Description. Adult. Colouration. Head and thorax yellow to ochreous. Genal processes light yellow. Eyes reddish or greyish, ocelli orange. Antennal segments 1 and 2 orange, segments 3–8 light with dark brown to black apices becoming increasingly longer towards apex; segments 9 and 10 almost black. Clypeus yellow; rostrum yellow with black tip. Mesopraescutum and -scutum with lighter longitudinal stripes. Legs yellow. Forewing transparent, colourless with dark brown or black dots around radular spinules in cells m 1, m 2 and cu 1 as well as at apex of clavus; veins yellow or light brown ( Fig. 121 View FIGURES 111–133 ). Hindwing whitish, transparent. Abdomen light ochreous, intersegmental membranes yellow. Often with white dots on head, thorax and abdomen arranged in a longitudinal pattern.

Structure. Head inclined in a 45° angle from longitudinal body axis. Genal processes subconical with subacute apex, 0.6 times as long as vertex along midline ( Fig. 112 View FIGURES 111–133 ). Antenna 2.2–2.4 times as long as head width. Rostrum short, apical segment and sometimes apex of median segment visible in profile, 0.4–0.5 times as long as head width. Forewing ( Fig. 121 View FIGURES 111–133 ) 2.8–3.0 times as long as head width, 2.1–2.3 times as long as wide, broadly, evenly rounded apically; pterostigma short, about as wide as or wider than adjacent part of cell r 1 at base; cell cu 1 0.7–0.8 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 0.6–0.7 times as long as head width. Terminalia as in Figs 140, 141 View FIGURES 134–156 , 158 and 166 View FIGURES 157–167 . Male proctiger 0.3 times as long as head width, with narrow, slightly curved posterior lobes basally. Paramere lamellar, hardly widened in apical third without posterior subapical lobe; with small, inwards directed sclerotised tooth apically which is narrowly truncate apically; inner surface moderately densely covered in long setae, with some thicker setae in apical quarter. Distal segment of aedeagus inflated in apical third; distal dilatation irregularly oval, with two apical small teeth; sclerotised end tube of ductus ejaculatorius short, very weakly curved. Female proctiger 1.1 times as long as head width, dorsal outline almost straight or weakly sinuous, apex slightly upturned, blunt; circumanal ring 0.3 times as long as proctiger. Female subgenital plate 0.5 times as long as proctiger, ventral outline weakly curved; sparsely covered in setae, with a seta-free patch in the middle on either side ( Fig. 166 View FIGURES 157–167 ).

Measurements (in mm) and ratios (2 ♂, 2 ♀). Head width ♂ 0.58, ♀ 0.60; antenna length ♂ 1.34–1.38, ♀ 1.30–1.46; forewing length ♂ 1.62, ♀ 1.70–1.80; male proctiger length 0.18–0.20; paramere length 0.200.22; length of distal segment of aedeagus 0.18–0.20; female proctiger length 0.64.

Fifth instar immature unknown.

Etymology. Adjective, feminine form. From Latin borealis = northern, referring to its more northern occurrence compared to that of its close relative M. gloriae   .

Distribution. Brazil (PI).

Host plant, biology and habitat. Adults were collected on Copaifera cearensis Ducke   and C. langsdorffii Desf.   which are likely hosts.—Cerrado.

Comments. Mitrapsylla borealis   differs from the other copaiba psyllids as indicated in the key. It is morphologically most similar to M. gloriae   from which it differs in details of the male and female terminalia (see comments under M. gloriae   ).
