Yan, Yanhua, Ma, Cunxin, Yang, Ding & Li, Weihai, 2022, Species of Nemoura (Plecoptera: Nemouridae) from Qinghai, China, Zootaxa 5168 (4), pp. 485-493 : 491

Nemoura securigera Klapálek, 1907

Material examined. 1 male ( HIST): China, Qinghai Province, Menyuan County, Xianmi Town, Qihankaigou ( Qihankai valley ), 2694 m, 37.1585º N, 102.0311º E, 3.VII.2021, leg. Weihai Li, Rongrong Shen ; 2 males ( HIST): Qinghai Province, Menyuan County, Deqian Village , 3001 m, 37.2180º N, 102.2098º E, 2.VII.2021, leg. Weihai Li.

Distribution and ecology ( Figs. 4a, e–f ). The species is known only from China: Nei Mongol Autonomous Region, Qinghai and Shaanxi provinces ( Yang & Li 2018). It was redescribed by Li et al. (2013) from Nei Mongol under the name Nemoura cf. securigera Klapálek, 1907 . We recently found this species at several localities in the Qinling Mountain, Shaanxi, the type locality of the species (unpublished data). We believe that the populations in Nei Mongol and Qinghai represent the same species as the Qinling populations. The species was never found in Qinling during summer surveys of recent years, but occurs during summer in Nei Mongol and Qinghai. It emerges from early April Nei Mongol and Qinling (unpublished data). Two of the Qinghai males were collected together with N. jixiangwangi at Deqian village ( Fig. 4a ), and another one was found in a forest stream at Qihankai valley ( Fig. 4e ).
