The Australian Hemerobiidae are revised, and keys and illustrations provided to facilitate identification of all known species. The 34 species are referred to 10 genera, one of which (Notherobius) is described as new. Thirteen new species are described in the genera Psychobiella (one), Psectra (two), Carobius (six), Notherobius (three) and Zachobiella (one). Several specific synonyms are established, and the genera Oxybiella and Drepanomina are synonymised with Megalornina. Kimminsiella is synonymised with Psectra.
