Distribution. China (Guangdong, Guangxi, Guizhou, Henan, Hubei and Yunan); Laos; Vietnam; Thailand; Myanmar. The species is included in the revision of Taiwanese Neoperla by Sivec & Zwick (1987), but as a mainland species and no Taiwanese specimens were enumerated among the material examined.

Remarks. Both sexes of most examined Guangxi specimens agree well with illustrations and redescription of the designated lectotype: (compare Figs. 23–24 with figs. 9–13 in Sivec & Zwick 1987). However, the male from Huaping ( Fig. 24 ) differs slightly in the spinulation of the aedeagal sac. This variation was already reported for Yunnan specimens of N. cavaleriei , and the species was considered a probable complex with N. lui Du, 2004 (in: Du & Sivec 2004) ( Li et al. 2014c). We note that N. kachin was not considered as a junior synonym of N. cavaleriei by Sivec & Zwick (1987). Only the female sex of N. kachin , figured in the original description ( Stark & Szczytko 1979), was considered conspecific with N. cavaleriei . Nevertheless, the specific identity of N. kachin is in need of clarification, since the details of aedeagal sac spinulation was not described.
