The cleptoparasitic bee genus Euaspis Gerstäcker, 1858 is reviewed from Vietnam, with four species recognized. A new species, Euaspis flavorotundata Tran & Engel sp. nov. from Northern and Central Highlands, Vietnam is described and figured. The distribution area of E. aequicarinata Pasteels, 1980 and E. polynesia Vachal, 1903 in the country is updated. Notes on the female morphology variation of E. diversicarinata Pasteels, 1980 are provided along with an illustrated key to Euaspis species from Vietnam.
