Kojima and Carpenter (1997) in their catalog of species in the polistine tribe Ropalidiini stated that Ropalidia sumatrae occuring in Vietnam as they cited van der Vecht (1941: 181): Indo China: 1 female, Haut Mekong, Vien Ponkha, May ‚18, R. V. DE SALVAZA {British Museum}, but that local name was not Vietnamese name, probably it was a local name in Laos. Pham and Li (2015) also listed the species as occuring in Vietnam, but give no more information; maybe they followed Kojima and Carpenter (1997). In our study, the species was recorded in one province in the central high land of Vietnam (Tay Nguyen), which confirmed the occurrence of the species in Vietnam after 20 years of doubtful information.
