( Figs. 7 View FIGURES 1 – 8 , 15 View FIGURES 13 – 15 )
Type material. Holotype 3, CHINA: Kuerdening, Gongliu (43°28΄N, 82°13΄E), Xinjiang Uygur Autonomous Region, 1500 m, 28 July 1994, leg. Houhun Li and Hongyan Qin, gen. slide No. XYL04118.
Diagnosis: The species is similar to N. echinata Gaedike, 2000 , but differs from it in the fan-shaped gnathos covered with microtrichia in distal 2/5, the juxta consisting of two symmetrical structures, the vinculum deeply concave and U-shaped anteriorly at each side of saccus, and the phallus about equal in length to the valvae. In N. echinata , the gnathos is gradually narrowed distally, the juxta has one M-shaped structure, the vinculum is nearly truncate anteriorly, and the phallus is distinctly longer than the valvae.
Adult ( Fig. 7 View FIGURES 1 – 8 ): Wingspan 13.0 mm. Head pale yellow but dark brown around eyes. Labial palpi with inner side ocherous yellow, outer side dark brown except third segment ocherous yellow at apex. Antennae with scape pale dark brown and flagellar segments pale yellow. Thorax and tegulae dark brown, but tegulae with white on posterior margin. Forewings white, with scattered dark brown scales; dark brown V-shaped pattern from about costal half extending to middle of dorsum, large dark brown spot at base and 1/4 of costal margin respectively; several small conspicuous or inconspicuous spots extending along costal margin and termen; cilia dark brown, speckled with white scales, with three small white strip located at anal corner, 1/3 and 2/3 of termen. Hindwings and cilia dark gray.
Male genitalia ( Fig. 15 View FIGURES 13 – 15 ): Tegumen fused with uncus, anterior margin deeply concave. Uncus concave slightly at middle on caudal margin, forming a small triangular notch, protruding posterolaterally, forming a sclerotized apically acute triangular process, concave inward laterally near apex. Gnathos developed, Vshaped; distal 2/5 broadened, fan-shaped, covered with microtrichia. Subscaphium broad basally, narrow distally. Valvae broad, produced to a heavily sclerotized triangular process; digitiform processes slender at base, broadened gradually to middle; distal half subrectangular, with obtuse-pointed apex slightly exceeding end of valvae. Vinculum with anterior margin deeply concave in U shape at each side of saccus, projecting at middle on caudal margin. Saccus about 0.28x length of valvae, gradually narrowing from base to obtusely rounded apex. Juxta consisting of two sclerotized symmetrical structures, somewhat trapeziform in basal 3/5, subtriangular in distal 2/5, acute at apex. Phallus about equal to length of valvae, articulated at about 2/5; distal 1/6 subtriangular, with a small toothlike process at apex; vesica covered with lots of small lepidotic spines.
Female: Unknown.
Distribution: China (Xinjiang).
Etymology: The specific name is derived from the Latin flabellatus (= flabellate), in inference to the expanded gnathos fan-shaped in distal 2/5.
