Female. Body length 7.5–10.3 mm; fore wing 6.2–9.8 mm. Body largely black, following markings creamy yellow: narrow band on inner and outer orbits; a spot on tegulae, paired basolateral roundish spots on T 2, paired basal transverse large spots on T 3 (sometimes connected), and roundish spot on T 6 basally, light yellow spots on T 4-5 usually hidden (Fig. 9 A – D ). Apical 2 / 3 of mid femur, hind femur (basal black), mid and hind tibia reddish; spur brown; squamiform pubescence usually brown (Fig. 9 A, D ). Forewing, except for apical dark area, largely hyaline; pterostigma elongated, its posterior margin parallel to anterior one (Fig. 9 E ). Tarsomere 1 with four long flattened outer spines, slightly widening or almost parallel-sided toward subapex (Fig. 9 F ). POD: OOD = 1.18–1.33; F 1 length 5.78–6.5 times its maximum width. Male.
