Notes. This is a common species in high mountain areas of Vietnam. Male and female resemble each other in body color pattern ( Fig. 2a–b, e–f ). Paraprocts are very short in lateral view, cerci are generally axe-shaped, with their blades directed inward and with a small knob along their inner margin, and furnished by a robust hook-shaped latero-apical tooth, so that they look bifid in lateral view ( Fig. 2c–d ). This species is closely related to Anisopleura pelecyphora Zhang, Hämäläinen & Cai, 2014 from Yunnan, southern China. According to the original description, Anisopleura pelecyphora is separated from A. qingyuanensis by its completely hyaline wings, which are distinctly yellow tinted basally in A. qingyuanensis . Cerci of Anisopleura pelecyphora are broader and their margin is more strongly curved than in A. qingyuanensis .

Distribution. Vietnam (Lao Cai, Cao Bang, Lang Son, Vinh Phuc [ Do & Dang 2007, Hämäläinen & Karube 2013], Yen Bai, Phu Tho, Thua Thien-Hue and Quang Nam Provinces), Laos (Xiangkhouang Province) ( Hämäläinen & Karube 2013; Yokoi & Souphanthong 2014), China (Zhejiang, Jiangxi, Hunan, Guizhou, Guangdong and Guangxi Provinces) ( Hämäläinen & Karube 2013).
