Diagnosis. Body usually darker ventrally. Surface spinules absent or much reduced around radular areas of cells m 1, m 2 and cu 1. Paramere, in lateral view, irregularly lamellar; anterior margin weakly sinuous; posterior margin rounded in apical third, strongly expanded in basal two thirds; apex strongly rounded. Aedeagus complex tripartite; in lateral view, lateral lobule subequal in size with median lobule, subobovoid; ventral process with apical expansion subequal in size with dorsal lobe.
Description. Colouration. Body with white striped-pattern; variation: vertex with stripe along posterior margin weak when present; older specimens with markings with dark outline. Head and thorax yellowish-brown to ochreous. Gena usually darker to brown anteriorly, slightly darker to dark brown ventrally; genal process lighter than vertex, brownish. Eye red to dark red; ocelli colourless to orange. Antenna yellow to light brown, segments 1–2 concolorous with head. Clypeus brown, lighter medially and darker along edges; rostrum light yellow to dark yellow. Thorax usually slightly darker to dark brown ventrally, usually with margins of sclerites darker. Forewing colourless to yellowish, sometimes slightly darker around Cu 1b; veins light yellow to yellowish-brown, usually darker apically; pterostigma concolorous, lighter or darker than veins. Hindwing colourless. Legs light to dark yellow with femora light to dark brown, except apically, sometimes pro- and mesotarsi slightly darker.Abdomen light brown to medium brown, usually darker ventrally; intersegmental membranes light straw-coloured; spiracular sclerites concolorous or slightly darker than tergites. Male terminalia light brown to dark brown, proctiger and paramere usually lighter. Female terminalia irregularly light brown to dark brown, proctiger usually brown apically and subgenital plate brown basally.
Structure. Body length ♁ 2.2–2.6 mm (2.43± 0.12 mm), ♀ 2.5–2.7 mm (2.61± 0.07 mm) (5 ♁, 5 ♀). Genal pro-cess (Fig. 143) expanded, irregularly narrowing towards broadly or narrowly rounded apex, 0.6–0.7 times as long as vertex along midline. Antenna 1.9–2.5 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 0.7 times longer than median segment. Forewing (Fig. 173) 2.8–3.1 times as long as head width, 2.1–2.4 times as long as wide, obovoid, 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 0.5–0.8. Surface spinules covering cells r 1 and r 2 apically, absent or much reduced around radular areas of cells m 1, m 2 and cu 1, covering 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 0.6–0.7 times as long as head width.
Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with long, blunt, strongly downcurved posterior lobe. Paramere, in lateral view (Figs 223 ‾225) 0.9 times as long as proctiger; irregularly lamellar; anterior margin weakly sinuous, sometimes almost straight before apex; posterior margin rounded in apical third, strongly expanded in basal two thirds; apex strongly rounded, with sclerotised ridge posteriorly (Fig. 224); inner surface (Fig. 224) covered with long setae, longer basally and along posterior margin, with row of thick setae along apical anterior margin, group of thick setae below sclerotised ridge, and several stout setae on apical posterior margin; in dorsal view (Fig. 293), sclerotised ridge slightly wavy, blunt, bearing posterior tooth. Aedeagus (Fig. 225) complex tripartite; in lateral view, dorsal lobe with slightly prominent median lobule; lateral lobule subequal in size with median lobule, subobovoid; membranous pouch rather broad; ventral process strongly upturned, with apical expansion subequal in size with dorsal lobe, oval, bearing long, conical tubercle.—Female (Fig. 323). Proctiger, in lateral view, 1.0 times as long as head width; dorsal outline weakly to moderately concave distal to circumanal ring, apical extension almost straight to sinuous, apex strongly upturned, strongly obliquely truncate; circumanal ring 0.2–0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.5–0.6 times as long as proctiger; apex well-developed; ventral outline almost straight to slightly sinuous, sometimes slightly notched subapically; 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 seta-free patch subapically; in ventral view (Fig. 353), lateral margins evenly, strongly narrowing at about half towards broad, subtruncate apex.
Measurements (in mm) (3 ♁, 3 ♀). HW ♁ 0.56–0.63 (0.59±0.03), ♀ 0.64–0.69 (0.66±0.03); AL ♁ 1.18–1.37 (1.29±0.1), ♀ 1.47–1.61 (1.55±0.07); LAB2 ♁ 0.14–0.15 (0.14±0.01), ♀ 0.15–0,16 (0,16±0); LAB3 ♁ 0.09 (0.09±0), ♀ 0.09–0.10 (0.10±0.01); FL ♁ 1.69–1.76 (1.73±0.04), ♀ 1.99–2.06 (2.01±0.04); TL ♁ 0.37–0.41 (0.39±0.03), ♀ 0.42–0.45 (0.43±0.02); MP 0.25–0.27 (0.26±0.01); PL 0.23–0.25 (0.24±0.01); DL 0.28–0.30 (0.29±0.02); FP 0.66–0.67 (0.67±0.01).
Etymology. From Latin cuspidatus = pointed, referring to the paramere shape.
Distribution. Brazil: Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, S„o Paulo.
Host-plant. Machaerium hatschbachii Rudd, M. hirtum (Vell.) Stellfeld and M. paraguariense Hassl. (Leguminosae, Papilionoideae, Aeschynomeneae). Adults were also found on Machaerium nyctitans (Vell.) Benth., which is a likely host.
Habitat. Araucaria forest, Atlantic forest, edge of Atlantic forest around coffee plantation mixed with pastures, Cerrado, gallery forest, mixed Atlantic/ Araucaria forest, parks, rupestrian grassland.
Comments. Light specimens of M. cuspidata sp. nov. resemble Mitrapsylla pallida sp. nov. in the overall shape as well as the paramere irregularly lamellar in lateral view, with apex directed posteriorly; but differs in the longer genal process, the paramere with apex strongly rounded (rather than slightly notched anteriorly) and the surface spinules absent or much reduced around radular areas of cells m 1, m 2 and cu 1 (rather than fully covering all cells), leaving spinule-free spaces along veins (rather than covering cells up to veins) and the aedeagus tripartite.
