Cylindroeme vietnamica: Wang, Xie & Wang, 2022: 129 , figs. 1–2, 9, 12.

Specimens examined. Vietnam: 9 males and 1 female, Dong Van, Ha Giang Province, 2019.IV ( CTN) . China: 1 male, China, Guizhou, Guiyangshi, Huaxiqu, Guizhoudaxue, Nanxiaoqu (South campus of Guizhou University), 2007.IX, Ye Liu leg. ( IZCAS) .

Distribution. China (new record): Guizhou. Vietnam: Ha Giang.

Remarks. This species is recorded from China for the first time. Compared the only one Guizhou specimen with the Ha Giang specimens in CTN, the median struts of median lobe from Guizhou are slightly shorter than one specimen dissected from Ha Giang. However, all other characters, such as the median notch and ridges on pronotum, longitudinal ridges on elytra, are not different. Therefore, we identified it as C. vietnamica .
