( Figs. 5 , 13 , 19 ) Type material. Holotype 3, CHINA : Xunyangba, Ningshan (33°19΄N, 108°20΄E), Shaanxi Province, 1360 m , 28 June 2007 , leg. Haili Yu, gen. slide No. XYL08020. Paratypes : 1 3, 2 ƤƤ, 28 June–3 July 2007 , same data as for holotype . Diagnosis: The species resembles N. gerasimovi in appearance, but can be separated easily from it by the gnathos having two small toothlike processes at apex, the valvae subtriangular in distal 1/3, and the phallus not bifurcated distally. In N. gerasimovi , the gnathos terminates in a small apex, the valvae are subrectangular in distal 1/3, and the phallus is bifurcated in distal 1/3. Adult ( Fig. 5 ): Wingspan 9.0–11.0 mm. Head ocherous yellow. Inner side of labial palpi ocherous yellow; outer side dark brown except third segment ocherous white at apex. Antennae ocherous yellow. Thorax and tegulae dark brown except tegulae ocherous white on posterior margin. Forewings ocherous white, with scattered dark brown scales; costal margin with seven dark brown spots, the third one largest, extending from costal 1/2 to midwing; large dark brown spots located at middle of anal fold and at subapex of the wing; cilia grayish ocherous, tinged with dark brown. Hindwings and cilia gray. Male genitalia ( Fig. 13 ): Tegumen fused with uncus, concave anteriorly. Uncus slightly concave at middle on posterior margin. Gnathos curved, elbow-shaped, basal 1/2 broad, somewhat rectangular; distal 1/2 narrow, with two small toothlike processes at apex. Subscaphium with basal half broad, cup-shaped, distal half narrow, subrectangular. Valvae strongly sclerotized, subtriangular in distal 1/3, obtusely pointed at apex; digitiform processes with apex obtusely pointed, obviously exceeding tip of valvae. Vinculum with anterior margin deeply concave inward on each side of saccus, caudal margin somewhat W-shaped. Saccus about 0.60x length of valvae, apex blunt. Juxta weakly sclerotized ventrally, arcuate; well sclerotized dorsally, composed of two symmetrical, somewhat quadrate plates. Phallus about 1.34x length of valvae, broadly oblique apically, articulated at about 1/3; cornuti composed of some microtrichia. Female genitalia ( Fig. 19 ): Sternum VIII weakly sclerotized, somewhat shield-shaped, anterior margin broadly rounded, posterior margin almost straight. Ostium bursae sclerotized, shield-shaped dorsally, subtriangular ventrally. Antrum inconspicuous. Ductus bursae basally sclerotized, about 1.6x length of apophyses anteriores; a spiculose ring at 1/2, weakly sclerotized, covered with small lepidotic spines. Distribution: China (Shaanxi). Etymology: The specific name is derived from the type locality, Ningshan.
