(Figs. 23–28)
Diagnosis. This small species is characterized by an elongate epiproct that tapers to a blunt point apically. Additionally, the outer lobe of the two-lobed paraprocts forms a distinct hook apically that recurves dorsally.
Male. Forewing length 3.8–4.5 mm, hindwing length 3.3–3.8 mm. Head and appendages dark brown; compound eyes dark. Thorax brown; wings subhyaline; legs brownish yellow. Abdomen brown with pale hairs.
Terminalia (Figs. 23–27): Tergum nine weakly sclerotized with anterior and posterior margins nearly parallel. Sternum nine with robust vesicle, narrow basally and swollen apically, much longer than half hypoproct length; hypoproct suboval, broad basally and gradually tapering posteromedially to a small tip. Tergum ten slightly sclerotized, except posteromedially where it is heavily sclerotized, a shallow median concavity present bearing several tiny, black spines anteriorly, posteriorly on either side of epiproct tip are two lateral humps topped by a thick, black spine and several tiny hairs. Cercus sclerotized, heavily so apicolaterally, with a large, apical, laterally directed spine. Epiproct elongate and tapering apically to a blunt point; dorsal sclerite with two darkly sclerotized loops medially; ventral sclerite sclerotized, ventrally broad at base and narrowing toward apex, with several black spines ventrally. Paraproct with outer lobe distinctly sclerotized to form a hook apically; inner lobe slightly sclerotized, nearly quadrangular, with a membranous area proximally with rows of hairs.
Female (Fig. 28). Forewing length 5.0 mm, hindwing length 4.3 mm. Sternum 7 heavily sclerotized with Y-shaped pregenital plate, distal part overlapping anterior margin of subgenital plate of sternum 8. Subgenital plate sclerotized, with anterior portion produced anteriorly, posterior margin straight, covering a darkly sclerotized, triangular plate posteriorly. Cercus membranous.
Type Material. Holotype: male (IZCAS), CHINA: Xinjiang, Hejing, 42o31'N, 86o35'E, 2,600 m, 1958. VII. 28, Ch. Li. Paratypes: 1 male (IZCAS), Xinjiang, Wukugonglu, Tianshanbeipo?, 1965. VI. 19, 1,600 m, Sh. Wang; 4 males, (IZCAS), Xinjiang, Wukugonglu, Tianshanbeipo?, 1960. VI. 14, 1,600 m, Sh. Wang; 2 males (IZCAS), Xinjiang, Buerjin, 47o70'N, 86o92'E, 480 m, 1960. VIII. 25, Sh. Wang; 1 male (IZCAS), Xinjiang, Hejing, 42o31'N, 86o35'E, 2,600 m, 1965. VI. 18, Sh. Wang.
Distribution. China (Xinjiang).
Etymology. The species is named after the collector, Shuyong Wang.
Remarks. The new species is related to N. jilinensis Zhu & Yang from Jilin by the dorsal sclerite of the epiproct forming a semicircular structure and by a similar cercus. It may be separated from N. jilinensis by the sclerotized apical hook of the paraproct. In N. jilinensis, the paraproct is slightly sclerotized with two protrusions apically (Zhu and Yang 2003).
