Diagnosis. Surface spinules fully covering cells m 1, m 2, and cu 1, sometimes restricted to radular areas. Paramere, in lateral view, clavate, strongly expanded apically; anterior margin expanding dorsally and anteriorly in apical third; apex strongly indented in anterior third; sclerotised ridge in posterior half; in dorsal view, sclerotised ridge smoothly inward directed, bearing posterior tooth after deep indention. Aedeagus complex unipartite; in lateral view, ventral process with apical expansion larger than dorsal lobe.
Description. Colouration. Body with white striped-pattern; variation: older specimens with markings with dark outline. Head and thorax light yellowish-brown, yellow, orange to brownish-orange. Gena sometimes slightly darker to brown anteriorly and ventrally; genal process concolorous with head, greyish yellow to yellowish-brown. Eye grey to dark red; ocelli colourless to orange. Antenna yellow, segments 1–2 slightly darker or concolorous with head. Clypeus yellowish to orange, slightly lighter medially; rostrum light yellow, dark yellow to orange. Thorax sometimes slightly darker than head to brown ventrally, sometimes with margins of sclerites darker. Mesopraescutum sometimes with posterior half irregularly coloured. Forewing colourless to yellowish, sometimes yellow around Cu 1b and seldom around M 3+4 and Cu 1a; veins light yellow to yellowish-brown; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Fore- and midleg dark yellow with femora yellowish-brown, hindleg light yellow with femur yellowish-brown.Abdomen light yellowish-brown, yellow, orange to medium brown, sometimes darker ventrally; intersegmental membranes light straw-coloured to orange; spiracular sclerites concolorous with tergites. Male terminalia light yellow to yellowish-brown. Female terminalia light yellow, orange to yellowishbrown, proctiger brown apically and sometimes dorsally.
Structure. Body length ♁ 2.3–2.6 mm (2.44± 0.13 mm), ♀ 2.5–2.7 mm (2.59± 0.10 mm) (4 ♁, 5 ♀). Genal pro-cess (Fig. 142) expanded, irregularly narrowing towards broadly or narrowly rounded apex, 0.5–0.7 times as long as vertex along midline. Antenna 2.1–2.5 times as long as head width; longest terminal seta about as long as segment 10. Apical labium segment 0.2 times longer than head width and 0.6–0.7 times longer than median segment. Forewing (Fig. 172) 2.9–3.0 times as long as head width, 2.2–2.3 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 1.6–1.9; ratio c/d 0.8–0.9; ratio e/f 0.6–0.9. Surface spinules distinctly (Fig. 38) to moderately (Fig. 39) spaced, forming rhomboids; covering apical half or fully covering cells r 1 and r 2, fully covering cells m 1, m 2, and cu 1 (sometimes restricted to radular areas), m 2 basally, and most of cell cu 2; leaving spinule-free spaces along veins (Fig. 42). Radular spinules sometimes present in r 2 but inconspicuous. Metatibia 0.7 times as long as head width.
Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with short, blunt, almost straight posterior lobe. Paramere, in lateral view (Figs 220 ‾222) 0.7 times as long as proctiger; clavate, strongly expanded apically; anterior margin expanding dorsally and anteriorly in apical third, irregularly concave basally; posterior margin expanding in apical third or quarter, slightly concave subapically, weakly convex in basal half; apex strongly indented in anterior third, with sclerotised ridge in posterior half (Fig. 221); inner surface (Fig. 221) covered with short setae, longer basally and along posterior margin, 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. 292), sclerotised ridge smoothly inward directed, bearing posterior tooth after deep indention. Aedeagus (Fig. 222) complex unipartite; in lateral view, dorsal lobe obovoid; ventral process weakly to strongly upturned, with apical expansion larger than dorsal lobe, irregularly oval, slightly angulate at apex, bearing long, conical tubercle.—Female (Fig. 322). Proctiger, in lateral view, 0.8–0.9 times as long as head width; dorsal outline weakly to strongly concave distal to circumanal ring, apical extension almost straight to sinuous, apex moderately upturned, obliquely rounded, smoothly to strongly 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; basal half of ventral outline strongly expanded, apical half almost straight or sinuous; 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, with setafree patch subapically; in ventral view (Fig. 352), lateral margins evenly, strongly narrowing at half, apical third narrow, weakly narrowing towards rounded apex.

Etymology. Named after its host-plant specific epithet, Andira cujabensis.
Distribution. Brazil: Distrito Federal, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais.
Host-plant. Andira cujabensis Benth. (Leguminosae, Papilionoideae, Aeschynomeneae).
Habitat. Cerrado, dry natural open scrub, gallery forest, transitional forest.
Comments. Mitrapsylla cujabensis sp. nov. resembles M. villosi sp. nov. in the colouration and overall shape, and the paramere with apex strongly indented in anterior third, and anterior margin strongly expanded dorsally; but differs in the sclerotised ridge, in dorsal view, smoothly inward directed, separated from posterior tooth by deep indention (rather than slightly wavy, not separated by deep indention).It also resembles M. itaparica (Crawford) and M. soror sp. nov. (see comments under each species).
