(Fig. 10)

Nemoura perforata Li & Yang, 2006: 58; Yang, Li & Zhu, 2015: 381; Yang & Li, 2018: 20.

Female (Fig. 10). Sternum 7 extended medially forming a well-developed, broadly rounded and swollen pregenital plate, which is strongly sclerotized, overlapping sternum 8 completely and reaching anterior margin of sternum 9. Sternum 8 shortened, with a pair of pale vaginal lobes on the posterior margin, partly hidden by posterolateral edge of pregenital plate. Sternum 9 slightly extended anteromedially, trapezoidal; paraproct wide triangular, with blunt apex.

Material examined. 1 male (COI NO. C125) (HIST), China: Guangxi, Laibin City, Jinxiu Yao Autonomous County, Dayaoshan National Natural Reserve, Yinshan Park, 24°10'07" N, 110°14'38" E, 1130 m, 2020. VI.11, light trap, Mo RR, Lai Y et al.; 1 female (HIST), same data as above, 2020. VI.11; 2 males (COI NO. C13, C14) and 1 female (COI NO. C16) (HIST), Guangdong, Shaoguan City, Chebaling National Nature Reserve, Xiba, 24°43'48" N, 114°15'36" E, 360 m, 2016.IV.28 , light trap, Luo XY, Liu YQ, Xun HS & Zhao YS; 1 female (COI NO. C12) (HIST), same data as above, 2016. V.1.

Distribution. China (Fujian, Guangdong and Guangxi).

Remarks. This species was originally described by Li & Yang (2006) from Maoershan National Nature Reserve of Guangxi, and recently reported from Fujian Province by Yang et al. (2015). We add Guangdong Province to the known distribution. The female was associated with the male by molecular study, and is described for the first time. Unfortunately, no distinctive character was found for morphological distinction from other local Nemoura females.
