Byblisoides esferis J. L. Barnard, 1961 is recorded from southeastern Australia, the first record of the genus in Australia. These bring the number of eastern Australian species to twenty-six. Distributions of three other species are extended northwards into Queensland. A key to all eastern Australian species is provided.
