Surface spinules around radular areas of cells m 1, m 2and cu 1, sometimes much reduced. Paramere, in lateral view, clavate, weakly expanded apically; anterior margin weakly and irregularly sinuous; posterior margin angulate and expanded in apical third, weakly convex in basal two thirds; apex subtruncate, slightly directed posteriorly; sclerotised ridge medially. Aedeagus complex unipartite; in lateral view, ventral process with apical expansion larger than dorsal lobe.   Description.Colouration. Body with whitish striped-pattern; variation: vertex with stripe along lateral margins weak and along posterior margin absent; mesopraescutum with lateral stripes fused to lateral spots on posterior margin; older specimens with markings with dark outline. Head and thorax dark yellow, yellowish-brown to reddish. Gena sometimes slightly darker to brownish ventrally; genal process yellowish to light brown. Eye grey to red; ocelli orange. Antenna light yellow, segments 1–2 slightly darker. Clypeus dark yellow to yellowish-brown, lighter medially and darker along edges; rostrum light yellow to yellow. Thorax sometimes darker than head, usually with margins of sclerites darker. Pronotum sometimes lighter anteriorly. Mesopraescutum sometimes with posterior half irregularly coloured. Forewing slightly yellowish, sometimes slightly darker around Cu 1b; veins yellow or light brown; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Legs light yellow with pro- and meso- femora dark yellow, protarsus usually darker. Abdomen dark yellow, yellowish-brown to light brown; intersegmental membranes light straw-coloured to reddish; spiracular sclerites concolorous or slightly darker than tergites. Male terminalia light to dark yellow. Female terminalia dark yellow, usually darker apically and around anus. Structure. Body length ♁ 2.0– 2.2 mm(2.12± 0.06 mm), ♀ 2.3–2.4 mm(2.36± 0.05 mm) (5 ♁, 5 ♀). Genal process ( Fig. 141) subconical, evenly or irregularly narrowing towards acute or subacute apex, 0.5–0.6 times as long as vertex along midline. Antenna 2.1–2.3 times as long as head width; longest terminal seta slightly shorter than segment 10. Apical labium segment 0.2 times longer than head width and 0.7–0.8 times longer than median segment. Forewing ( Fig. 171) 2.7–3.0 times as long as head width, 2.1–2.3 times as long as wide, suboval, oval or subrhomboidal narrowly or slightly broadly rounded apically; vein M+Cu 10.3–0.4 times as long as Cu 1; ratio a/b 1.4–1.7; ratio c/d 0.7–0.8; ratio e/f 0.5–0.8. Surface spinules moderately spaced, forming rhomboids ( Fig. 39); covering apical half of cells r 1and r 2, around radular areas of cells m 1, m 2and cu 1(sometimes much reduced), m 2basally, and most of cell cu 2; leaving spinule-free spaces along veins ( Fig. 42). Radular spinules sometimes present in r 2but inconspicuous. Metatibia 0.8 times as long as head width. Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, blunt, weakly to strongly down-curved posterior lobe. Paramere, in lateral view ( Figs 217‾219) 0.8 times as long as proctiger; clavate, weakly expanded apically; anterior margin weakly and irregularly sinuous; posterior margin angulate and expanded in apical third, weakly convex in basal two thirds; apex subtruncate, slightly directed posteriorly, with sclerotised ridge medially ( Fig. 218); inner surface ( Fig. 218) covered with short setae, longer basally and along posterior margin, with row of thick setae along apical anterior margin, several thick setae below sclerotised ridge, and group of stout setae on apical posterior margin; in dorsal view ( Fig. 291), sclerotised ridge subrectangular, slightly larger anteriorly, bearing posterior tooth. Aedeagus ( Fig. 219) complex unipartite; in lateral view, dorsal lobe obovoid; ventral process weakly upturned, with apical expansion larger than dorsal lobe, irregularly globular, bearing long, conical tubercle.—Female ( Fig. 321). Proctiger, in lateral view, 1.0–1.1 times as long as head width; dorsal outline weakly to strongly concave distal to circumanal ring, apical extension almost straight to sinuous, apex moderately to strongly upturned, smoothly to strongly obliquely truncate; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.5 times as long as proctiger; apex well-developed; ventral outline slightly sinuous to slightly convex, sometimes slightly notched submedially; covered with medium long setae in median third and ventrally throughout, shorter setae in apical third, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view ( Fig. 351), lateral margins abruptly narrowing at half, with apical half strongly narrowing towards broad, subtruncate apex. Measurements (in mm) (3 ♁, 3 ♀).
