Description. Adult. Colouration. Vertex, pronotum and mesopraescutum yellow with small orange-brown dots. Head and thorax dark brown to almost black ventrally. Vertex and pronotum with each four darker spots. Eyes greyish; ocelli yellowish. Clypeus dark brown to almost black; tip of rostrum black. Antennal segments 1 brown, 2‒7 and 8 basally yellow, apex of 8, 9 and 10 black. Pro- and mesopleurites whitish yellow with fine orange dots. Mesoscutum brown with four longitudinal light lines; mesopleuron with each a dorsal and ventral black dot. Metanotum irregularly dark brown. Legs yellow, femora brown. Forewing ochreous with dark spot at the apex of vein Cu1b (Figs 5, 15). Abdomen yellow to light brown. Dark colour in younger specimens lighter and less expanded.
Structure. Vertex (Figs 43, 57) 2.0 times as wide as long, surface finely punctured; genae evenly rounded down; frons small, rectangular. Antenna (Fig. 71) with one subapical rhinarium on each of segments 4, 6, 8 and 9; segment 9 slightly thicker than segments 8 and 10; relative length of antennal flagellar segments = 1.0/ 0.4/ 0.4/ 0.3/ 0.4/ 0.4/ 0.3/ 0.4; segment 3 longer than segments 4 and 5 together; segment 10 with longer terminal seta about 1.7 times as long as segment and shorter seta about 1.1 times as long. Clypeus weakly flattened, triangular. Pronotum transverse, long, about 5 times as wide as long. Meso- and metascutellum transverse, forming small tubercles. Metacoxa (Fig. 85) with meracanthus flat, small tubercle and long, cylindrical, weakly curved membranous process on trochanteral cavity. Metatibia with an open crown of 5–6 apical sclerotised spurs. Forewing (Figs 5, 15) rhomboidal, apex broadly, slightly asymmetrically; vein C+Sc almost straight, slender; vein Rs weakly curved backwards; vein M1+2 curved backwards; membrane semi-transparent; surface spinules coarse, arranged in irregular hexagonal pattern; radular spinules forming narrow, ill-defined bands along wing margin in cell m1, m2, and cu1. Terminalia as in Figs 96, 109, 122, 135, 145. Male subgenital plate, in profile, subrectangular with angular dorsal margin. Paramere straight, lamellar; inner face bearing a group of strongly sclerotised black pegs. Distal portion of aedeagus weakly inflated apically. Female proctiger cuneate, subacute apically; dorsal margin weakly concave. Subgenital plate sparsely pilose ventrally, subacute apically.

Fifth instar immature (Fig. 156). Colouration. Body brown, membranes light. Dorsal sclerites of head, thorax, wing pads and abdomen brown; base of caudal plate light brown. Antenna ochreous with apex dark brown to black. Apex of rostrum almost black. Apices of tarsi brown.
Structure. Body outline broadly heart-shaped. Antennae 8-segmented with one rhinarium on each of segments 3 and 5, and two on segment 8. Head and wing buds without macroscopic setae dorsally. Thoracic tergites small. Forewing buds large, with short, broadly rounded humeral lobes. Margins of wing buds bearing thick, truncate lanceolate setae (Fig. 168). Legs moderately short and thick with fused tibiotarsus, claws absent; apex of tarsus blunt; tarsal arolium large. Caudal plate angular apically, bearing marginal and a median longitudinal row of dorsal lanceolate setae slightly thicker than those of wing buds; dorsum covered in tubercular microsculpture (Fig. 176). Anus ventral; circumanal ring consisting of one row of elongate pores; relatively small, its width about 0.1 times the distance between its posterior margin and that of caudal plate.
Measurements (in mm) and ratios (1 immature). Body length (BL) 1.50, antenna length (AL) 0.60, forewing pad length (WL) 0.74, caudal plate length (CPL) 0.62, caudal plate width (CPW) 0.74.—BL/body width 1.21, WL/ AL 1.23, CPL/caudal plate width 0.84, CPW/circumanal ring width 7.40.
Etymology. From Latin orientalis = eastern, referring to its occurrence in eastern South America.
Distribution. Brazil (Mato Grosso do Sul, Paraná), Uruguay (Salto).
Host plants. Schinus engleri F.A. Barkley, S. longifolia (Lindl.) Speg. (Anacardiaceae).
