Diagnosis.Body pale yellow, contrasting from conspicuously dark veins; surface spinules fully covering cells m 1, m 2, cu 1and cu 2. Paramere, in lateral view, lamellar; anterior margin almost straight before apex; posterior margin almost straight in apical two thirds; apex with prominent median projection, indented posteriorly. Aedeagus complex unipartite; in lateral view, dorsal lobe much expanded and almost as long as ventral process; ventral process with apical expansion weak, considerably smaller than dorsal lobe. Female proctiger, in lateral view, with apex straight to slightly upturned, smoothly transversally truncate to irregularly rounded. Female subgenital plate, in lateral view, with ventral outline sinuous to convex along basal half, slightly notched submedially or subapically, and convex apically; lacking seta-free patch subapically.
Description.Colouration. Head, pronotum and abdomen lacking distinct striped-pattern, rest of thorax with faint light straw-coloured striped-pattern. Head light straw-coloured to pale yellow; genal process sometimes slightly darker than head apically. Eye dark red; ocelli colourless to orange.Antenna yellowish-brown, segments 1–2 concolorous with head. Clypeus pale yellow, slightly lighter medially; rostrum light yellow. Thorax pale yellow, with margins of sclerites slightly darker. Mesopraescutum sometimes with anterior half yellow. Metascutellum almost entirely light straw-coloured. Forewing colourless; veins conspicuously dark, sometimes light yellow in basal half of forewing and brownish in apical half; pterostigma concolorous with veins. Hindwing colourless. Fore- and midleg pale yellow with tarsi darker, hindleg light yellow. Abdomen light straw-coloured to pale yellow; intersegmental membranes light straw-coloured; spiracular sclerites concolorous with abdomen. Male terminalia irregularly pale yellow. Female terminalia pale yellow, proctiger with apical half brown, subgenital plate brown apically. Structure. Body length ♁ 2.3–2.6 mm(2.45± 0.15 mm), ♀ 2.6–2.8 mm(2.66± 0.12 mm) (5 ♁, 5 ♀). Genal pro-cess ( Fig. 148) expanded, irregularly narrowing towards broadly or narrowly rounded apex, 0.4–0.6 times as long as vertex along midline. Antenna 2.4–2.7 times as long as head width; longest terminal seta slightly shorter than segment 10. Apical labium segment 0.1–0.2 times longer than head width and 0.6–0.7 times longer than median segment. Forewing ( Fig. 178) 2.7–2.9 times as long as head width, 2.3–2.5 times as long as wide, obovoid, narrowly or broadly rounded apically; vein M+Cu 10.3–0.4 times as long as Cu 1; ratio a/b 1.7–1.9; ratio c/d 0.7–0.9; ratio e/f 0.7–1.0. Surface spinules distinctly ( Fig. 38) to moderately ( Fig. 39) spaced, forming rhomboids; covering apical half or third of cells r 1and r 2, fully covering cells m 1, m 2, cu 1and cu 2; leaving spinule-free spaces along veins ( Fig. 42). Radular spinules sometimes present in r 2but inconspicuous. Metatibia 0.6–0.7 times as long as head width. Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, blunt, strongly downcurved posterior lobe. Paramere, in lateral view ( Figs 238‾240) 1.0–1.1 times as long as proctiger; lamellar; anterior margin rounded apically, almost straight before apex; posterior margin almost straight in apical two thirds, expanded posteriorly in basal third; apex with prominent median projection, indented posteriorly; inner surface ( Fig. 239) covered with short setae, longer on basal posterior projection an along posterior margin, with row of thick setae along apical anterior margin, group of thick setae below sclerotised ridge and on apical posterior margin; in dorsal view ( Fig. 298), apex sclerotised forming squarish, inward and posteriorly directed process.Aedeagus ( Fig. 240) complex unipartite; in lateral view, dorsal lobe much expanded and almost as long as ventral process; ventral process strongly upturned, with apical expansion weak, considerably smaller than dorsal lobe, bearing long, conical tubercle.—Female ( Fig. 328). Proctiger, in lateral view, 0.9 times as long as head width; dorsal outline weakly to moderately concave distal to circumanal ring, apical extension almost straight, apex straight to slightly upturned, smoothly transversally truncate to irregularly rounded; circumanal ring 0.3–0.4 times as long as proctiger. Subgenital plate, in lateral view, 0.6 times as long as proctiger; apex well-developed; ventral outline sinuous to convex along basal half, slightly notched submedially or subapically, and convex apically; covered with medium long setae in subasal quarter, short setae in apical half, long setae at apex, without seta-free patch subapically; in ventral view ( Fig. 358), lateral margins evenly, weakly narrowing towards broad, rounded apex. Measurements (in mm) (5 ♁, 3 ♀). HW ♁ 0.63–0.67 (0.65±0.02), ♀0.71–0.73 (0.72±0.01); AL ♁ 1.58–1.70 (1.64±0.05), ♀1.73–1.79 (1.75±0.03); LAB2 ♁ 0.15, ♀0.16–0.17 (0.16±0.01); LAB3 ♁ 0.09–0.11 (0.10±0.01), ♀0.10; FL ♁ 1.75–1.90 (1.83±0.06), ♀1.98–2.07 (2.02±0.05); TL ♁ 0.41–0.44 (0.43±0.01), ♀0.46–0.48 (0.47±0.01); MP 0.27–0.29 (0.28±0.01); PL 0.28–0.29 (0.29±0.01); DL 0.33–0.37 (0.36±0.02); FP 0.64–0.67 (0.66±0.02).
