Discussion. After Li et al. ’s (2014) study, the species was mainly distributed in China (Yunnan: Cangyuan, Jinping, Maguan, Malipo, Menghai, Mengla) and Vietnam. In the original description, Ocellar n aca emeie nsis Li, Fang, Liu & Li, 2014 was recorded in Sichuan and Guangxi. While in Bian’s list, Ocellarnaca emeiensis was only recorded in Sichuan, and the specimens from Guangxi were treated as a new undescribed species. From 2017 to 2022, our group collected a large number of specimen and found that Ocellarnaca emeiensis is mainly distributed in northern Guangxi while Ocellarnaca angulata Gorochov, 2004 in southern Guangxi nearing the China-Vietnam border.
