Diagnosis. This species is similar to N. orientana Park, 2005 in both superficial and male genital characters, but it can be distinguished from the latter by the uncus longer than the gnathos in the male genitalia, and the corpus bursae with two signa in the female genitalia; in N. orientana , the uncus is shorter than the gnathos, and the corpus bursae has a single signum.

Description. Adult ( Fig. 14 View FIGURES 12-17 ) wingspan 21.0–26.0 mm.

Head dark brown, mixed with pale orange scales. Antenna with scape elongate, dark brown; flagellum pale orange, annulated with dark brown dorsally. Labial palpus pale orange mixed with dark brown scales; second segment thickened; third segment slender, shorter than second segment.

Thorax and tegula dark brown, with pale orange scales. Forewing with costal margin slightly arched, apex triangularly produced, termen broadly concave; ground color dark brown mixed with orange white, except ochreous yellow from distal 1/4 to apex below costal margin, with dense yellowish-brown scales forming stripes along veins; costal margin with three dark brown spots, spaced along distal 1/4; discal stigma small, sub-triangular, dark brown; discocellular stigma inverted L-shaped, dark brown, edged with white scales; subterminal line white, sub-crescent, from beyond distal 1/4 of costal margin to about M 3 before termen; terminal line dark brown; fringe dark brown, mixed with dark yellowish brown; basal line white. Hindwing with costal margin almost straight, apex sharply acute, termen sinuate; ground color greyish orange except dark brown mixed with orange white distally, with yellowish-brown scales along veins and before termen; area between 3A and dorsum dark brown mixed with white scales; discocellular stigma narrow, creamy white; subterminal line white, wavy, extending from distal 1/4 of costal margin to tornus; terminal line dark brown; fringe dark yellowish brown, mixed with dark brown; basal line white. Legs dark brown with pale orange scales; mid and hind tibiae covered with dense long scales; hind tarsus with first tarsomere roughly scaled.

Male genitalia ( Fig. 27 View FIGURES 24-30 ). Uncus large rectangular, longer than gnathos, slightly arched apically, with a few setae distally. Gnathos with basal plate ovate and obtusely rounded posteriorly; median process gently bent, wide at base, narrowed to about middle, slender distally. Valva sub-rectangular, setose distally; sacculus uniform, about half length of ventral margin of valva. Juxta with basal part sub-quadrate, concave laterally, produced to a digitate process antero-medially, distal part membranous; lateral process anterior to middle, about 1/4 length of juxta, narrowed at base, broadened toward obtuse and setose apex. Vinculum broad, obtuse anteriorly. Aedeagus shorter than valva, uniform, curved ventrad at basal 1/3 and dorsad at basal 2/3.

Female genitalia ( Fig. 35 View FIGURES 35-38 ). Abdominal sternite VIII shallowly concave at middle on posterior margin. Apophyses anteriores about 3/4 length of apophyses posteriores, with a small furcation before middle. Ductus bursae longer than corpus bursae; ductus seminalis much slender, arising from posterior 1/3 of ductus bursae. Corpus bursae oblong; with two signa: one horizontally linear, posterior to middle, another smaller, sub-ovate, at anterior 1/3.

Distribution. China (Guizhou, Yunnan).

Etymology. The specific epithet is derived from the Latin grand- (= large) and uncus, referring to the large uncus in the male genitalia.
