Diagnosis. Body light straw-coloured; head and abdomen lacking distinct striped-pattern. Surface spinules fully covering all cells; covering cells up to veins apically. Paramere, in lateral view, irregularly lamellar, strongly sinuous; posterior margin strongly expanded and convex in basal two thirds; apex irregularly rounded, slightly notched anteriorly, directed posteriorly; in dorsal view, sclerotised ridge bearing small anterior and larger posterior tooth. Aedeagus complex unipartite; in lateral view, dorsal lobe subtriangular, indented submedially on dorsal outline; ventral process with apical expansion subequal in size with dorsal lobe, globular, bearing long, blunt tubercle.

Description. Colouration. Head and abdomen lacking distinct striped-pattern, thorax dorsum sometimes with faint striped-pattern. Head and thorax light straw-coloured. Vertex whitish; genal process usually slightly darker than head. Eye grey to dark red; ocelli colourless. Antenna yellow. Clypeus concolorous with body, slightly lighter medially and slightly darker along edges; rostrum light yellow. Thorax with margins of sclerites slightly darker. Metascutellum almost entirely white. Forewing yellowish, sometimes darker apically, yellow around Cu 1b and sometimes slightly around M 3+4 and Cu 1a; sometimes with yellow median spot in cells m 1, m 2, cu 1 apically; veins light yellow; pterostigma concolorous or slightly lighter than veins; sometimes with yellow spots around radular areas. Hindwing colourless. Fore- and midleg pale yellow, usually with tarsi darker, hindleg light yellow. Abdomen light straw-coloured to whitish; intersegmental membranes concolorous with rest of abdomen; spiracular sclerites concolorous with abdomen. Male terminalia light yellow. Female terminalia light yellow, proctiger dark yellow apically.

Structure. Body length ♁ 2.0– 2.2 mm (2.18± 0.12 mm), ♀ 2.3–2.5 mm (2.42± 0.08 mm) (4 ♁, 5 ♀). Genal pro-cess ( Fig. 154 View FIGURES 148–162 ) expanded, irregularly narrowing towards broadly or narrowly rounded apex, 0.4–0.6 times as long as vertex along midline. Antenna 2.4–2.5 times as long as head width; longest terminal seta about as long as segment 10. Apical labium segment 0.1–0.2 times longer than head width and 0.7 times longer than median segment. Forewing ( Fig. 184 View FIGURES 183–192 ) 2.6–2.8 times as long as head width, 2.3–2.5 times as long as wide, obovoid, narrowly or broadly rounded apically; veins bearing long, dense microscopic setae; vein M+Cu 1 0.3–0.4 times as long as Cu 1; ratio a/b 1.7–2.2; ratio c/d 0.7–0.8; ratio e/f 1.1–1.7. Surface spinules moderately spaced, forming rhomboids ( Fig. 39 View FIGURES 38–43 ), rarely densely spaced in cell r 1, forming irregular groups somewhat separated from each other ( Fig. 41 View FIGURES 38–43 ); fully covering all cells; leaving spinule-free spaces along veins ( Fig. 42 View FIGURES 38–43 ), covering cells up to veins apically ( Fig. 43 View FIGURES 38–43 ). Radular spinules sometimes present in r 2 but 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 256 View FIGURES 256–264 ‾258) 0.9 times as long as proctiger; irregularly lamellar, strongly sinuous; anterior margin strongly rounded apically, almost straight before apex; posterior margin angulate or slightly rounded and expanded in apical third, strongly expanded and convex in basal two thirds; apex irregularly rounded, slightly notched anteriorly, directed posteriorly; inner surface ( Fig. 257 View FIGURES 256–264 ) covered with short setae, slightly longer basally and long posterior margin, with row of thick setae along apical anterior margin, group of thick setae below sclerotised ridge and on apical posterior margin, along with several stout setae; in dorsal view ( Fig. 304 View FIGURES 283–312 ), sclerotised ridge bearing small anterior and larger posterior tooth. Aedeagus ( Fig. 258 View FIGURES 256–264 ) complex unipartite; in lateral view, dorsal lobe subtriangular, indented submedially on dorsal outline; ventral process weakly to strongly upturned, with apical expansion subequal in size with dorsal lobe, globular, bearing long, blunt tubercle.—Female (Fig. 334). Proctiger, in lateral view, 0.8–0.9 times as long as head width; dorsal outline weakly concave distal to circumanal ring, apical extension sinuous, apex slightly upturned, obliquely rounded to smoothly obliquely truncate; circumanal ring 0.3–0.4 times as long as proctiger. Subgenital plate, in lateral view, 0.5–0.6 times as long as proctiger; apex well-developed; ventral outline almost straight to slightly sinuous, sometimes slightly notched submedially or subapically; covered with long setae in subasal quarter and ventrally throughout, short setae in apical half, longer setae at apex, and long setae on dorsum subapically, with seta-free patch subapically; in ventral view ( Fig. 364 View FIGURES 363–372 ), lateral margins evenly, strongly narrowing at about half towards slightly broad, subtruncate apex.
