New combinations are Anterhynchium decoratum (de Saussure), A. tamarinum inviolatum (Giordani Soika), Australodynerus flavoniger (Giordani Soika), Deuterodiscoelius confusus (Giordani Soika), D. ephippium (de Saussure), D. insignis (de Saussure), D. spinosus (de Saussure), Euodynerus aborigenus (Borsato), E. alaris (de Saussure), E. angulatus alexandriae (Giordani Soika), E. angulatus angulatus (de Saussure), E. aspra (Giordani Soika), E. clypalaris (Giordani Soika), E. flavus (Giordani Soika), E. pallidus (Giordani Soika), E. succinctus purgatus(Giordani Soika), E. succinctus succinctus (de Saussure), Pararrhynchium desaussurei (Borsato), P. kurandensis (Giordani Soika), Pseudalastor aurantiacus (Borsato), P. pecularis (Borsato), Stenodyneriellus aurantiacus (Giordani Soika), S. aurantiopilosella (Giordani Soika), S. cylindrellus (Giordani Soika), S. longebispinosa (Giordani Soika) and S. occidentatus (Giordani Soika). Revised combinations are Australodynerus yanchepensis nigrithorax Giordani Soika and A. yanchepensis yanchepensis Giordani Soika, which are returned to that genus. Other new synonymies are Anterhynchium tamarinum septentrionale Giordani Soika = Anterhynchium tamarinum tamarinum (de Saussure), Ischnocoelia robusta analis Giordani Soika = I. robusta robusta (Meade-Waldo), Pseudabispa bicolor flavescentula (Giordani Soika) = P bicolor bicolor (de Saussure), Pseudalastor tridentatus septentrionalis Giordani Soika = P. tridentatus tridentatus Giordani Soika and Rhynchium australense Perkins = R. magnificum Smith.
