Diagnosis. Surface spinules around radular areas of cells m 1, m 2 and cu 1, sometimes much reduced. Paramere, in lateral view, clavate, strongly expanded apically; apex slightly indented submedially; sclerotised ridge in posterior half. Aedeagus complex unipartite; in lateral view, dorsal lobe obovoid; ventral process with apical expansion larger than dorsal lobe.
Description. Colouration. Body with white striped-pattern. Head and thorax light yellow, yellow to orange; genal process lighter than head. Eye grey to dark red; ocelli colourless to orange. Antenna yellow, segments 1–2 concolorous with head. Clypeus concolorous with head, slightly lighter medially; rostrum light yellow to orange. Thorax with margins of sclerites slightly darker. Mesopraescutum sometimes with posterior half irregularly coloured. Forewing yellowish, sometimes darker apically, leaving two colourless semicircles in cells m 1, m 2 and cu 1 apically, yellow around Cu 1b and slightly around M 1+2, M 3+4 and Cu 1a; veins light yellow; pterostigma concolorous or slightly lighter than veins. Hindwing colourless. Fore- and midleg dark yellow, hindleg light yellow. Abdomen light brown to dark yellow; intersegmental membranes light straw-coloured; spiracular sclerites concolorous with abdomen. Male terminalia irregularly dark yellow. Female terminalia irregularly yellow, proctiger darker than subgenital plate, usually brownish apically.
Structure. Body length ♁ 2.4–2.6 mm (2.48± 0.12 mm), ♀ 2.6–2.7 mm (2.66± 0.07 mm) (3 ♁, 4 ♀). Genal pro-cess (Fig. 159) expanded or subconical, irregularly narrowing towards acute, subacute or narrowly rounded apex, 0.5–0.7 times as long as vertex along midline. Antenna 2.3–2.4 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. 189) 2.8–3.0 times as long as head width, 2.2–2.3 times as long as wide, obovoid, slightly narrowly or broadly rounded apically; vein M+Cu 1 0.3–0.4 times as long as Cu 1; ratio a/b 1.6–1.8; ratio c/d 0.7–0.9; ratio e/f 0.8–1.1. Surface spinules moderately spaced, forming rhomboids (Fig. 39); usually absent or much reduced in cell c+sc covering apical half 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). 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 long, weakly tapered, weakly down-curved posterior lobe. Paramere, in lateral view (Figs 271 ‾273) 0.7 times as long as proctiger; clavate, strongly expanded apically; anterior margin expanding in apical half, irregularly concave basally; posterior margin strongly expanding in apical third, weakly to strongly convex in basal two thirds; apex slightly indented submedially, with sclerotised ridge in posterior half (Fig. 272); inner surface (Fig. 272) 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. 309), sclerotised ridge irregularly straight, bearing posterior tooth. Aedeagus (Fig. 273) complex unipartite; in lateral view, dorsal lobe obovoid; ventral process weakly upturned, with apical expansion larger than dorsal lobe, irregularly globular, bearing long, conical tubercle.—Female (Fig. 339). Proctiger, in lateral view, 0.8–0.9 times as long as head width; dorsal outline moderately concave distal to circumanal ring, apical extension sinuous, apex slightly to moderately upturned, smoothly transversally truncate to obliquely rounded; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.5 times as long as proctiger; apex well-developed; basal half of ventral outline strongly expanded, apical half almost straight to slightly convex; covered with medium long setae in median third and ventrally throughout, short and long setae in apical half, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view (Fig. 369), lateral margins evenly, strongly narrowing at apical fourth towards narrow, acutely rounded apex.

Etymology. From Latin soror = sister, referring to its close resemblance to M. itaparica.
Distribution. Brazil: Bahia, Piauí, Roraima.
Host-plant. Adults were collected on Andira paniculata Benth. (Leguminosae, Papilionoideae, Aeschynomeneae) which is a likely host.
Habitat. Cerrado, riverine forest.
Comments. Mitrapsylla soror sp. nov. resembles M. cujabensis sp. nov., M. itaparica (Crawford) and M. villosi sp. nov., in the colouration and overall shape, as well as the paramere strongly expanded apically in lateral view, with sclerotised ridge in about posterior half; but differs from them in the paramere with apex weakly indented in anterior third (rather than straight or strongly indented), and anterior margin weakly expanded dorsally (rather than never or strongly expanded). See comments under M. itaparica (Crawford).
