03A787BAFFA1FFF8AFD7FF183948BDA3.taxon	description	Male (Figs. 2 – 6). Body length 4.8 – 4.9 mm. Forewing length 5.5 – 5.6 mm, hindwing length 5.1 – 5.2 mm. Terga 5 – 10 with sclerotized anterior margins. Tergum 9 slightly concave at midlength and sclerotized at anterior margin, without posteromedial lobe. In lateral view, not elevated (Figs. 3 b – 3 c). Tergum 10 strongly sclerotized at anterior margin, with a deep subtriangular indentation (Figs. 3 a, 3 d). Sternum 9 bearing an elliptical, hairy medium sized to large, longer than wide vesicle, posteriorly nearly reaching 1 / 2 of the subgenital plate. Subgenital plate semi-elliptical with sclerotized margins (Figs. 3 b, 6 a – 6 b). Paraprocts apical part medium long and tapering. Fusion plate long and narrow (Figs. 3 b, 5 d). The main epiproct sclerite generally quadrate, corners obtuse, bears a hook at the apex. Concavity between main sclerites trapezoidal. Additionally, the inner margin of main sclerite slightly constricted at 1 / 6 and dilated at 5 / 6 (Figs. 3 e, 4 b, 5 a – 5 c). In frontal view, basal sclerite divided from two main epiproct sclerites, with a medial opening between the two main epiproct sclerites (Fig. 4 a). In the lateral view, the main epiproct sclerite subtriangular, the basis of apical flattened but the hook obvious (Figs. 3 c, 5 b). In the ventral view, the main epiproct sclerite cleft and rectangular (Fig. 5 d). Female (Figs. 1, 7). Body length 5.5 – 5.6 mm, forewing length 5.6 – 5.7 mm, hindwing length 5.0 – 5.1 mm. Terga 2 – 10 sclerotized anterior margin, and with membranous medial portion on terga 2 – 8 (Fig. 1). Sternum 7 forming a large trapezoidal sclerite, covering 3 / 4 width of the sternum, the lateral margin sinuous, a small slender subrectangular sclerite present on each side of the plate. The subgenital plate triangular and wide, not protruding beyond sternum 8, anterior to the plate occurring a subtriangular medial sclerite, the sclerite as wide as the membranous area of it. Sternum 8 with two lateral sclerites that extend medially, the lateral margin of the sclerites covering most of the length of the sternum (Fig. 7).	en	Cao, Zhishan, Yang, Ding, Li, Weihai (2020): A new species of Eucapnopsis (Plecoptera: Capniidae) from China.

03A787BAFFA1FFF8AFD7FF183948BDA3.taxon	distribution	Distribution. Yunnan Province, China. The type series is only known from a stream draining Baima Snow Mountain in northwestern Yunnan Province, an area of alpine coniferous forests.	en	Cao, Zhishan, Yang, Ding, Li, Weihai (2020): A new species of Eucapnopsis (Plecoptera: Capniidae) from China.

03A787BAFFA1FFF8AFD7FF183948BDA3.taxon	etymology	Etymology. The species refers to the province where the type locality of the new species is located.	en	Cao, Zhishan, Yang, Ding, Li, Weihai (2020): A new species of Eucapnopsis (Plecoptera: Capniidae) from China.

03A787BAFFA1FFF8AFD7FF183948BDA3.taxon	discussion	Remarks. The new species is generally similar to E. stigmatica. The male genitalia of the E. yunnana is most similar to the E. s. stigmatica. The main sclerite of epiproct of E. yunnana is subquadrate in dorsal view, whereas the epiproct of E. s. stigmatica epiproct is rounded. In frontal view, the epiproct of E. yunnana lacks a rounded medial opening that occurs in E. s. stigmatica. The opening between the two main epiproct sclerites of E. s. stigmatica is narrow, but in E. yunnana, it is wide and its inner margin straight. The subgenital plates of the females of both species are different. The two lateral sclerites in E. s. stigmatica is smaller than that in E. yunnana. The forewing of E. s. stigmatica has six crossveins between the C vein and Sc 1 vein, whereas E. yunnana has only two crossveins. In addition, E. yunnana is also similar to E. s. transversa, but male main epiproct sclerite of E. s. transversa is characteristically flattened (both in lateral view and in frontal view). The male of E. yunnana is also similar to E. quattuorsegmentata and E. brevicauda (Judson & Nelson 2012, Murányi et al., 2014) in the variable morphology of the epiproct, but typical specimens differ in the shape of the two main epiproct sclerites, and the opening between the two main epiporct sclerites. The females of E. quattuorsegmentata and E. brevicauda are distinctly different from E. yunnana by possessing entirely pale subgenital plates.	en	Cao, Zhishan, Yang, Ding, Li, Weihai (2020): A new species of Eucapnopsis (Plecoptera: Capniidae) from China.
