The specific name refers to the type locality, Yintiaoling National Nature Reserve.	en	Wang, Xinyi, Zhang, Yao, Li, Weihai, Mo, Raorao (2026): A new species of the genus Hemacroneuria (Plecoptera: Perlidae) from China, with a supplementary description of H. baotianmana Chen & Hou, 2020.

03E3878CFF8EFFAA74D182BC9D74FA82.taxon	discussion	Remarks. The new species is most similar to Hemacroneuria kondratieffi Li, Murányi & Li, 2022 in color patterns of head and pronotum and the general structure of aedeagus, but can be distinguished by the transversely elliptical hammer, the strongly convex inner margin of paraprocts and two pairs of aedeagal lateral lobes. In contrast, H. kondratieffi possesses a generally rounded hammer, thinner paraprocts with slightly convex at inner margin, and more slender dorsolateral lobes of aedeagus. Moreover, terga 1 – 4 of H. kondratieffi are mostly pale with dark lateral margins, whereas those of the new species are uniformly brownish (see figs. 1 – 2 in Li, Murányi & Li, 2022).	en	Wang, Xinyi, Zhang, Yao, Li, Weihai, Mo, Raorao (2026): A new species of the genus Hemacroneuria (Plecoptera: Perlidae) from China, with a supplementary description of H. baotianmana Chen & Hou, 2020.

China (Henan and Shaanxi provinces).	en	Wang, Xinyi, Zhang, Yao, Li, Weihai, Mo, Raorao (2026): A new species of the genus Hemacroneuria (Plecoptera: Perlidae) from China, with a supplementary description of H. baotianmana Chen & Hou, 2020.

03E3878CFF89FFAB74D182F19CAAFF5B.taxon	discussion	Remarks. The male holotype of Hemacroneuria baotianmana Chen & Hou, 2020 was collected in Henan Province, while the paratypes (four females) were collected in Shaanxi Province. Although the specimens of both sexes share consistent overall pigmentation, the two collection sites are approximately 300 km apart. All our specimens of both sexes were collected in Shaanxi Province. The overall coloration, paraprocts, sensilla basiconica patches on tergum 10 and the shape of subgenital plate of our specimens all agree well with the original descriptions by Chen & Hou (2020) (comparing figs. 2 – 6 in Chen & Hou 2020 and Figs. 3 – 5), especially the lobes of the partially extruded aedeagus. This constitutes new evidence for the conspecificity of the two sexes. Additionally, we provide a more detailed structure of the aedeagus to facilitate the identification of this species. The detailed aedeagus structure closely resembles that of H. kondratieffi Li, Murányi & Li, 2022. In contrast to H. baotianmana, the dorsolateral lobe in H. kondratieffi is elongate and dorsally oriented.	en	Wang, Xinyi, Zhang, Yao, Li, Weihai, Mo, Raorao (2026): A new species of the genus Hemacroneuria (Plecoptera: Perlidae) from China, with a supplementary description of H. baotianmana Chen & Hou, 2020.
