Diagnosis. Paramere, in lateral view, irregularly lamellar; anterior margin irregularly straight to slightly concave; posterior margin weakly, irregularly wavy; apex irregularly rounded; in dorsal view, bearing blunt anterior and posterior tooth. Aedeagus complex unipartite; in lateral view, dorsal lobe irregularly oval, indented subasally on dorsal outline; ventral process with apical expansion larger than dorsal lobe, irregularly globular.

Description. Adult. Colouration. Head and abdomen lacking distinct striped-pattern, thorax with light yellow striped-pattern. Head and thorax greyish yellow. Occiput dark brown. Genal process light brown. Eye red to almost black; ocelli yellowish. Antenna light brown. Clypeus greyish yellow; rostrum yellow. Thorax greyish yellow, with margins of sclerites brown. Legs greyish yellow. Forewing colourless, dark yellow or ochreous; veins concolorous with membrane or slightly darker. Hindwing almost colourless, transparent. Abdomen dirty whitish. Terminalia yellow to light brown; articulatory sclerites of valvulae conspicuously dark brown. Younger specimens with less expanded dark colour.

Structure. Body length ♁ 2.3–2.8 mm (2.55± 0.21 mm), ♀ $ 2.8–2.9 mm (2.82± 0.05 mm) (4 ♁, 4 ♀). Genal process ( Fig. 162 View FIGURES 148–162 ) subconical with subacute apex, 0.8 times as long as vertex along midline. Antenna 2.6–2.9 times as long as head width; longest terminal seta about as long as segment 10. Apical labium segment 0.1 times longer than head width and 0.5–0.6 times longer than median segment. Forewing ( Fig. 192 View FIGURES 183–192 ) 2.8–3.1 times as long as head width, 2.3 times as long as wide, obovoid, broadly rounded apically; vein M+Cu 1 0.3–0.4 times as long as Cu 1; ratio a/b 1.1–1.9; ratio c/d 0.8–0.9; ratio e/f 0.7–0.8. Surface spinules moderately spaced, forming rhomboids ( Fig. 39 View FIGURES 38–43 ); fully covering all cells except c+sc, areas of surface spinules narrowing near wing margin in cells r 2, m 1, m 2 and cu 1; leaving spinule-free spaces along veins ( Fig. 42 View FIGURES 38–43 ). Metatibia 0.6 times as long as head width.

Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with narrow, almost straight posterior lobe. Paramere, in lateral view ( Figs 280 View FIGURES 274–282 ‾282) 0.9 times as long as proctiger; irregularly lamellar; anterior margin irregularly straight to slightly concave; posterior margin weakly, irregularly wavy; apex irregularly rounded; inner surface ( Fig. 281 View FIGURES 274–282 ) covered with long setae, longer along posterior margin, with row of thick setae along apical anterior margin and several thick setae below sclerotised ridge; in dorsal view ( Fig. 312 View FIGURES 283–312 ), bearing blunt anterior and posterior tooth. Aedeagus ( Fig. 282 View FIGURES 274–282 ) complex unipartite; in lateral view, dorsal lobe irregularly oval, indented subasally on dorsal outline; ventral process relatively straight, with apical expansion larger than dorsal lobe, irregularly globular, bearing long, blunt tubercle.—Female ( Fig. 342 View FIGURES 337–342 ). Proctiger, in lateral view, 1.1 times as long as head width; dorsal outline weakly concave distal to circumanal ring, apical extension almost straight, apex slightly upturned, strongly obliquely truncate; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.6 times as long as proctiger; apex well-developed; ventral outline mostly straight, weakly convex at apex; covered with medium long setae in median third and ventrally throughout, short setae in apical third, long setae at apex, and group of long setae on dorsum subapically, without seta-free patch subapically; in ventral view ( Fig. 372 View FIGURES 363–372 ), lateral margins evenly, weakly narrowing towards narrow, acutely rounded apex.

Measurements (in mm) (1 ♁, 1 ♀). HW ♁ 0.78, ♀ 0.70; AL ♁ 2.04, ♀ 2.00; LAB2 ♁ 0.18, ♀ 0.16; LAB3 ♁ 0.10, ♀ 0.08; FL ♁ 2.40, ♀ 1.98; TL ♁ 0.48, ♀ 0.40; MP 0.28; PL 0.26; DL 0.34; FP 0.82.
