Material examined. Holotype ♁, Brazil: Mato Grosso, Sinop , -11.8645, -55.6068, 360 m, 25.viii.2012 (D.L. Quei-roz), #336 ( DZUP 215411View Materials, dry).GoogleMaps 

Paratypes. Mato Grosso: 3 ♁, 5 ♀, 1 immatures, same data as holotype (D.L. Queiroz), #336 ( DZUP, NHMB, dry, slide mounted, 70% ethanol)GoogleMaps  .— São Paulo: 1 ♁, 1 ♀, Araraquara, Fazenda Cambuhy, 19.x.2005, citrus grove, suction trap (P. Yamamoto) ( FSCA, 70% ethanol);  1 ♁, Matão, Fazenda Marchesan, 20.ix.2007, citrus grove, suc-tion trap (P. Yamamoto) ( FSCA, 70% ethanol); 1 ♁, same but 1.x.2007 (P. Yamamoto) ( FSCA, 70% ethanol)  .

Diagnosis. Paramere, in lateral view, clavate, weakly expanded apically; posterior margin irregularly sinuous, forming small lobe in apical third; inner surface bearing group of stout setae on apical posterior margin. Aedeagus complex tripartite; in lateral view, lateral lobule subequal in size with median lobule, broadly rounded apically; membranous pouch elongate; ventral process with apical expansion subequal in size with dorsal lobe, oval.

Description. Colouration. Body with white striped-pattern; variation: vertex with stripe along posterior margin absent; mesoscutellum with a stripe along anterior margin or with an anterolateral marking; older specimens with markings with dark outline. Head and thorax dark yellow. Gena sometimes slightly darker anteriorly and ventrally; genal process concolorous with vertex. Eye grey to dark red; ocelli colourless to orange. Antenna light yellow, segments 1–2 concolorous with head. Clypeus concolorous with body, darker along edges; rostrum light yellow to dark yellow. Thorax with margins of sclerites darker. Forewing colourless to slightly yellowish, sometimes slightly darker around Cu 1b; veins light yellow to light yellowish-brown; pterostigma concolorous or slightly darker than veins. Hindwing colourless. Legs concolorous with body, femora usually slightly darker, metatibia lighter. Abdomen dark yellow to yellowish-brown, yellowish-brown to brown ventrally; intersegmental membranes light strawcoloured; spiracular sclerites concolorous with sternites. Male terminalia dark yellow. Female terminalia irregularly dark yellow and yellowish-brown, proctiger usually darker apically.

Structure. Body length ♁ 2.1 mm, ♀ 2.2–2.5 mm (2.35± 0.16 mm) (1 ♁, 2 ♀). Genal process ( Fig. 145View FIGURES 133–147) sub-conical, irregularly narrowing towards acute apex, 0.5–0.6 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 0.5–0.7 times longer than median segment. Forewing ( Fig. 175View FIGURES 173–182) 2.8 times as long as head width, 2.2 times as long as wide, obovoid, broadly rounded apically; vein M+Cu 1 0.4–0.5 times as long as Cu 1; ratio a/b 1.8; ratio c/d 0.7–0.8; ratio e/f 0.6–1.0. Surface spinules moderately spaced, forming rhomboids ( Fig. 39View FIGURES 38–43); covering apical half or apex of cells r 1 and r 2, around radular areas of cells m 1, m 2 and cu 1 (sometimes much reduced), m 2 basally, and most of cell cu 2; leaving spinule-free spaces along veins ( Fig. 42View FIGURES 38–43). Metatibia 0.7 times as long as head width.

Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, strongly tapered, weakly down-curved posterior lobe. Paramere, in lateral view ( Figs 229View FIGURES 229–237 ‾231) 0.9 times as long as proctiger; clavate, weak-ly expanded apically; anterior margin sinuous; posterior margin irregularly sinuous, forming small lobe in apical third; inner surface ( Fig. 230View FIGURES 229–237) covered with long setae, 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. 295View FIGURES 283–312), sclerotised ridge bearing sclerotised posterior tooth. Aedeagus ( Fig. 231View FIGURES 229–237) complex tripartite; in lateral view, dorsal lobe with flattened, elongate median lobule; lateral lobule subequal in size with median lobule, broadly rounded apically; membranous pouch elongate; ventral process weakly upturned, with apical expansion subequal in size with dorsal lobe, oval, bearing long, blunt tubercle.—Female ( Fig. 325View FIGURES 325–330). Proctiger, in lateral view, 1.1 times as long as head width; dorsal outline weakly to moderately concave distal to circumanal ring, apical extension sinuous, apex strongly upturned, 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 almost straight to slightly sinuous; covered with medium long setae in subasal quarter and ventrally throughout, short setae in apical half, long setae at apex, and group of long setae on dorsum subapically and submedially with seta-free patch subapically; in ventral view ( Fig. 355View FIGURES 343–362), lateral margins unevenly, weakly narrowing at half towards broad, subtruncate apex.

Measurements (in mm) (1 ♁, 1 ♀). HW ♁ 0.58, ♀ 0.63; AL ♁ 1.44, ♀ 1.49; LAB2 ♁ 0.14, ♀ 0.15; LAB3 ♁ 0.10, ♀ 0.08; FL ♁ 1.60, ♀ 1.78; TL ♁ 0.42, ♀ 0.45; MP 0.24; PL 0.22; DL 0.28; FP 0.68.
