 7 Material examined. <b> <i>Holotype</i>.</b> &amp;female;, China, Zhejiang prov., Taishun, Wuyanling, 34.2°N, 106.8°E, malasy trap, 2005.VIII.1-2, Wang Yiping, No. 200604963 (ZJUH). Diagnosis. This new species belongs to the <i>Agriotypus himalensis</i> species group, and it runs to <i>A. lui</i> Chao in Bennett’s key (2001), but differs in spine of scutellum slender, produced dorsal posteriorly (the latter spine of scutellum thicker, produced posteriorly); T1 5.5 × its apical width (the latter 2.6 ×); lateromedian longitudinal carinae of propodeum more or less parallel (the latter distinctly convergent apically). It differentiates <i>A. zhejiangensis</i> He &amp; Chen from Zhejiang, China in body reddish brown (the latter black); spine of scutellum distinctly upcurved (the latter completely straight); forewing with fuscous longitudinal bands (the latter without); length of T1 5.5 × apical width (the latter 4.6'). It differentiates from other new species proposed in this study by the combination characters: &amp;female; body reddish brown, mesoscutum without pale spots posteriorly; frons with a longitudinal carina; distance between tentorial pits 3.8 × the length between a tentorial pit and eye; scutellum long triangle-shaped; spine of scutellum longer than length of propodeum, produced more or less 30° dorsoposteriorly, apex more or less truncate; T1 5.5 × its apical width. Description. <b>Female.</b> Body length 7.3 mm; fore wing length 5.0 mm. <b> <i>Head</i>.</b> Head width 0.9 × its median length. Antennae broken. Temple behind eyes linearly narrowed in dorsal view. Transverse diameter of eye 1.7 × temple in dorsal view. Frons convex medially, with a longitudinal carina. Antennal scrobe shallow. Ocelli medium-sized, in triangle with base equal to its sides. POL: OD: OOL = 11: 10: 12. Face convex medially with coarse rugosity and dense pubescence. Clypeus nearly pentagonal, 0.9 × its maximum width, roundly convex, thin in apical 0.4, almost truncate on apical margin; summit of covexity of clypeus smoothly rounded in lateral view. Distance between dorsal tentorial pits 3.8 × length between a tentorial pit and eye. Malar space equal to basal width of mandible. Occipital carina fine, but complete. <b> <i>Mesosoma</i>.</b> Pronotum with strong epomia, dorsally curved angulate; lateral of pronotum with more than fine carinae dorso-posteriorly. Mesoscutum finely shiny, with dense punctures; notaulus distinct, meeting in apical 0.2. Scutellum long triangle-shaped, 2.8 × its basal width, 1.6 × length of propodeum; basal half of scutellum with lateral carinae and reticulation-rugosity, convex medially, lateral margin of scutellum paralleled in basal half, tapering towards to apex, spine-like apical half, smooth; in lateral view scutellum roundly curved medially, spine-like in apical half, distinctly up curved, apex tapered, produced 30° dorsoposteriorly; ecepicnemial carina strong, extending to ventral-anterior of mesopleuron; mesopleural sulcus complete; sternaulus strong. Propodeum finely coriaceous-punctate, lateromedian longitudinal carinae more or less parallel; lateral longitudinal carinae straight, complete and paralleled with lateromedian longitudinal carinae. <b> <i>Wings</i>.</b> Fore wing with vein 1cu-a interstitial of M&amp;RS, abscissa of vein M between 2rs-m and 2cu-m 1.25 × 2rs-m; hind wing with vein CU &amp; cu-a intercepted by distal abscissa of CU interrupted at lower 0.2. <b> <i>Metasoma</i>.</b> T1 5.5 × its apical width, 2.0 × length of propodeum; T1 corasely punctate, spiracles situated in basal 0.3, lateral margin of petiole behind spiracles parallel; lateromedian carinae and dorsolateral carinae complete and strong, reaching to apex. T2 convex on basomedian area, with a pair of short carinae medially and a lateral carina before spiracle. Ovipositor sheath 0.9 × length of hind basitarsus. <b> <i>Colour</i>.</b> Reddish brown; metasoma apically and legs dark brown. Fore wing with three fuscous longitudinal bands: basal band on basal 0.1-0.5 of forewing, but with a wide hyaline fascia occupying middle of cell R; substigmal band below stigma and distal band in distal of forewing; hind wing nearly hyaline. Host. Unknown. Distribution. China (Zhejiang). Etymology. Name derived from the name of location where the holotype was collected.
