Forewing about 8.5 mm; wing expanse about 16.7 mm.</p><p>Vertex densely covered with brownish to brownish-red hairs; face with dark brown scales medially and brownish hairs around compound eyes. Eyes relatively large, eye size index about 1.3. Labial palpus relatively long, covered with brownish scales and dark brown hairs; galeae with yellow scales laterally. Antenna slender, about 22.4 mm, 2.6 × forewing length; scape brown with purple metallic luster; basal 2/5 black and most remaining apical segments light brown. Legs black with brownish inner surface; basal part of tibiae and tarsi yellow. Thoracic dorsum brown to black and tegula black, both with bronze metallic luster; thoracic sternum yellow. Forewing lanceolate, ground color dark brown to black, with purple metallic luster; middle part with a yellow transverse fascia, approximately equal in width but slightly narrow at anterior margin; subapical area scattered with a lot of yellow scales; cilia dark brown to black with bronze metallic luster.

Transtilla distinctly wider in lateral part; median process moderate and pointed. Aedeagus slender; apical 2/5 very curved dorsally; apex divided into two slender lobes dorsally and ventrally; vesica with two rows of three small spines dorsolaterally.
