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).
