description: Agriotypus yangae sp. nov. Figs 6B, 8 Material examined. <b> <i>Holotype</i>.</b> &amp;female;, China, Shaanxi prov., Qinling, Tiantaishan, 34.2°N, 106.8°E, 1998.VI.9, Sun Changhai, No. 985922 (ZJUH). Diagnosis. This new species belongs to the <i>Agriotypus himalensis</i> species group, and it runs to <i>A. chaoi</i> Bennett in Bennett’s key (2001), but differs in &amp;female; scutellum funnel-shaped (the latter triangle-shaped); spine of scutellum black (the latter light brown apical half); mesoscutum punctate and pubescent (the latter sparsely pubescent and impunctate postero-medially). It differentiates from other new species proposed in this study by the combination characters: &amp;female; frons without a longitudinal carina; mesoscutum and scutellum completely black, without pale spots; mesoscutum pubescent; scutellum funnel-shaped; length of scutellum 1.8 × its basal width; spine of scutellum short, distinctly obliquely upward, rounded apically; T1 3.4 × its apical width. Description. <b>Female.</b> Body length 7.2 mm; fore wing length 6.0 mm. <b> <i>Head</i>.</b> Head width equal to its median length. Antennae 26-segmented, 0.7 × length of forewing. Temple behind eyes roundly narrowed in dorsal view. Transverse diameter of eye 1.2 × temple in dorsal view. Frons convex medially, with shallow depression near middle ocelli, without longitudinal carina. Antennal scrobe deep, with a weak carina on its lateral margin parallel to inner orbit of eye. Ocelli medium-sized, in triangle with base equal to its sides. POL: OD: OOL = 15: 13: 22. Face distinctly convex medially with coarse rugosity and dense pubescence. Area between antennal socket with a glabrous tubercle. Clypeus nearly pentagonal, equal to its maximum width, roundly convex, more or less flat medially and rugose with punctuation in basal half; thin apically, finely strigate, slightly rounded on apical margin; summit of covexity of clypeus smoothly rounded in lateral view. Distance between dorsal tentorial pits 1.7 × length between a tentorial pit and eye. Malar space 1.6 × basal width of mandible. Occipital carina complete. <b> <i>Mesosoma</i>.</b> Pronotum with long and strong epomia, portion dorsal to pronotal furrow curved sigmoidally; lateral of pronotum with more than seven fine carinae dorso-posteriorly. Mesoscutum punctate-rugose; notaulus deep, meeting in apical 0.2. Scutellum funnel-shaped, 1.8 × its basal width, 1.1 × length of propodeum; basal half of scutellum with lateral carinae and punctuation-rugosity, convex medially, lateral margin of scutellum paralleled in basal 2/3, tapering towards to apex in apical 1/3; in lateral view scutellum less roundly curved medially, distinctly obliquely upward, apex more or less rounded, produced 10° dorsoposteriorly. Mesopleuron and metapleuron finely punctuate and pubescent; ecepicnemial carina strong, only extending to ventral-anterior of mesopleuron; mesopleural sulcus complete; sternaulus strong. Propodeum punctate-rugose; lateromedian longitudinal carinae weakly convergent posteriorly; lateral longitudinal carinae straight, complete 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 2cu-m 1.25 × 2rs-m; hind wing with vein CU &amp; cu-a intercepted by distal abscissa of CU interrupted at lower 0.15. <b> <i>Metasoma</i>.</b> T1 3.4 × its apical width, 1.65 × length of propodeum; T1 finely irregularly rugose-striate, transverse rugose before spiracles, spiracles situated in basal 0.3, widest at level of spiracles; lateromedian carinae and dorsolateral carinae complete and strong, reaching to apex. T2 with a pair of short carinae medially and a lateral carina before spiracle; T2 densely finely strigose. T3 and following tergite densely punctulate. Ovipositor sheath 0.8 × length of hind basitarsus. <b> <i>Colour</i>.</b> Black. Apical of four tergites, sternites and ovipositor reddish brown. Leg black. Fore wing faintly infuscate, with three slightly fuscous longitudinal bands: basal band near cu-a; substigmal band below stigma and distal band in distal 0.25 of forewing; hind wing more or less hyaline. <b>Male.</b> Unknown. Host. Unknown. Distribution. China (Shaanxi). Etymology. This species is named in honour of Dr Yang Lianfang, the famous entomologist who studied the taxonomy of Trichoptera in China.
