Thorax with orangebrown pattern consisting of two sublateral dots on either side of pronotum, two anterior spots on mesopraescutum and four longitudinal bands on mesoscutum. Forewing dirty greyish-yellowish, semi-transparent, with sparse indistinct brown dots mostly in the apical part of wing; apices of veins Rs, M1+2, M3+4, Cu1a and Cu1b brown, sometimes indistinct, darker than surrounding area (Figs 1, 8). Hindwing semi-transparent, whitish. Legs with yellow or brown apical tarsal segment. Abdomen yellowish dorsally, whitish ventrally.
Structure. Vertex (Figs 36, 50) 1.8 times as wide as long, surface finely punctured; genae evenly rounded; frons small, rectangular. Antenna (Fig. 64, 78) with one subapical rhinarium on each of segments 4, 6, 8 and 9; all flagellar segments of similar width; relative length of antennal flagellar segments = 1.0/ 0.6/ 0.5/ 0.6/ 0.6/ 0.6/ 0.4/ 0.5; segment 3 shorter than segments 4 and 5 together; terminal setae about 0.9 and 0.6 times as long as segment 10. Clypeus subglobular. Pronotum transverse, weakly curved, short, about 6 times as wide as long. Meso- and metascutellum transverse, weakly raised. Metacoxa with meracanthus forming medium sized tubercle bearing moderately long, subcylindrical membranous process on the trochanteral cavity. Metatibia with an open crown of 7–8 apical sclerotised spurs. Forewing (Figs 1, 8) rhomboidal, apex broadly, symmetrically rounded; vein C+Sc almost straight, slender; vein Rs weakly curved backwards; vein M1+2 curved backwards; membrane semitransparent; surface spinules (Fig. 22) densely, irregularly spaced, present in all cells, covering membrane up to the veins; radular spinules forming broad, ill-defined bands along wing margin in cell m1, m2, and cu1. Terminalia as in Figs 89, 102, 115, 128, 140. Male subgenital plate, in profile, subrectangular with angular dorsal margin. Paramere bearing obliquely inclined posterior lobe which is posteriorly rounded; inner face bearing a group of weakly sclerotised long, thick setae in apical half.

Legs relatively long and slender with fused tibiotarsus, claws absent; apex of tarsus slender, curved; tarsal arolium very small. Caudal plate truncate apically, bearing marginal slender lanceolate setae and four pointed lanceolate setae on either side; dorsum covered in scale-like microsculpture with just a few setae. Anus terminal; circumanal ring consisting of one row of elongate pores, small; each an additional oval-shaped pore field present on either side of circumanal ring, consisting of several rows of pores (Fig. 172).

Etymology. Named after its host plants Astronium and Myracrodruon, whose Brazilian common name is ‘aroeira’.
Distribution. Brazil (Distrito Federal, Goiás, Mato Grosso do Sul, Minas Gerais, São Paulo).
Host plants. Astronium fraxinifolium Schott, A. graveolens Jacq., Myracrodruon urundeuva Allemão (Anacardiaceae). Some adults were collected on Schinopsis brasiliensis Engl. (Anacardiaceae) which is a likely host. The immatures induce irregular leaf roll galls.
