Diagnosis. This species is very similar to N. magnifica but can be distinguished by the long forewing (about 4 × as long as width) and very small male eyes (eye size index only 0.4). From the male genitalia of this species, the inter margin of the valva has many serrations, and the arrow-head of the juxta is very slender and pointed.

Description. Male. Forewing about 10.0 mm; wing expanse about 19.0 mm.

Head with raised brownish to dark brown hairs; face with smooth brownish scales. Eyes small, widely separated dorsally; eye size index about 0. 4 in male. Labial palpus moderate in length, with brownish scales and hairs; galeae covered with brown scales laterally. Antenna about 15.8 mm, ca. 1.6 × as long as forewing; basal 1/3 dark brown to black; apical part silvery white. Legs yellow to brown with black tibiae apically; mid- and hind tibiae covered with long brownish hairs. Tegula and thorax (dorsum) dark brown to black. Forewing ground color dark brown basally and black apically; base with a W-shaped yellow stria, proximal line of basal mark not expanding along costal margin; distal line unbroken; zone between medial and distal lines with oval silver-gray spot; middle part with a black-margined transverse central fascia unbroken, distinctly narrow and curved in middle; apical part with 8–10 dark brown to ochreous radial striae along veins mixed black scales among them; cilia dark brown to black with bronze luster; vein R 5 stalked with R 3+4 at middle. Hindwing brown to dark brown except costal area yellow or light brown; cilia brown; Rs stalked with M 1 at middle. Abdomen dark brown to black.

Female. Unknown.

Male genitalia. Uncus triangular, with a distinct median keel. Vinculum moderate in length, about 2.0 times as long as valva. Valva triangular, slightly shorter than uncus with pointed apex; inter margin serrated and lateral margins slightly curved basally; ventral base not fused; suspensorium triangular, anterior part not beyond posterior margin of vinculum. Transtilla narrow in middle; median process short and stout. Aedeagus slender, moderate in length, apical 1/4 concaved dorsally; base of aedeagus swollen; manica with minute spines. Juxta arrow-shaped; arrow-head long and pointed, lateral arms slender.
