The specific epithet is named after the Kuankuoshui Nature Reserve.	en	Lin, Aili, Yang, Ding, Li, Weihai (2025): A new species and a new synonym of the genus Nemoura Latrielle, 1796 (Plecoptera: Nemouridae) from China.

8E488781F36DAC6A94D5F815FD23740D.taxon	discussion	Remarks. The new species belongs to the N. ovocercia group. The male epiproct and female paragenital plate of N. kuankuoshui sp. nov. are similar to N. formosana Shimizu, 1997, but it easily separated from the latter by the rounded cercal apex in males and truncate posterior margin of pregenital plate in females; for N. formosana, the male cercal apex bears an anterior hook and the posterior margin of pregenital plate in females is produced and rounded (see figs. 39, 47 in Shimizu 1997). For the Chinese mainland species in the group, the epiproct of N. geei Wu, 1929 and N. longistyla Zhao, Rehman & Du, 2023 are moderately similar to that of N. kuankuoshui sp. nov., but in those species, the median long projection is much longer than that in N. kuankuoshui sp. nov. (see fig. 41 in Shimizu, 1997 and figs. 6 C – D in Zhao et al. 2023).	en	Lin, Aili, Yang, Ding, Li, Weihai (2025): A new species and a new synonym of the genus Nemoura Latrielle, 1796 (Plecoptera: Nemouridae) from China.

8E488781F369AC6A94D5FE30FF157110.taxon	discussion	Remarks. Nemoura lixiana Chen, 2020 was recently described from Lixian County, Sichuan Province, without being placed in any group of Nemoura. Chen (2020) noted its similarity to N. geei. However, the cerci of the Beijing population as noted above have extra stout spines on inner membrane, a character defining his species. For females of the Beijing populations, the sternum 8 has wider lateral sclerite, but bears small lateral pit that is considered only in Sichuan population by Chen (2020). Thus, we herein placed N. lixiana as a subjective junior synonym of N. geei.	en	Lin, Aili, Yang, Ding, Li, Weihai (2025): A new species and a new synonym of the genus Nemoura Latrielle, 1796 (Plecoptera: Nemouridae) from China.
