03CF3510106BFF940AD1FC94FE96F8A1.taxon	etymology	Etymology. The species is named after Dr. Chen-Fu Wu in memory of his contribution to stonefly research in China.	en	Wang, Yingying, Wang, Guoquan, Li, Weihai (2024): A new species of Etrocorema from Yunnan, China, with a redescription of the male of E. hochii (Wu, 1938) (Plecoptera: Perlidae).

03CF3510106BFF940AD1FC94FE96F8A1.taxon	distribution	Distribution. The species was collected at light in the regions of the Huanglian Mountains, Yunnan Province, China.	en	Wang, Yingying, Wang, Guoquan, Li, Weihai (2024): A new species of Etrocorema from Yunnan, China, with a redescription of the male of E. hochii (Wu, 1938) (Plecoptera: Perlidae).

03CF3510106BFF940AD1FC94FE96F8A1.taxon	discussion	Remarks. The male of the new species is characterized by an L-shaped aedeagus and a brown sclerite on the ventral surface of the aedeagal sac. It is most similar to E. yunnanensis from Mengla County, Yunnan Province, in sharing a similar head pattern, leg pattern and external terminalia. In E. yunnanensis, the head has a triangular stigma which is dark from the pale M-line to the ocelli and the aedeagal tube is straight and lacks a ventral sclerite on aedeagal sac (see figs. 2 a, 5 in Chen, 2020). The hexagonal stigma on the head of E. wui is larger than in E. yunnanensis. Though E. hochii shares a similar head pattern with E. wui, it lacks the sensilla basiconica on tergum 7 of E. wui.	en	Wang, Yingying, Wang, Guoquan, Li, Weihai (2024): A new species of Etrocorema from Yunnan, China, with a redescription of the male of E. hochii (Wu, 1938) (Plecoptera: Perlidae).

03CF35101068FF900AD1F9F9FC6FFDBF.taxon	distribution	Distribution. The species is only known from Hainan Island, China.	en	Wang, Yingying, Wang, Guoquan, Li, Weihai (2024): A new species of Etrocorema from Yunnan, China, with a redescription of the male of E. hochii (Wu, 1938) (Plecoptera: Perlidae).

03CF35101068FF900AD1F9F9FC6FFDBF.taxon	discussion	Remarks. Our specimen from Yinggeling National Nature Reserve, Hainan Island, clearly agrees well with the original description (see figs. 310 – 311 in Wu, 1938) and the March collection of the holotype. In the studied specimens, patches of sensilla basiconica on tergum 7 were separated while the patch was undivided in the holotype (see figs. 310 – 311 in Wu, 1938) which is thought to be intraspecific variation. Given the close match with the original description and the loss of the holotype specimen, we designate a neotype to solidify the concept of the species. This species is similar to E. yunnanensis and E. wui, which was mentioned above. We provide color figures of adult male of the neotype to help identify this species. The neotype’s entire mitochondrial genome was sequenced in 2019 and its Genbank accession number is MK 905888 (Liu et al. 2019).	en	Wang, Yingying, Wang, Guoquan, Li, Weihai (2024): A new species of Etrocorema from Yunnan, China, with a redescription of the male of E. hochii (Wu, 1938) (Plecoptera: Perlidae).
