Diagnosis. First pedigerous somite not fused to cephalothorax, but covered with cephalothoracic shield. Fifth pedigerous somite smooth. Genital double-somite with large depression around single median copulatory pore, with small ovoid receptacula seminis. Spermatophores glued together, forming large but compact triangular flap. Caudal rami long and slender, with minute proximal lateral setae. Antennula 13-segmented in female, 16-segmented in male. Antenna with two exopodal setae. Mandibula with two setae on first endopodal segment, and three setae on last exopodal segment. Maxillula with four setae on basis, seven setae on endopod, and four setae on exopod. Maxilliped long and slender. All swimming legs with three-segmented exopods and endopods, without inner seta on first exopodal segment, and with two rows of spinules on intercoxal sclerite; second endopodal segment of first to third legs with single seta, that of fourth leg with two setae; third endopodal segment of first and fourth leg with five setae, that of second and third leg with six setae; third exopodal segment of first to fourth leg with spine formula 3.4.4.3 and seta formula 5.5.5.5. Fifth leg in both sexes two-segmented, with single outer seta on first segment; second segment in female with three spines and single apical seta; second segment in male with six elements (three spines, one apical seta, and two spiniform inner setae). Sixth leg with three elements in male and two in female. Third exopodal segment of male second leg with distal spine fused to somite, smooth, and shorter than other spines.

Etymology. The generic name is composed of the country name Korea and the existing generic name Cyclopina Claus, 1862 , the latter being the type and most speciose genus of the Cyclopinidae .
