Description. Adult. Colouration. Head and thorax brown. Vertex with whitish, partially interrupted stripes surrounding each half and white anteorbital tubercles. Genal processes ochreous with white, transverse stripe at base. Eyes dark greyish, ocelli orange. Antennal segments 1 and 2 ochreous, segment 3 light brown, segments 4–8 light brown with dark brown to black apices becoming increasingly longer towards apex; segments 9 and 10 almost black. Clypeus yellow; rostrum yellow with black tip. Pronotum with two white submedian stripes and each two white sublateral dots. Mesopraescutum with white longitudinal median stripe, a white lateral c-shaped stripe and each two sublateral dots. Mesoscutum with one median and each two submedian longitudinal white stripes as well as a lateral dot. Mesoscutellum with each a sublateral longitudinal, slightly curved white stripe. Metathorax mostly yellow; metascutellum with median white longitudinal white stripe. Legs yellow; femora partly and pro- and mesotarsi entirely dark brown to almost black. Forewing transparent, membrane ochreous to light brown, veins brown with dark brown or black dots around radular spinules in cells m 1, m 2 and cu 1 as well as at the apices of veins Rs, M 1+2, M 3+4, Cu 1a and Cu 1b and the apex of clavus (Fig. 120). Hindwing transparent, very slightly brownish. Abdomen almost black, intersegmental membranes dirty yellowish or light brown. Male terminalia irregularly brown; female terminalia dark with irregular light patches. Light colour in younger specimens more expanded.
Structure. Head inclined in a 45° angle from longitudinal body axis. Genal processes irregularly narrowing towards blunt apex, 0.7–0.9 times as long as vertex along midline (Fig. 111). Antenna 2.9–3.1 times as long as head width. Rostrum short, only apical segment visible in profile, 0.3–0.4 times as long as head width. Forewing (Fig. 120) 2.8–3.1 times as long as head width, 2.1–2.3 times as long as wide, broadly, evenly rounded apically; pterostigma moderately long, broad at base; cell cu 1 0.9–1.0 times higher than wide; surface spinules much reduced, present in apical half of cell r 1, in the middle of cells r 2, m 1, m 2 and cu 1 along wing margin, and in cell cu 2 leaving broad spinule-free stripes along the veins. Metatibia 0.6 times as long as head width. Terminalia as in Figs 129, 134, 136, 138, 139, 157. Male proctiger 0.4 times as long as head width, with narrow, slightly curved posterior lobes basally. Paramere lamellar; apex ending in a single, slightly forward directed slerotised tooth; inner surface sparsely covered in long setae. Distal segment of aedeagus inflated in apical quarter, bearing two long spines at the base of apical dilatation; sclerotised end tube of ductus ejaculatorius short, sinuous. Female proctiger 1.3–1.5 times as long as head width, dorsal outline weakly sinuous, apex obliquely truncate; circumanal ring 0.2 times as long as proctiger. Female subgenital plate 0.6 times as long as proctiger, apex upturned.
Measurements (in mm) and ratios (4 ♂, 3 ♀). Head width ♂ 0.88–0.90, ♀ 0.94–1.00; antenna length ♂ 2.64– 2.76, ♀ 2.84–2.92; forewing length ♂ 2.44–2.52, ♀ 2.70–3.06; male proctiger length 0.34–0.38; paramere length 0.30–0.34; length of distal segment of aedeagus 0.36–0.38; female proctiger length 1.24–1.48.
Fifth instar immature (Fig. 168). Colouration. White, antenna yellowish with apices of flagellar segments brown. Tibiae and tarsi greyish brown.
Structure. Body 1.8 times as long as wide. Antenna 8-segmented, 2.1–2.2 times as long as forewing pad, which has 10 or more short setae dorsally. Circumanal ring relatively large, consisting throughout of several rows of pores.
Measurements (in mm) and ratios (2 immatures). Body length 2.28–2.32, antenna length 1.32–1.36.
Etymology. Adjective, feminine form. From Latin adustus = browned, scorched, dusky, swarthy, dark for its dark body colour.
Distribution. Brazil (CE, MG, PR, RJ), Paraguay.
Host plant, biology and habitat. Copaifera langsdorffii Desf., C. trapezifolia Hayne. —Eggs are laid in rows into the leaf buds. The immatures are free-living.—Cerrado, Atlantic forest, transition from riparian to cerrado vegetation.
Comments. Mitrapsylla adusta differs from other copaiba psyllids as indicated in the key. It is closest to M. repens from which it differs in the adults in the slightly larger body dimensions, the slightly longer genal processes which are a bit more pointed apically, the forewing membrane which is ochreous to light brown in mature specimens rather that greyish, the apex of the paramere which forms a small hook, and the apical quarter of the distal aedeagal segment which is strongly inflated and bears two large spines. Apart from the slightly longer proctiger in M. adusta, no differences could be found in the female terminalia between M. adusta and M. repens.
