Distribution. China (Anhui, Fujian, Guangxi, Guizhou, Hainan, Hubei, Hunan, Jiangxi, Shandong, Sichuan, Yunnan, Zhejiang).

Remarks. This species seems to be closely related to N. azumai Asahina from the Yayeyama Islands of southern Ryukyus in having the similar wing pattern, but can be easily distinguished by the aedeagus with the moderately inflated apex in lateral view. In N. azumai , the apex of aedeagus is not inflated ( Asahina, 1988). Weele (1910) placed N.

fraternus as a subspecies of N. sinensis . However, according to his photo of this species, R3 and R4 are obviously not curved backward apically, showing a great difference from the N. sinensis complex. Therefore, N. fraternus is a distinguished species and should not be a member of the N. sinensis complex.
