Abstract - Approximately 30 species of the genus Copidognathus were found in the intertidal and subtidal zones of Rottnest Island, southwestern Australia. Twelve new species are described in the present paper: Copidognathus ampliatus sp. nov., C. bispinus sp. nov., C. bistriatus sp. nov., C. caelatus sp. nov., C. canaliculifer sp. nov., C. crassispinus sp. nov., C. dubiosus sp. nov., C. laminifer sp. nov., C. multiporus sp. nov., C. nasutus sp. nov., C. lunctellus sp. nov., and C. strigellus sp. novo They all belong to the gibbus group. A key to the species is presented. The majority !)f species have closely related congeners in the Atlantic and Pacific oceans. Two couples, bispinus-laminifer and ampliatus-caelatus, are almost identical in dorsal aspect.
