Myopsalta atrata (Goding & Froggatt) is redescribed in light of recently collected specimens that match the original type material. New evidence shows that M. atrata is restricted to the Hawkesbury Sandstone region, specifically in the vicinity of Greater Sydney in New South Wales, Australia. Two new species of Myopsalta are described from central western New South Wales: Myopsalta libritor sp.nov. and M. coolahensis sp.nov. Both occur in grassland, typically in association with alluvial terraces. In addition to morphological redescription, the species-specific calling song for each taxon is documented here for the first time.
