Material examined. Hubei: Luotian County, Tiantangzai national forest Park , 31.11°N, 115.73°E, 946m, 23–27 June 2009, X. Xu & H.J. Xie leg., 3MM and 68FF (CBEE); Hainan: Bawangling Mountain National Nature Reserve , 19.13°N, 109.10°E, 300m, 21 October 2009, H. Yu leg., 9MM and 2MM ( CBEE) .

Diagnosis: This species is similar to N. compta and N.nitens in having simple paracymbium without branches distally, distal suprategular apophysis with hook-shaped tip of dorsal arm and membranous ventral tip, and the large semicircular atrium opening, but can be distinguished from them by the following characters: 1, the terminal apophysis long, slender, with moderately membranous tip in N. emphana , but short, wide, with strongly chitinous tip in N. compta and N.nitens ; 2, the distal blunt chitinous apical lobe significantly larger than the spermduct-tooth in N. emphana , but almost same in N. compta and N.nitens ; 3, the semicircular opening of atrium with anterior margin notched mesally in N. emphana , but not in N. compta and N.nitens ( Figs 27–28 , 29 C–E, 21–22, 23C–E, 47– 48, 49C–E).

Description: See Van Helsdingen (1969).

Distribution: China (Heilongjiang, Jilin, Niaoning, Neimenggu, Shanxi, Beijing, Henan, Hubei, Hunan, Anhui, Guizhou, Sichuan, Hainan, Yunnan, Hebei); Europe, Russia, North Korea, Japan ( Fig. 69 ).
