Material examined. Hubei: Luotian County, Tiantangzai national forest Park , 30.41°N, 102.77°E, 618m, 20.vii. to 7.viii.2009, X. Xu & H.J. Xie leg., 32MM and 137FF (CBEE); Hainan: Bawangling Mountain National Nature Reserve , 19.13°N, 109.10°E, 300m, 21.x,2009, H. Yu leg., 4MM and 6FF ( CBEE) .

Diagnosis: This species is similar to N. birmanica in having a small paracymbium without broad and flattened distal arm, the simple embolic and the trapeziform atrium opening, but can be distinguished from the latter by the long and slender terminal apophysis with knob-shaped tip, the significantly long vulva (the length about 1.5 times width), the copulatory grooves with two and a half coils (with one and a half in N. birmanica ) ( Figs 10–11 , 12 C–E, 33–34, 35C–E).

Description: See Van Helsdingen (1969).

Distribution: China (Heilongjiang, Jilin, Shanxi, Beijing, Hebei, Henan, Hubei, Hunan, Anhui, Yunnan, Sichuan, Zhejiang, Fujian, Jiangxi, Shan-xi, Guizhou, Jiangsu, Hainan); Russia, Japan, North Korea ( Fig. 69 ).
