Chalogaster spatulata, new genus and species, is described from Viet Nam and northern Thailand. The genus belongs to the subfamily Stenogastrinae, a group of social wasps endemic to the Oriental Region. Cladistic analysis indicates that Chalogaster is the sister-group of the genus Metischnogaster van der Vecht. A revised key to the genera of Stenogastrinae is presented.
