Two species (Lucicutia clausi, L. flavicornis) of Lucicutia (Lucicutiidae Sars, 1902) have been reported in Korean waters and one species(L. gaussae) is newly added the Tsushima Warm Current realm. Specimens from Korean waters are morphologically consistent with previous morphological characteristics of L. gaussae, but these differ in the following characteristics: 1) the male antennule with one process on segments XIX-XX, one process on segment XVIII, and three processes on segments XXI-XXIII; 2) in male leg 5, basis of left leg in the Korean specimen with small spine processes on the protrusion; 3) in male leg 5, the third exopodal segment of left leg without an inner marginal spine. In this study, we provide a redescription of L. gaussae insufficiently described by previous authors.
