Forewing length: 8–10 mm in male, 8.5–10.5 mm in female. Head: white; labial palpus up-curved, brownish white; male antennae plumose, and female filiform. Thorax: patagium and tegula white. Abdomen: covered with white scales, segments A 1 and A 2 with grayish white. Forewing ground color white, with dark-brown band on the costal margin in the antemedial and basal line regions; antemedial line present, a brown dot at Cu 2 -1 A + 2 A in male, a thin rust-colored line in female; medial line absent; postmedial line double, rather dark brown, wavy, area between two lines filled with brownish red; subterminal line varies from dark brown to blackish brown; terminal and subterminal lines regions deeply gray in male, female same as ground color. Hindwing white; antemedial line rust-colored, discontinuous; postmedial line double, dark brown to dark reddish brown, wavy, prominently excurved at M 3, area between two lines filled with light brownish red, and with outer light brownish-red line in female; marginal shade brownish red, mixed with black in posterior half, but very thin or absent before Rs in male; Rs and M 3 with tails at outer margin; terminal line present as a small dot at M 3 - Cu 1 in female, but in male a short, slender, distinct black strip.</p><p><i>Male genitalia</i> (Fig. 15). Uncus hook-shaped, apex pointed, strongly sclerotized. Tegumen triangular approximately 2 × length of uncus. Gnathos sclerotized, trident-shaped, median process longest. Valva bar-shaped, covered with dense hair; sacculus arcuate, about 2 / 5 as long as valva; editum-costa complex bifurcate, one branch short and conical, other long and bar-shaped, and extending to the anterior of cucullus; cucullus, apex bluntly rounded; costa with weak bulge in middle; cucullus rounded, apex slightly enlarged. Juxta membranous, horseshoe-shaped, with a narrow V-shaped thin area at centre. Vinculum V-shaped. Saccus small and V-shaped. Aedeagus short and wide, slightly curved, cylindrical, with a small protuberance at middle coecum about 1 / 3 × the length of aedeagus. Vesica membranous, with a fruit-knife-shaped cornutus, and diverticula with graniculi.</p><p><i>Female genitalia</i> (Fig. 22). Papillae analis conical, covered with short setae. Apophysis posterioris slender, approximately 1.5 × length of apophysis anterioris. Ostium bursae like an inverted triangle, strongly sclerotized. Ductus bursae membranous, about 3 / 10 as long as corpus bursae. Corpus bursae membranous, densely covered with graniculi; tubular part funnel-shaped, gradually narrowing, with two small rectangular signa; globular part oval, with a large, sclerotized, durian-shaped signum.</p><p><b>Distribution.</b></p><p>China (Shaanxi, Jiangxi, Chongqing, Sichuan) (Fig. 40).</p><p><b>Etymology.</b></p><p>The species name <i>atromarginata</i> is from the Latin words “ atro ” and “ marginata ”, meaning black and margin and referring to the terminal subterminal line regions of the forewing which are covered with black patches.</p><p><b>Remarks.</b></p><p>Chu et al.
