Martens, 1977 Cypridopsis biwaensis Okubo, 1990a Remarks This widespread species was previously reported from the Korean Peninsula ( Chang et al. 2012 ). Similar to the previous Korean report, the longest seta of the antennal exopodite is long, reaching beyond the distal end of the second endopodal segment. On Jeju Island this species was encountered only once, from the lower reaches of a river (locality 35).
