Forty-seven ostracod species belonging to 27 genera from the Late Devonian in South China are described and figured. The ostracod assemblage from the Nandong section should be attributed to the rhenana-linguiformis conodont zones. The ecological assemblages of ostracods from the Yangdi section correspond to the smooth-podocopid association accompanied by some pelagic entomozoids, which implies an environment of carbonate platform-slope during an ongoing regression. The ostracod faunas from the Nandong section are composed of both pelagic and benthic ostracods and pelagic forms dominate in specimens, which suggesting a basin environment.
