YS 17092 ♂, YS17155 ♀; Hainan Province : 1♀, Ying- geling, 270 m, 10.XI.2016, leg. Xia Bai, Shuonan Qian & Wanding Qi, slide No. YS17154; Hong Kong: 1♀ , Dagangzai, Sai Kung , 140 m, 15.IV.2007, leg. Houhun Li et al., slide No. YS 18076 ; 1♀, Nam Chung , 135–150 m, 18.IV.2007, leg. Houhun Li, et al., slide No. LSR13149 .

Diagnosis. Adult ( Fig. 8 ) wingspan 13.0–16.0 mm. This species is superficially similar to N. abunda sp. nov. and N. apiculata sp. nov. It differs from them in the male genitalia by the juxta with digitate lateral processes ( Fig. 21 ), whereas they are triangular in N. abunda sp. nov. and N. apiculata sp. nov.

Female genitalia ( Fig. 32 ). Abdominal sternite VIII membranous medially, produced quadrately and sclerotized antero-medially, shallowly concave medially on posterior margin.Apophyses anteriores about 2/3 length of apophy- ses posteriores. Ductus bursae nearly as long as corpus bursae, with spines spreading in posterior 2/3, becoming denser posteriorly; ductus seminalis much slender, distinctly dilated basally, arising from anterior 1/3 of ductus bursae. Corpus bursae large, ovate; signum crescent, at posterior 1/4.

Distribution. China (Hainan, Hong Kong, Taiwan, Zhejiang).

Remarks. This species was originally described by Park (2002) on the male specimens collected from Taichung and the female specimens from Pingtung, Taiwan. In our study of N. bisinuata , we found the female that has the same collection data as the male and differs from the female given by Park in the genitalia (2002: 261, Fig. 18 ). Thus, it is likely a mismatch in the original description. We describe the female with illustration herein.
