| Summary: | The genus Apotropina (Diptera, Chloropidae) has a global distribution with more than 80 valid described species, of which 22 are known to occur in Australia. The Australian Apotropina fauna is poorly studied, with many species known from single type specimens, more with the morphology of the other sex unknown, and there have been no new species descriptions since 1959. Here, we describe two new species from Australia, A. maculigena Riccardi, sp. nov. and A. popeye Ang, sp. nov., and provide an updated illustrated key. We also provide a conspectus of the known Australian Apotropina with images of types and collate all original descriptions and subsequent taxonomic notes of relevance as supplementary information. Finally, we discuss the validity of two known syntype specimens of A. bispinosa due to incongruencies with the species description.
