Diagnosis. This species is similar to other species of this species group, but can be easily distinguished by the small size of body (wing expanse about 17.4 mm); the forewing ground color is distinctly dark brown with blue metallic luster; and the transverse central fascia of the forewing is obviously narrow in the middle part. In addition, the male genitatia of this new species are similar to N. amatella but has valva distinctly shorter than uncus and relatively longer vinculum about 2.4 times of the valva.

Description. Male. Forewing about 8.0 mm; wing expanse about 17.4 mm.

Vertex covered with black hairs mixed with yellow; face with smooth yellow scales. Eyes very small, far away to each other dorsally; eye size index about 0.4. Labial palpus short, covered with dark brown scales and black hairs; galeae with dark brown scales laterally. Antenna slender, 18.5 mm, about 2.3 × forewing length; basal 1/4 black, apical part light color. Legs yellow, but apical tibiae and whole tarsi dark brown to black; hind tibiae with brown to dark brown long hairs. Thoracic dorsum and tegula black, with blue metallic luster. Forewing lanceolate, ground color dark brown with blue metallic luster; basal 2/3 with four black-margined blue longitudinal striae placed at subcostal, radial, median and postcubitus veins, not reaching to central fascia except the first one; and three black lines placed between above striae; middle part with two black-margined blue transverse fasciae separated a yellow transverse broad band, which slightly narrow at middle; subapical area with 7–8 black radial striae reaching outer margin; cilia dark brown to black; vein R 3 separated with R 4. Hindwing and cilia dark brown to black; Rs stalked with M 1 at basal 1/5. Abdomen dark brown to black.

Female. Unknown.

Male genitalia. Uncus trapezoidal, with weak median keel. Vinculum moderate in size, about 2.4 × as long as valva. Valva triangular, with blunt apex; inner margins almost straight, lateral margins straight with a small process basally; sacculus distinctly expanding at basal part, nearly fused medially; suspensorium nearly quadrate, anterior part not beyond posterior margin of vinculum in ventral view. Transtilla wide laterally and narrow medially; median process short and pointed. Aedeagus slender; basal 1/3 slightly curved dorsally; apical portion near spherical with sclerotized part ventrally and laterally at base, the remaining membranous; vesica with two rows of large spines dorsolaterally. Juxta arrow-shaped; arrow-head very long and slightly pointed, lateral arms relatively short.
