Abstract. The Australian members of the cucujoid family Cerylonidae are revised; descriptions of particular genera and species and keys to their determination are provided. Three new genera (Australiorylon, Lawrencella and Hypodacnella) and 22 new species are described: Australiorylon neboissi, A. setosus; Cerylonopsis corpulentus, O. doyeni, C. australis, C. elongatulus; Philothermus tasmanicus, P. rotundus, P. oculatus, P. macrosetosus, P. microsetosus, P. norfolkie7isis, P. margaretae-, Lapethus queenslandicus, L. peckorum; Lawrencella costata; Hypodacnella kasiae, H. sebastiani, H. euxestoides; Euxestus matthewsi, E. elongatulus, E. fun- gorum. After revision, the family contains in Australia 11 genera and 39 species with close affinities to the Oriental fauna, and much less to the New Zealand one. Brief discussions on phylogeny and zoogeography of the Australian cerylonids are included.
