This new species belongs to the Agriotypus himalensis species group, and it runs to A. lui 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 x its apical width (the latter 2.6 x ); lateromedian longitudinal carinae of propodeum more or less parallel (the latter distinctly convergent apically). It differentiates A. zhejiangensis He & 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 x apical width (the latter 4.6'). It differentiates from other new species proposed in this study by the combination characters: ♀ body reddish brown, mesoscutum without pale spots posteriorly; frons with a longitudinal carina; distance between tentorial pits 3.8 x 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 x its apical width.

Body length 7.3 mm; fore wing length 5.0 mm. Head . Head width 0.9 x its median length. Antennae broken. Temple behind eyes linearly narrowed in dorsal view. Transverse diameter of eye 1.7 x 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 x 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 x length between a tentorial pit and eye. Malar space equal to basal width of mandible. Occipital carina fine, but complete. Figure 7.

A wings B mesosoma, lateral aspect C mesosoma, dorsal aspect D lateral of pronotum E T1, dorsal aspect F head, front aspect G head, dorsal aspect H propodeum, dorsal aspect I metasoma (except T1), dorsal aspect J ovipositor sheath, lateral aspect. Mesosoma . 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 x its basal width, 1.6 x 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. Wings . Fore wing with vein 1cu-a interstitial of M&RS, abscissa of vein M between 2rs-m and 2cu-m 1.25 x 2rs-m; hind wing with vein CU & cu-a intercepted by distal abscissa of CU interrupted at lower 0.2. Metasoma . T1 5.5 x its apical width, 2.0 x 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 x length of hind basitarsus. Colour . 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.
