LSID: urn:lsid:zoobank.org:act: 1179A4F3-45B1-4DCC-ACC1-A00C75736A09
Material examined. Holotype ♁, Brazil: Mato Grosso, Sinop, -11.8645, -55.6068, 360 m, 25.viii.2012 (D.L. Quei-roz), #336 (DZUP 215411, dry).
Paratypes. Mato Grosso: 3 ♁, 5 ♀, 1 immatures, same data as holotype (D.L. Queiroz), #336 (DZUP, NHMB, dry, slide mounted, 70% ethanol).— 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. 145) 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. 175) 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. 39); 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. 42). 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 229 ‾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. 230) 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. 295), sclerotised ridge bearing sclerotised posterior tooth. Aedeagus (Fig. 231) 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. 325). 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. 355), 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.
