Collections of isopod crustaceans from a wide variety of intertidal marine habitats in Queensland. Australia, contained five new species and a new genus of eubranchiate sphaeromatids. Descriptions are given for the different stages of their growth and some ecological considerations are discussed. The new genus is Paradella and the new species are: Paradella octaphymata, new genus, new species; Dynamenella liochroea, new species; D. ptychura, new species; D. trachydermata, new species; and Ischyromene polytyla, new species. Ischyromene Racovitza, Dynamenella Hansen, Cymodocella Pfeffer, and Dynamenopsis Baker are redefined and rediagnosed. The importance of founding species on descriptions of adult males is stressed, but this should be supplemented with descriptions of all other stages of the life cycle if possible. The form of the brood pouch of the ovigerous female and the form of the penes and appendix masculina of the mature male should be included as these characters are relatively consistent at the generic level.
