Diagnosis. This species is very similar to N. aurifera but can be distinguished by large eyes (eye size index about 7.1), long labial palpus with dense long hairs (more than the vertical diameter of compound eyes), and transverse central fascia with a wide costal half about twice the width of the dorsal half.

Description. Male. Forewing about 9.7 mm; wing expanse about 20.2 mm.

Vertex covered with brownish to black hairs; face with dark yellow scales medially and yellow hairs around compound eyes. Eyes very large, close to each other dorsally; eye size index about 7. Labial palpus very long, more than vertical diameter of compound eyes, covered with dense yellow brown and black hairs; galeae with brownish scales laterally. Antenna slender, about 25.0 mm, 2.6 × forewing length; scape brownish with golden metallic luster; basal 1/3 black and most remaining apical segments light brown. Legs dark brown to black; hind tibiae with brown to dark brown long hairs. Thoracic dorsum and tegula brown to dark brown, with bronze metallic luster. Forewing lanceolate, ground color dark brown to black, with bronze metallic luster; middle part with a yellow transverse fascia, costal half about twice width as dorsal half; subapical area scattered with some brown scales; cilia dark brown to black with bronze metallic luster. Hindwing and cilia dark brown to black, costal area slightly light color. Abdomen dark brown to black.

Female. Unknown.

Male genitalia. Uncus near semicircle, with weak median keel. Vinculum relatively slender, about 3.2 × as long as valva; posterior margin distinctly arcuate. Valva near trapezoid in ventral and lateral views, with pointed apex, far beyond uncus; inner margins slightly concaved, lateral margins distinctly concaved; sacculus expanding at apical 1/3 with a small process, basal part almost fused medially; suspensorium nearly trapezoid, anterior part beyond posterior margin of vinculum in ventral view. Transtilla approximately equal in width; median process short and blunt. Aedeagus slender; apical 2/5 curved dorsally; apex with a broad smooth lobe ventrally and a pair of microechinate lobes laterally; vesica with a pair of long, strongly sclerotizated lamellates dorsolaterally and two rows of spines dorsally. Juxta arrow-shaped; arrow-head broad, lateral arms slender.
