A new species of cyclopoid copepod, Allocyclops (Allocyclops) austronipponicus, is described from a freshwater habitat in Okinawa Island, Japan. This is the first record of the genus Allocyclops from Asia. The new species is distinguished from its congeners by having the following combination of character states: (1) antennal seta representing exopod present; (2) maxillule with two-segmented palp; (3) legs 1-4 each with inner coxal seta; (4) distal endopodal segment of leg 4 with three inner and one outer setae and two apical spines; and (5) seta present on remnant of proximal segment of leg 5, this seta short in comparison to length of somite.
