Three species of brackish-water ostracods, Dolerocypria mukaishimensis Okubo, 1980, Paracypria inujimensis (Okubo, 1980), and Ishizakiella supralittoralis (Schornikov, 1974), were collected from the same locality at Ushimado, Okayama Prefecture. The male of the candonid P. inujimensis is figured for the first time and described. This is only the second record of this species. Additionally, this report of Ishizakiella supralittoralis is the first of the species and genus from the Inland Sea of Japan ; I. supralittoralis is widespread around Japan and its distribution considerably overlaps that of I. miurensis (Hanai, 1957). Previously, both species of Ishizakiella were presumed to have similar habitat requirements, but the distribution of I. supralittoralis and its coexisting species suggests that it has different habitat requirements than I. miurensis does.
