The taxonomy of the Australian species of two Ropalidia species groups, the R. stigma group and R. variegata group, is revised and their distribution patterns are discussed. Two species in the R. stigma group (R. darwini and R. elegantula), and four species in the R. variegata group (R. flavinoda, R. gregaria, R. mutabilis and R. revolutionalis) are recognized in Australia, with a new synonymy of R. mutabilis torresiana Richards, 1978, under R. gregaria (de Saussure, 1854). Icaria torrida Smith, 1863, from Seram Island is synonymized with R. unicolor (Smith, 1859).
