Fore tarsomere 1 with 1 row of v, and tarsomeres 3–4 with row of curved ventral hairs; hind tarsomere 1 shortened, with upwardly curved spur and 2 strong v at base and 2 rows of v. Relative lengths of tibia and 5 tarsomeres of LⅠ5.0:3.3:2.0:1.7:1.3:0.9; LII6.5:3.8:2.2: 1.9:?:?; LIII7.6:2.0:3.2:2.4:?:?.

Remarks. The new species is similar to N. guangdongensis Wang, Yang & Grootaert from Guangdong Province in having short first flagellomere and 7–8 posterodorsal bristles on hind tibia, but can be separated from the latter by having hind tibia with 1 ad, aedeagus apically with 4 finger-like lateral processes. In N. guangdongensis , the hind tibia has 4 ad, and the aedeagus apically has 2 finger-like lateral processes (Wang, Yang & Grootaert, 2009).
