Description. Adult. Colouration. Head and thorax dirty whitish to ochreous, with dark brown pattern. Vertex with a large patch in the middle of each half, a longitudinal streak along the midline, and each a transverse line near and at the foremargin, respectively. Antennal insertions and eyes with dark margins. Clypeus light in the middle, brown otherwise. Antenna whitish, with apices of segments 4, 6 and 8 as well as entire segments 1, 8 and 9 dark brown. Thorax with a fine dark line in the middle and two broader dark lines sublaterally. Legs dirty whitish with dark brown dots. Forewing semi-transparent, light yellowish with brown dots covering the whole membrane; wing membrane along apical margin light brown, with dark dots denser (Figs 2, 10). Apices of veins Rs, M1+2, M3+4, Cu1a and Cu1b with a dark dot each. Hindwing semi-transparent, whitish. Abdomen yellowish, with dark brown sclerites; terminalia ochreous, brown at base. Young specimens with less extended dark colour.
Structure. Vertex (Figs 38, 52) 1.6 times as wide as long, surface finely punctured; genae evenly curved down; frons small, rectangular. Antenna (Fig. 66) with one subapical rhinarium on each of segments 4, 6, 8 and 9; segments 5 and 7 slightly thinner than other flagellar segments; relative length of antennal flagellar segments = 1.0/ 0.8/ 0.7/ 0.5/ 0.7/ 0.8/ 0.7/ 0.7; segment 3 shorter than segments 4 and 5 together; segment 10 with longer terminal seta about 1.1 times as long as segment and shorter seta about 0.7 times as long. Clypeus strongly subglobular. Pronotum transverse, long, about 5 times as wide as long. Meso- and metascutellum transverse, weakly raised. Metacoxa (Fig. 82) with meracanthus small, tubercular and with a conical, weakly curved membranous process on the trochanteral cavity; metatibia with an open crown of 6 apical sclerotised spurs. Forewing (Figs 2, 10) rhomboidal, apex broadly symmetrically rounded; vein C+Sc concave, slender; vein Rs strongly curved backwards; vein M1+2 curved backwards; membrane semi-transparent; surface spinules (Fig. 24) densely spaced, covering whole wing membrane up to veins; radular spinules forming narrow, ill-defined bands along wing margin in cell m1, m2, and cu1. Terminalia as in Figs 91, 104, 117, 130, 142. Male subgenital plate, in profile, subrectangular with angular dorsal margin. Paramere with posterior lobe; inner face bearing a group of weakly sclerotised thickened setae. Distal portion of aedeagus weakly inflated apically. Female proctiger cuneate, subacute apically. Subgenital plate sparsely pilose ventrally.
