(Figs 132, 162, 192, 280 ‾282, 312, 342, 372, 380)
LSID: urn:lsid:zoobank.org:act: E17103D3-7ED3-4616-9553-E6F5AA86E823
Material examined. Holotype ♁, Brazil: Paraná, Parque Guartelá, -24.5617, -50.2583, 920–950 m, 23–25. vi.2015, Cerrado vegetation (D. Burckhardt & D.L. Queiroz), #171(-) (DZUP, dry).
Paratypes. Paraná: 8 ♁, 13 ♀, same data as holotype (D. Burckhardt & D.L. Queiroz), #171(-) (NHMB, dry, slide mounted, 70% ethanol).
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) 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) 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); 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). 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 ‾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) 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), bearing blunt anterior and posterior tooth. Aedeagus (Fig. 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). 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), 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.
