White in ground colour; vertical and orbital markings large, blackish brown; coronal suture black; frontal suture bordered with blackish brown band dorsally; frons with two pairs of pale brown markings; gena blackish brown; eye black, IO/D = 1.0; ocelli white, ocellar field black; antennal socket bordered with blackish brown band; postclypeus with seven rows of blackish brown spots, fused with each other ventrally forming large marking, lateral margin of postclypeus blackish brown; anteclypeus blackish brown. Antenna pale brown, scape and pedicel darker. Mouth parts blackish brown; maxillary palpus paler except for 4th segment blackish brown.

Thorax. Prothorax blackish brown. Mesonotum pale brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe of scutum black; anterior margin of scutellum blackish brown; postnotum brown. Metanotum brown, with whitish oval spot on posterior region of each lateral lobe of scutum; anterior margin of scutellum blackish brown. Meso- and metapleurites blackish brown except membranous region white.

Legs. Blackish brown; tibiae paler; fore and middle femora pale brown medially.

Forewing (Fig. 36H). Spots in cell a 1 apparent, distal spot smaller. Opposing spots in cell r large. Proximal band broad in posterior half, broadly interrupted just beyond fork of M + Cu, strongly constricted near anterior part of cell CuA, including broad light area, band in cell CuP, including longitudinal narrow lighter area. Median spots dense, some spots fused with each other and forming larger spots. Distal band broad in cell r 5, fragment of band in cell r 3 rather small. Spot on roof of cell m 3 broad, darker than marginal cloud. Submarginal spots apparent; spot in cell r 5 large and elongate; spot in cell m 3 very small. Marginal clouds broad and dark. Hindwing. Hyaline with faint brown markings in cell CuP; veins brown.

Abdomen. White, each segment with blackish brown band. Terminalia. Clunial arm (Fig. 44A) long, broadened apically, free from membrane at apex, apical tip covered with tiny denticles, postero-dorsal region incised by membrane from dorsal margin to subapical portion. Anterior margin of 8th sternum (Fig. 44C) irregularly indented. Epiproct (Fig. 44A, B) chair-shaped, postero-dorsal margin with semicircular keel-like projection at middle, its posterior margin denticulated; epiproct lobe small, conical. Paraproct (Fig. 44A): ventro-lateral band very short, triangular; distal process short, directed upward. Hypandrium (Fig. 44C): left and right processes conical, directed postero-internally; median tongue circular in ventral view. Phallosome (Fig. 44D, E): pseudoparameres long, needle-like, sinuated, pointed apically. Aedeagus strongly extending anteriorly, projected and pointed posteriorly. Phallobase widest at ventral third, anterior margin almost straight.

Length. B 2.1; FW 3.3; HW 2.4.

Female. Colour and general morphology almost as in male; eye IO/D = 1.6. Genitalia: Egg guide of subgenital plate (Fig. 45A) narrowing to distal quarter, then broadened at distal end, apical margin almost flattened; dorsal surface of egg guide with V-shaped sclerite at middle; posterior margin of body of subgenital plate next to egg guide projected posteriorly. Dorsal valve of gonapophyses (Fig. 45B) with rather short distal process; posterior lobe of external valve not strongly projected posteriorly. Internal plate as in Figure 45C.

Length. B 2.5; FW 3.1; HW 2.4.
