• Planktonic copepods were collected from ponds and reservoirs of damsin Okinawa, Ishigaki and Iriomote Islands, the southernmost area of Japan, and fivecyclopoid species, Eucyclops cf. speratus, Mesocyclops ruttneri, M. thermocyclopoides,Thermocyclops crassus and T. taihokuensis, and a calanoid Sinodiaptomussarsi were described. The two species of Mesocyclops and probably S. sarsi arerecorded for the first time from Japan and T. taihokuensis for the first time from theRyukyus. The most abundant copepod was T. crassus except for in the reservoirs ofdams on Ishigaki Island, where T. taihokuensis and M. thermocyclopoides weredominant. A comparison with Kiefer's study of more than 50 years ago on a pond inOkinawa Island indicates that the copepod fauna in the pond has apparentlychanged. Eutrophication and introduction of African cichlid fish are considered aspossible causes. The copepod fauna in Okinawa differs from that on the mainland ofJapan in that some species which are common in the latter are absent in the formerwhere S. sarsi is instead common.
