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 ).
