description: Agriotypus maae sp. nov. Figs 3A, 4 Material examined. <b> <i>Holotype</i>.</b> &amp;female;, China, Shaanxi prov., Qinling, Tiantaishan, 34.2°N, 106.8°E, 2000 m, 1998.VI.8, Du Yuzhou, No. 983376 (ZJUH). <i>Paratypes</i>: 1&amp;female;, China, Shaanxi prov., Zhouzhi Houzhenzi, 1990.V.24, Du Yuzhou, No. 984474 (TARI); 1&amp;female;, China, Shaanxi prov., Zhouzhi Houzhenzi, 1990.V.24, Du Yuzhou, No. 984475 (ZJUH); 1&amp;female;, China, Shaanxi prov., Foping Longcaoping, 33.5°N, 107.9°E, 1998.VI.4, Ma Yun, No. 981986 (ZJUH). Diagnosis. This new species belongs to the <i>Agriotypus himalensis</i> species group, and it runs to <i>A. maculiceps</i> Chao in Bennett’s key (2001), but differs in frons with longitudinal carina (the latter without); pronotum finely punctate-rugose (the latter reticulate-rugose); scutellum entirely black (the latter pale in apical half), spine of scutellum produced more or less 85° dorsoposteriorly (the latter 35-45°). It differentiated from other new species proposed in this study by the combination characters: &amp;female; vertex near eyes and mesoscutum medio-posteriorly with large reddish brown patch; frons with a longitudinal carina; mesoscutum mostly glabrous; spine of scutellum produced 85° dorsoposteriorly. Description. <b>Female.</b> Body length 7.4 mm; fore wing length 5.8 mm. <b> <i>Head</i>.</b> Head width 0.8 × its median length. Antennae 23-segmented, 0.5 × length of forewing. Temple behind eyes distinct narrowed in dorsal view. Transverse diameter of eye 1.0 × temple in dorsal view. Frons convex medially, with longitudinal carina. Antennal scrobe more or less shallow. Ocelli in triangle with base equal to its sides. POL: OD: OOL = 12: 11: 24. Face convex medially with coarse rugosity and dense pubescence. The area between antennal socket with a glabrous circular tubercle. Clypeus nearly pentagonal, almost equal to its maximum width, roundly convex, flat and rugose with punctuation in basal 0.6; thin in apical 0.4, without distinct rugosity, bluntly rounded on apical margin; summit of covexity of clypeus smoothly rounded in lateral view. Distance between tentorial pits 1.3 × length between a dorsal tentorial pit and eye. Malar space 1.15 × basal width of mandible. Occipital carina fine, but complete. <b> <i>Mesosoma</i>.</b> Pronotum with fine epomia, dorsally curved angulate posteriorly; lateral of pronotum glabrous, reticulate in dorsal half, dense pubescent in ventral half. Mesoscutum mostly glabrous, shiny, with fine punctulation and rugosity partly; median lobe medially and lateral lobe mostly smooth; notaulus narrow, more or less crenulated, meeting in apical 0.3. Scutellum long triangle-shaped, 2.5 × its basal width, 1.2 × length of propodeum; basal half of scutellum with lateral carinae and reticulation-rugosity, convex medially, lateral margin of scutellum paralleled in basal 2/3, tapering towards to apex, spine-like apical half, smooth; in lateral view scutellum roundly curved medially, spine-like in apical 0.4, distinctly up curved, apex tapered, produced 85° dorsoposteriorly; ecepicnemial carina strong, extending to ventral-anterior of mesopleuron; mesopleural sulcus complete; sternaulus strong. Propodeum punctate-reticulate; lateral longitudinal carinae straight and strong and paralleled with lateromedian longitudinal carinae. <b> <i>Wings</i>.</b> Fore wing with vein 1cu-a distad of M&amp;RS, abscissa of vein M between 2rs-m and 2m-cu 0.8 × 2rs-m; hind wing with vein CU &amp; cu-a interrupted by distal abscissa of CU at lower 0.15. <b> <i>Metasoma</i>.</b> T1 3.5 × its apical width, 1.5 × length of propodeum; T1 finely reticulate-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. T2 and following tergite densely punctulate. Ovipositor sheath 2.2 × length of hind basitarsus. <b> <i>Colour</i>.</b> Black, vertex near eyes and mesoscutum medio-posteriorly with large reddish brown patch. Hypopygium yellowish brown apically. Leg black. Fore wing with three dark brown 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. <b> <i>Variation</i>.</b> Body length 7.0-7.4 mm; fore wing length 5.6-5.8 mm. Antennae 25-segmented. Transverse diameter of eye 0.9 × temple in dorsal view. Scutellum 2.0 × its basal width, 1.4 × length of propodeum. T1 4.1 × its apical width, 2.2 × length of propodeum. <b>Male.</b> Unknown. Host. Unknown. Distribution. China (Shaanxi). Etymology. This species is named in honour of Mrs Ma Yun, who collected many materials of <i>Agriotypus</i> and provided a lot of help in our research work.
