Diagnosis. This species is similar to N. syfaniella but can be easily distinguished by the larger body and long forewings with 24.5 mm of expanse and ca. 3.6 of length/width, while 20 mm of expanse and ca. 3.4 of length/width in N. syfaniella . In the male genitalia, this species has relatively shorter vinculum about 2.66 × valvar length, but about 2.75 × in N. syfaniella .

Description. Male. Forewing 11.8–12.0 mm; wing expanse about 24.8 mm.

Vertex covered with yellow hairs mixed with black; face with smooth yellow scales. Eyes very small, far away to each other dorsally; eye size index about 0.48. Labial palpus short, covered with brownish scales and black hairs; galeae with yellow scales laterally. Antenna slender, black, 36.5 mm, about 3.1 × forewing length. Legs yellow except apical tibiae black; hind tibiae with brown to dark brown long hairs. Thoracic dorsum and tegula yellow to brown, with purple metallic luster. Forewing lanceolate, ground color yellow to brownish; basal 2/3 with four black-margined silver-gray longitudinal striae placed at costal, radial, median and postcubitus veins, not reaching to central fascia; and three black lines placed between above striae; middle part with two black-margined silver-gray transverse fasciae separated a yellow transverse broad band; subapical area with 7 black radial striae reaching outer margin and two triangular spots placed at dorsum and hind angle; cilia dark brown to black, with purple metallic luster; vein R 3 stalked with R 4 at basal 1/3. Hindwing and cilia dark brown to black; Rs stalked with M 1 at basal 3/5. Abdomen black.

Female. Unknown.

Male genitalia. Uncus triangular, with weak median keel. Vinculum moderate in size, about 2.6 × as long as valva. Valva triangular, with blunt apex; inner margins slightly curved, lateral margins straight with a small process basally; sacculus distinctly expanding at basal 1/3, 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, with a pair of distinct anterior angles. Aedeagus slender; basal 1/3 curved dorsally; a rounded dorsal lobe covered with minute spines and a smooth ventral lobe formed an arcuate slender bar; vesica with a pair of angular carinae dorsolaterally. Juxta arrow-shaped; arrow-head long and pointed, lateral arms relatively short.

Holotype. [Hunan] ♁, Mt. Tianpingshan, Badagongshan National Nature Reserve , Sangzhi County, Zhangjiajie City , 2018.IV.26, C.Q. Liao leg. ( HUNAU).

Etymology. The specific epithet refers to the type locality, Mt. Tianpingshan.

Remarks. This species is endemic to Hunan Province, China, and occurs in April.

One DNA barcode of N. tianpingshana sp. nov. is generated, and this sequence is closest to that of six N. bellela specimens (pairwise distances: 0.038 –0.041).
