Description. Adult ( Fig. 107View FIGURES 105–110). Colouration. Head and thorax yellow to ochreous; margins of sclerites brown, particularly laterally and ventrally. Vertex with white stripes or dots along coronal suture and white dots on anteorbital tubercles. Genal processes light yellow. Eyes greyish, ocelli orange. Antennal segments 1 and 2 ochreous, segments 3–9 light with dark brown to black apices becoming increasingly longer towards apex; segment 10 almost black. Clypeus yellow; rostrum yellow with black tip. Pronotum with each a submedian, longitudinal white stripe and two sublateral white dots on either side. Mesopraescutum and -scutum with white longitudinal stripes in the middle and submedially, on the latter also sublaterally; mesoscutellum with two white lateral dots. Legs light ochreous, metacoxa brown. Forewing ( Fig. 126View FIGURES 111–133) transparent, colourless to yellowish with dark brown or black dots around radular spinules in cells m 1, m 2 and cu 1, at apex of clavus and at apices of veins Rs, M 1+2, M 3+4, Cu 1a and Cu 1b; veins yellow or light brown. Hindwing whitish, transparent. Abdomen yellow above, whitish below, intersegmental membranes yellow; tergites with each a submedian white dot on either side; spiracles and spiracular sclerites greyish brown. Female proctiger dark brown or black around circumanal ring, at a transverse band distal to circumanal ring and at the tip; dark colour more or less expanded and confluent but always leaving light areas. Tip of female subgenital plate black.

Structure. Head inclined in a 45° angle from longitudinal body axis. Genal processes moderately long, irregularly narrowing towards blunt apex, 0.4–0.7 times as long as vertex along midline ( Fig. 117View FIGURES 111–133). Antenna 1.8–1.9 times as long as head width. Rostrum short, only apical segment visible in profile, 0.4 times as long as head width. Forewing ( Fig. 126View FIGURES 111–133) 2.5–2.9 times as long as head width, 2.2–2.3 times as long as wide, narrowly rounded apically, most strongly curved in cell r 2; pterostigma short, broad at base but narrower than adjacent part of cell r 1; cell cu 1 0.6–0.7 times higher than wide; a few surface spinules present in the middle of cells along apical margin, a few in the middle of cell r 2 and a larger group in the middle of cell m 2 medially, and in cell cu 2 covering most of the surface, otherwise absent. Metatibia 0.6 times as long as head width. Terminalia as in Figs 132View FIGURES 111–133, 135, 151, 152View FIGURES 134–156, 163View FIGURES 157–167. Male proctiger 0.4 times as long as head width, with narrowly triangular posterior lobes basally. Paramere simple, lamellar, in profile with subparallel margins in basal two thirds and slightly expanded in apical third, irregularly rounded apically; inner surface with small, inward or backward directed slerotised tooth; inner surface sparsely covered in long setae. Distal segment of aedeagus weakly expanded in apical quarter with apical hook; sclerotised end tube of ductus ejaculatorius short, weakly sinuous. Female proctiger 1.5–1.6 times as long as head width, dorsal outline sinuous, strongly indented distal to circumanal ring, apex indistinctly obliquely truncate; circumanal ring 0.2 times as long as proctiger. Female subgenital plate 0.6 times as long as proctiger, apex pointed.

Measurements (in mm) and ratios (2 ♂, 2 ♀). Head width ♂ 0.50, ♀ 0.56–0.58; antenna length ♂ 0.92–0.96, ♀ 1.04–1.06; forewing length ♂ 1.26–1.30, ♀ 1.64–1.86; male proctiger length 0.22; paramere length 0.22; length of distal segment of aedeagus 0.24; female proctiger length 0.86–0.90.

Fifth instar immature unknown.

Etymology. Noun in apposition. From Greek μέγας = big and κέρκος = tail, for its long female terminalia.

Distribution. Brazil (BA, MG, PI).

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

Comments. Mitrapsylla megacerca  differs from other copaiba psyllids as indicated in the key. In its green or yellow body colour it resembles M. viridis  , from which it differs in the smaller body dimensions and details of the male and female terminalia.
