  • The genus Nippoleucon was newly established within the family Leuconidae and two Hemileucon species, N. hinumensis (Gamo, 1967) and N. enoshimensis (Gamo, 1967), were transferred to this genus. Through examination of the cumacean specimens from the Gwangyang Bay of the Korea Strait, N. hinumensis is recorded as new to Korean fauna. The genus Nippoleucon is reported from Korea for the first time.

  • Only four species of leuconids have been recorded in Korea, all belonging to the genera Eudorella Norman, 1867 and Nippoleucon Watling, 1991. In this study, Pseudoleucon japonicus Gamô, 1964 belonging to family Leuconidae Sars, 1878 is newly recorded for Korean cumacean fauna. Also, for the first time, the male of the species is fully described and illustrated. The specimens were collected from the exclusive economic zone (EEZ) in the western sea (Yellow Sea) of Korea, with a rectangular dredge during 2007-2008. This species is characterized by the following features: the carapace has strong serrations on the antero-lateral margin and a pair of short oblique ridges on the side surface; the ridges begin near the end of frontal lobe and merge with the dorsal median carina; the appendages, such as antenna 1, pereopod 2 and uropod have a lot of simple setae decorated with a bundle of hairs at the end. The present study represents the first record on the genus Pseudoleucon Zimmer, 1903 from Korea.

  • A new species of leuconid cumaceans, Nippoleucon projectus n. sp. is described on the basis of the specimens collected from western shallow coast of the South Korea. This new species is easily distinguished from two previously recorded species (N. hinumensis and N. enoshimensis) in having the fifth abdominal segment prominently projected to rear at dorsal posterior portion and the carapace of the female with three spines on the frontal lobe.
