Diagnosis. This species is similar to N. borealis sp. nov. and N. latirectangula sp. nov. in appearance, and the differences between them are stated in the diagnoses of the N. borealis and N. latirectangula.
Description. Adult (Figs 1, 2). Male wingspan 21.0−28.0 mm.
Head: Vertex black or yellow; frons purple. Eye interocular index 0.40−0.54. Proboscis brown, with yellow scales. Labial palpus 1.1−1.4 × vertical eye diameter; yellow with black hairs.Antenna 3.0−3.4 × length of forewing; scape purplish blue; flagellum grayish brown except dark brown in basal 1/6.
Throax: Mesonotum and tegula golden yellow. Forewing ground color yellowish brown; four grayish brown streaks, edged with black scales, with golden luster: first streak from base to near middle along costal margin, second streak from base to 4/5 of cell along anterior margin, third streak from middle to distal 1/5 of cell along posterior margin, fourth streak from near base to 2/3 of wing along 1A+2A; three black lines: first line from base to 2/5 of wing along R 1, second line from basal 1/3 to 2/3 of cell, third line from base to 2/5 of wing along CuP; fasciae almost straight, inner and outer fasciae silvery gray, with purple luster, medial fascia yellow, edged with dark brown scales; distal 1/4 of wing with nine dark brown stripes radiating along veins from R 2 to CuA 2 respectively; fringe brown. Hindwing grayish brown, with bronzy luster, except light brown between costal margin and Rs; fringe grayish brown. Foreleg yellow ventrally, purplish brown dorsally except tarsus yellow; midleg yellow except tibia purplish brown on dorsal surface; hindleg yellow except tibia bronzy apically. Epiphysis brownish yellow, at basal 2/5 of tibia, not reaching apex of tibia.
Abdomen: Dark brown.
Female wingspan 16.0− 19.5 mm. Antenna 0.80−1.2 × length of forewing, thickened by black scales up to basal 3/5, grayish white distally. Otherwise, similar to male.
Male genitalia (Fig. 27). Socius ovoid, length 2.1 × width. Tegumen without median ridge. Uncus reniform. Valva fused for basal 1/3, broadly rounded at apex, straight on costal margin, slightly sinuate in basal 2/3 on ventral margin; sacculus reaching basal 1/5 of ventral margin. Transtilla with a deeply semicircular emargination anteromedially, subtriangularly produced anterolaterally; median process spiniform, reaching posterior 2/5 of tegumen apically. Vinculum 2.9 × length of valva, broadly rounded anteriorly. Phallus almost straight, same length as vinculum, narrowed apically, with spines preapically (Fig. 27a). Juxta 0.60 × length of phallus; lateral arm 0.18 × length of arrow head.
Female genitalia (Fig. 48). Apophyses posteriores almost same length as apophyses anteriores; apophyses anteriores fused with eighth tergum in posterior 2/5, 2.1 × length of seventh tergum. Eighth tergum triangularly produced anteromedially. Seventh tergum narrowly rounded posteriorly. Vestibulum weakly sclerotized. Ductus bursae 0.33 × length of vestibulum, 0.31× length of corpus bursae. Corpus bursae elongate ovoid.
