Zheng sp. nov. ( Figures 1 , 2 ) Male Body small. Head large, shorter than pronotum. Fastigium vertices narrow, acutangular, lateral ridges distinct. Vertex with obviously median carina. Fastigial foveola quadrilateral, twice as long as wide. Frons oblique in lateral view, frontal costa broad, with shallow longitudinal sulcus, lateral margins paralleled, below median ocelli lightly contracted. Antenna filiform, reaching basal area of hind femora. Eyes oval, longitudinal diameter 1.3 times transverse diameter, 2.5 times as wide as subocular furrows. Anterior margin of pronotum straight, posterior margin obtuse angle protruding; median and lateral carinae distinct, lateral carina slightly curved in prozona; hind transverse sulcus situated near posterior margin; prozona slightly longer metazona (as 1.14 times); lateral lobes higher than long, anterior angle obtuse, posterior angle right-angled. Mesosternum lobes broader than long, mesosternal interspace tetragonal, posterior margin of metasternal lobes contiguous. Tegmina and hind wings developed, reaching to knee lobe apex of hind femora; cubital area of tegmina much broader, two to three times as wide as medial area, costal area equal to cubital area, precostal area with intercalary vein. Hind femora up to five times as broad, upper median carina smooth, apex of lower lateral genicular lobe rounded; hind tibiae with 10 external and 12 internal ventral spines, outer apical spine absent, inner and outer apical spurs almost equal; arolium long, surpassing half claws. Tympanum developed, nearly rounded. Supra-anal plate shield-like, medial margin protruding in middle, with median longitudinal furrow on basal half. Cercus long conical, apex acute, beyond apex of supra-anal plate. Subgenital plate short conical, terminalia obtuse. Epiphallus bridge narrow, with two pairs of blunt rounded lophi, the inner pair located in inner side of lateral plate; ancorae distinct, slightly curved; anterior projections blunt, posterior projections protruding and acutangular (see Figure 2A ). Phallic complex with long, obtuse apical valves of penis and comparatively broad basal valves of penis; posterior process of cingulum, from above, almost rounded trapezoid; zygoma narrow (see Figure 2B,C ).

Amplicubitoacris flavistriolata Zheng sp. nov. (A) Epiphallus, dorsal view; (B) phallic complex, lateral view; (C) phallic complex, dorsal view. Scale bars 1 mm. Colouration Body yellowish brown. Vertex with a yellow longitudinal stripe, lateral margins with broad black stripes, stripes protruding pronotum. Antenna black. Tegmina light brown, with blackish brown vein stripes, apical area of hind wings light brown, apex with blackish spots. Hind femora yellowish brown, genicular area of hind femora black, hind tibiae yellowish brown, basal area black. Female Body medium to small ( Figure 1C ). Lateral carinea of frontal costa hardly paralleled, with shallow longitudinal furrow, longitudinal diameter of eyes 1.5 times transverse diameter and 1.8 times subocular furrows. Antennae short, reaching posterior margin of pronotum, prozona longer than metazona (1.1 times), mesosternal interspace broader than long, metasternal lobes divided. Cubital area of tegmen much broad, as 1.8 times as medial area, precostal area, medial area and cubital area with intercalary veins. Length of hind femora 5.5 times width; hind tibiae with 12 external and 11 internal spines on dorsal margin, outer apical spine absent. Supra-anal plate triangular, circus short conical, ovipositor short, apex hook-shaped, subgenital plate longer than broad, triangular protruding behind in middle. Colouration Colouration as for male. Type material Holotype male, China : Chayu (Xiachayu), Xizang , 13 October 2007 , coll. Shi Fu- Ming . Paratypes : two males , one female , other data as holotype ; one female , 2 October 2007 ; one male , 3 October 2007 ; one female , 8 October 2007 ; two males , two females , 10 October 2007 , other data same as holotype . Measurements (in mm) Body length: male 13.0–15.5, female 19.5–20.0; pronotum length: male 2.8–3.0, female 4.0–4.5; tegmen length: male 10.0–11.0, female 13.0–14.0; hind femur length: male 8.5–9.0, female 11.5–12.0. Etymology The name originated from the Latin adjectives flavus , meaning golden, and striatus , meaning plicate.
