AssrRAcr. The genus Ocrisiona Simon is revised. Eight speciesare diagnosed,described and illustrated, five new ones are established: O. eucalypti, O. koahi, O. parmeliae, O. victoriae and O. yakatunyae. Four species, O. aerata (L. Koch), O. elegans (L. Koch), O. frenata Simon and O. parallelistriata (L. Koch), are excluded asnot related,three additional ones,O. complanata (L. Koch), O .fusca (Karasch) and O . invenu.slc(L. Koch), are transferred to . The genusis redefined and its relationships are discussed.Remarks on biology are presented,maps of distribution and key to the species are given. Geographical distribution of Ocrisiona is limited to Australia and adjacent areas; O. leucocomis(L. Koch) and O. melanopygaSimon are mainland speciesalso recorded from , andO. melancholica (L. Koch) is also known from Lord Howe Island.

Taxonomic Survey Relationships. General similarities to some speciesof Holoplatys (Zabka, in preparation): body shape,genitalia and legs structure shows both genera to be closely allied. Ocrisiona Simon, 1901 The morphology of particular species, especially their cephalothorax proportions and leg spination suggest that Marptusa [part] L.
