Brazil : Santa Catarina , 2 ♂ , 3 ♀ , same data as holotype but ( MZSP , NHMB , dry and slide mounted) ; 1 ♂ , same but Ibama station , S28°05.7’ W49°30.4’ , 1610 m , 21.i.2016 , #181(2) ( NHMB , dry mounted). Description. Adult. Colouration. Body dark brown to almost black. Vertex very dark purplish. Eyes and ocelli grey. Antennal segments 1, 8‒10 black, 2 yellow, 3‒7 yellow to light brown with apices of segments 4 and 6 dark brown. Pronotum dark purplish along fore margin. Thorax with some light dots laterally. Forewing dark brown, with narrow stripe along C+Sc and around apex of clavus light ( Fig. 12 ). Hindwing semi-transparent, whitish. Legs with ochreous tibiae and tarsi. Abdomen with light narrow longitudinal median band ventrally; intersegmental membranes light. Younger specimens lighter with more expanded light pattern and brown forewings. Structure. Vertex ( Figs 40 , 54 ) 1.5 times as wide as long, surface finely punctured; genae evenly rounded; frons small, rectangular. Antenna ( Fig. 68 ) with one subapical rhinarium on each of segments 4, 6, 8 and 9; segment 9 slightly thicker than other flagellar segments; relative length of antennal flagellar segments = 1.0/ 0.5/ 0.4/ 0.4/ 0.5/ 0.5/ 0.4/ 0.4; segment 3 longer than segments 4 and 5 together; terminal setae about 1.1 and 0.4 times as long as segment 10. Clypeus subglobular. Pronotum transverse, very weakly curved, short, about 5 times as wide as long. Meso- and metascutellum transverse, weakly raised. Metacoxa ( Fig. 83 ) with meracanthus forming relatively flat tubercle bearing long, subcylindrical weakly curved membranous process on the trochanteral cavity. Metatibia with an open crown of 6 apical sclerotised spurs. Forewing ( Fig. 12 ) rhomboidal, apex narrowly, asymmetrically rounded; vein C+Sc weakly concave, slender; vein Rs almost straight, though weakly curved backwards; vein M1+2 curved backwards; membrane almost opaque; surface spinules mostly wanting, present as one or two lines along the veins ( Fig. 26 ); radular spinules forming broad, ill-defined bands along wing margin in cell m1, m2, and cu1. Terminalia as in Figs 93 , 106 , 119 , 132 , 143 . Male subgenital plate, in profile, subrectangular with slightly concave dorsal margin. Paramere straight, lamellar; inner face bearing a group of strongly sclerotised peg setae in apical half. Distal portion of aedeagus weakly inflated apically. Female proctiger cuneate, subacute apically. Subgenital plate sparsely pilose, subacute apically. Measurements (in mm) and ratios ( 1 ♂ , 1 ♀ ). Head width (HW) 0.84–0.94 (0.89±0.07), antenna length (AL) 0.80–0.92 (0.86±0.08), forewing length (WL) 1.98–2.36 (2.17±0.27), metatibia length (TL) 0.46–0.58 (0.52±0.08), male proctiger length (MP) 0.42, paramere length 0.30, length of distal segment of aedeagus 0.28, female proctiger length (FP) 0.98.—AL/HW 0.95–0.98 (0.97±0.02), WL/HW 2.36–2.51 (2.43±0.11), WL/forewing width 1.90– 1.93 (1.92±0.02), metafemur length/TL 0.66–0.78 (0.72±0.09), TL/HW 0.55–0.62 (0.58±0.05), MP/HW 0.50, FP/ HW 1.04, FP/circumanal ring length 4.45, FP/subgenital plate length 1.40.

Adults were collected on Schinus engleri F.A. Barkley (Anacardiaceae) which is a likely host.
