  • Two newly recorded species belonging to the genus Lamprops, family Lampropidae found in the East Sea (Sea of Japan) of Korea are reported: Lamprops carinatus Hart, 1930 and L. pseudosarsi Tsareva and Vassilenko, 1993. Lamprops carinatus is characterized by having a smooth carapace without oblique ridges and one long and two pairs of terminal unequal setae on the telson. Lamprops pseudosarsi is easily distinguished by having two pairs of oblique ridges on the carapace and one long and two pairs of terminal subequal setae on the telson. The collected specimens were congruent with the original descriptions, except for several minor differences. This is the first record of the genus Lamprops from Korea. Especially, new information on the mouthparts of these species is given, and the male of L. pseudosarsi is described for the first time. Keys are also provided to the Korean genera of the Lampropidae and species of Lamprops.

  • This study deals with the Korean cumaceans collected from the coast of the Yellow Sea and other Korean waters. Three species in two families (Lampropidae and Bodotriidae) are identified as new records for Korean fauna: Hemilamprops californicus Zimmer, 1936, Bodotria parva Calman, 1907 and Iphinoe sagamiensis Gamo, 1958. They are redescribed and figured in detail. The two genera, Hemilamprops and Iphinoe, are reported for the first time from Korea.

  • 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.

  • In this study, a new species, $Dimorphostylis$ $breviplicata$ n. sp. is described and illustrated on the basis of specimens collected from the shallow Korean waters. This new species is similar to $Dimorphostylis$ $brevicaudata$ (Zimmer, 1903), $Dimorphostylis$ $acroplicata$ Harada, 1960 and $Dimorphostylis$ $valida$ Gam$\hat{o}$, 1962 in that the carapace has three pairs of oblique ridges on the surface. However, the new species is distinguished by the combination of the following features: the middle oblique ridge is short and not joined to the other oblique ridges; the transverse ridge is absent on the frontal lobe; the dorso-median process on the pereonite 5 is only barely visible; the male telson has no short stout seta on the both lateral margins; the length ratio of the first to remaining articles combined on the male uropod is 1 : 0.7. A key to the Korean $Dimorphostylis$ species is provided. Also, $Diastylis$ $alaskensis$ Calman, 1912 is redescribed as a new recorded species of the Korean fauna.
