A taxonomic study on the genus Ectopioglossa Perkins from Vietnam is presented. Two species, E. henseni Gusenleitner, 1990 and E. taiwana (Sonan, 1938), are recorded as new to the vespid fauna of Vietnam. A key to the Ectopioglossa species known from Vietnam is also provided based on external morphological characters.
